If it is said that the research and application of tungsten in this era are the best in Europe and the United States. And among them, the longest history and the most familiar application must be Germany!

At the beginning of 1920, when the German electrical company Light Bulb, OSRAM, was looking for an alternative to expensive diamond drawing dies for the production of tungsten wire. These attempts led to the invention of cemented carbide、It is particularly important that several companies that are about to apply for its high wear resistance. The first tungsten-cobalt grade was soon successfully used in cutting, cast iron, milling, ...... Wait.

In the early 1930s, the company debuted the first cemented carbide steel milling, in addition to tungsten carbide, cobalt, tantalum, titanium carbide carbide also loaded. In addition, by titanium, tantalum carbide, carbide, high temperature wear resistance, hot hardness and oxidation stability cemented carbide is obviously 680 chapters complete! Improve.

And tungsten carbide-tour (telecommunications, niobium) tricobalt carbide cutters have very good cutting steel. Immediately after that, start as a digging tool. The life of tungsten carbide tools used in the first mining is at least ten times longer than that of steel drills!

The Americans also noticed this, and they developed tungsten alloy machine tools for cutting and production. Tu Qianjun took advantage of the Great Depression in the United States to get back a small part of the machine tools, a small part of them have this kind of cutting tools.

It is a pity that several countries are secretive about the application of tungsten ore smelting. I won't reveal it at all, but fortunately, Germany is hard! They need allies, they need all kinds of resources from the three eastern provinces.

Especially soybeans, tungsten, steel and oil in the three eastern provinces, so the opportunity for the three eastern provinces is here again! Tu Qianjun did not hesitate to ask Germany for tungsten technical support, and said that he would provide the best way to apply tungsten to weapons.

This aroused the interest of the Germans, and the Tiger was still very talented in this area. Weapons such as the Tiger assault rifle, the Tiger I tank and the Tiger Shark fighter have proven themselves.

After weighing it, the mustache gritted his teeth and let his technicians come to China. And the direction proposed by Tu Qianjun is to use tungsten to complete the explosion in Chapter 680! Gold is the bullet core, creating a tungsten core armor-piercing bullet!

The German technology is really not covered, and after a toss with these technicians from the Chinese side, they really got it out! Although this bullet is not as good as the armor-piercing bullet of later generations, it is more than enough to be equipped with a 14.5mm heavy machine gun to hit a Japanese tank with only 30mm side armor.

But the big problem is that this bullet is not cheap either! Even if tungsten and steel produced in the three eastern provinces were cast, the cost of the bullet would be enough to make Tu Qianjun's teeth acid.

This time he was also gritting his teeth. A million rounds of tungsten alloy bullets were thrown to North Korea for the Japanese to try. In fact, Tu Qianjun didn't want to take this opportunity to promote tungsten alloy slug in his heart, so that he could sell it for money? !

The Japanese are the best test subjects! If you beat them up, all countries will naturally be able to see it. Those new weapons will surely be of interest to them as well. When the time comes, it's time for you to bargain with them.

At this time, China's tungsten ore is the world's first! That's a lot of money! It's still a big business!

"Tom tom tom...... Rumble! Rumble!! Boom ...... "three times and five divided by two, and these Japanese tanks were blown into pieces all over the ground." Countless Japanese infantry wailed as they were knocked down by flying tank parts, or slashed off their flesh and limbs.

The 14.5 heavy machine gun of the Rhi II type on the mountain also changed the bullets, and they replaced the magazine box with all-steel bullets at this time! Against the Japanese army below, it was a "sudden ......" sweep!

Hit by a 14.5 caliber bullet. The consequences can be imagined! The Japanese soldiers below didn't even hum anymore, and they were directly exploded into a sky of flesh and blood, and fell down scattered with broken internal organs and miserable white broken bones......

Kawagishi Bunzaburo in the rear put down the binoculars painfully, unwilling to look at this miserable scene again...... Killing! This is the naked torture and killing! Whether in the air or on the ground, the Wehrmacht has done a perfect torture against them!

The Type 97 light explosion machine in the sky, the 97 medium combat vehicle on the ground! All of them were completely blown out by the fire of the Wehrmacht! These damn dolphins, where did they learn these techniques?! Bastard! Are all the academies in the Empire idiots?!

Kawagishi Bunzaburo closed his eyes in pain, not looking at the Japanese soldiers who were constantly wailing all over the mountains and fields, and were beaten into flesh and blood. He knew that all he could do at this time was to watch the soldiers being tortured to death.

They can't get out anymore. Sending people to the rescue becomes another impossibility. Those who go can only be sent to death.

"Whoosh...... Rumble! Rumble!! The battle in the sky ...... began again, and the Japanese planes and the eagles of the Fifth Army of the Wehrmacht Air Force finally collided together!

Just like Gao Zhihang and them before, the tactic chosen by Kabini is still to make a firepower cover with a rocket! And then the collective pull-up. Dive and destroy the Japanese fighters with cannons!

Here, we can see the impact of the Japanese army's unfavorable communications! If they had been able to communicate well, they would not have been completely ignorant of the Wehrmacht's tactics and would have rushed to the death like their own colleagues.

Unfortunately, they don't know anything about it. Still stupidly bumped into the Wehrmacht's attack net! This time the results are even bigger than the last one!

