Harpy was stunned for a moment, he didn't expect that it would be so simple, but in a blink of thought, he bypassed this bend, thinking about it, they are all far away from the ocean, the key did not follow, and it had to be transported, how much time did it take, this key should be on the top of the box, it can't be elsewhere.

Looking at the integrated box, Harpy's head grew bigger, and it seemed that there was no flaw at all, how could there be a key?

Harpy's heart was full of doubts, no matter what, just find one to come out and see, Harpy walked to the front of the box, pulled up the handle of the box hard, so heavy feeling, he had a lot of strength, but the small box was still not moving, what kind of metal was contained in this box, so heavy, slightly surprised, looked around on the silver box, inch by inch, on the surface of the slightest can not be seen, almost touched with hands, a little bit of the difference in the surface, This is also the most likely place to put the keys.

After looking for so many days, I finally found a movable steel sheet on the back of the box, in a very inconspicuous position, pushed open the steel sheet, and pushed it hard, the steel sheet opened, revealing a little space inside, and a key that looked like a sheet was suddenly stuck inside, bright and dangling, the same color as the silver-white box.

Sure enough, it is exquisitely designed, God knows, these boxes, how to make zuò out, how much it costs, but this place to put the key, I don't know how many brain cells will be consumed, if it is not Yang Yuanzhao to break it, he may never find the key, the box is too heavy, put it there steadily, no one to move it, and no one will find it, unless it is luck against the sky.

The key is right, stuck in the keyhole, tightly sealed, twisted hard, the circlip quickly popped open, revealing a few small poles, pulled hard along the pole, pulled up a few poles, the box folded up, revealing a small box inside, only a few tens of centimeters square, full of small black particles, fine as sand, fine and dense, filling the entire box, not the gold that Harpy had thought about before, not silver, not platinum, the color is obviously wrong, A metal for sure.

Harpy is a businessman, and has also done steel business, for all kinds of metals, is not unfamiliar, reach out and hold a small handful of powder in his hand, the first feeling is heavy, heavy, some falling, a small handful of metal, if replaced by steel, it will not be heavy, but this metal is sinking to death, obviously the proportion is far above steel.

Pinched it hard, the hardness is very large, not like a simple metal, silently calculated the volume of the box, asked the porter about the feeling, roughly got the weight of such a box, the weight and volume combined, Harpy quickly calculated, the specific gravity of this metal, at least more than 16, or even more, such metal, the entire periodic table, there are not many, associated with the shape, color and hardness of the metal in front of you.

Wolfram? Could it be tungsten, Harpy's gaze finally fell on this tungsten powder, his eyes were full of disbelief, it would be tungsten, obviously, look at the appearance of these tungsten, it is pure metal tungsten, neatly placed in the box, it looks very good, it looks very high-end, these are all, hundreds of boxes, I am afraid that there are not 100 tons, this amount is a lot.

Harpy is an ordinary businessman, as a Jew, well-informed, very clear, the recent role of tungsten, he seems to be a result of the military industry has something to do with it, he inquired before, the price of a ton of tungsten is an astronomical figure, the price per ton, should be between 400,000 marks and 500,000 marks, the fluctuation is more violent.

No wonder Yang Yuanzhao will take this metal as the focus of this ocean transaction, I am afraid that other things of the whole ship, together, are not so much more expensive than tungsten, on the value, the value of tungsten can not be compared with gold, it is also an important precious metal, the most critical is its performance, in the cannon steel, ship deck, protective armor, has a huge and necessary role, especially recently, many scholars in Germany, for tungsten alloy research, continuous emergence results, based on his cannon steel, than the traditional cannon steel, The performance in all aspects is at least two layers higher, which is very rapid for heavy artillery, and tungsten is immediately sought after and is known as one of the most important military masterpieces in Germany.

It was at this time that Germany strengthened the speed of collecting black stone, not only the courtesy and foreign companies, but also discharged a large number of people, directly to the black stone production area in Jiangxi, and purchased black stone at a high price.

Harpy is a steady person, immediately looked for other boxes, and moved five boxes, all