One covering fire from the rockets caused more than 300 Japanese fighters to turn into smoke and fireworks, or they were hit by fragments and fell from the sky with black smoke and screaming......

The Japanese fighters, like their colleagues in front of them, were all stupid at once! The whole formation was stunned for at least a few seconds, and in an air battle, these few seconds can already do a lot of things!

"Sudden ......" They were stunned, the war eagles of the three eastern provinces would not let go of this opportunity! The raised eagles have locked on to their targets through the communicator!

With a dive, the I20mm cannon on the plane exploded! The Japanese fighters didn't even have time to react. It was directly bombed into a cloud of fireworks and a pile of debris.

The excited Wehrmacht warhawks finally showed their most hideous minions, and they screamed excitedly to kill the Japanese fighters everywhere! The Japanese army's pitiful 7.7mm machine guns were almost no threat to the Wehrmacht!

The huge difference in maneuverability and horsepower gives this kind of chase to the advantage of the Chinese defense forces! The Japanese could only flee in all directions like leper dogs being chased.

Unlike leper dogs, they are not eaten but blown up when they are caught up. And like the leper dogs, they will also have no bones left.

"Tutu Tu Tu ...... Boom ......" Carbini was satisfied and blasted a Japanese fighter plane trying to escape into the air! This was followed by an emergency pull-up. Quasi-looking for the next target.

Unfortunately, there aren't many targets left for him anymore. The Fifth Army had a total of more than 300 fighters, while the Japanese army dispatched more than 560 fighters this time.

In the first wave of rocket attacks, more than 300 aircraft were killed. Then the eagles swooped down and attacked, not even one per person. Yes. It was more of a slaughter than a battle.

This murderous air battle lasted just over two hours, and the Japanese attacked in two sorties with a total of 1,132 fighters! The Wehrmacht dispatched nearly 700 fighters, and the Japanese finally escaped with only 43 fighters. No more than twenty can escape in their entirety.

The rest were all buried in the sky above the 38th parallel! On the Wehrmacht, there were no casualties except for a few 13 unlucky eggs who were hit by Japanese 7.7mm bullets and were forced to parachute into mailboxes, engines and other parts.

Even if he parachuted, he fell to his own turf and was pulled back to eat by the enthusiastic infantry below.

Air battle result: 13 to 1089! Japanese Army, by the Wehrmacht Air Force units. Boom!

And this kind of complete explosion is based on the development of the three eastern provinces over the years, and on the absolutely advanced foundation from fighter planes to pilots to command and combat concepts!

After getting the statistical results, Chen Haihua is very proud as the commander of the Air Force! Once upon a time, we were beaten backward! Now, let's go in and fight back! Beat you little Japan! Hahaha......

"Little Kana came back and told him that Lao Tzu invited him to drink! Doesn't he *** love the French guy's girl-like red wine?! The old man doesn't want this year's salary, so he buys him a box of drinks! Hahaha......"

Chen Haihua was very proud, and Lin Leopard was also laughing wildly! The results were really good, and the most important thing was that not a single brother was left behind! All alive. Except for a few unlucky eggs who were hit by stray bullets and sighed in the hospital in the rear, the rest of the cubs were all jumping and celebrating alive!

The troops of the Japanese attack position this time were at least one wing. Fifty ninety-seven tanks were mobilized to help in the battle, but unfortunately all of these two goods were lost on the position! Not even the first two hundred meters of the Wehrmacht positions rushed in.

reminds me of the Battle of Jinan. The little devils are all smashing cannonballs on the heads of Lao Tzu! How many men have been harmed by them like this! There is also 918, speaking of which, no one in the Wehrmacht does not hate itchy!

Those tens of thousands of Japanese troops caused great damage to the Wehrmacht! It's good now! These fools finally know who daddy is! Let's beat him with heavy guns and artillery, and beat him all over the ground to find teeth!

"Tell me to go! Wang Mi his kid played well! Lao Tzu, the commander, is very satisfied! Not bad! Lao Tzu wants to reward him! Lin Leopard laughed, but he couldn't find any reward for a while. When I looked back, I saw a military kettle hanging from my bedside.

In that kettle is the fiercest burning knife! The big fan-like hand grabbed the kettle, threw it to the adjutant and said loudly: "Tell Wang Mi that cub!" Give Lao Tzu a good call! This wine is for him! When this battle is over, Lao Tzu invites him to dinner! Hahaha......"

Defeat on the ground, annihilation in the air! Kawagishi Fumizaburo's final choice was to have all the troops withdraw to the fortifications. Thinking of relying on fortifications for defense.

But the Wehrmacht is not stupid to take flesh and blood to fight your fortifications?! Is this necessary for the time being?! Of course, you still have to fight a little. So Jin Jiu's troops in the rear were organized, and they were prepared to attack the Japanese defense line as the charging troops.

The Wehrmacht, on the other hand, was supported only by artillery, bombers and fighter jets, supplemented by a number of commanders. The troops themselves will not move.

Korea lost the war. And the Japanese army is progressing smoothly in the Lingnan area! From the landing in Tamsui, apart from the spontaneous resistance of a part of the peasants, the Japanese army did not encounter any decent attacks!

It wasn't until the march reached Dongguan that it was discovered! There was chaos in the city of Guangzhou, and Yu Hanmou packed up his soft and prepared to evacuate Guangzhou......
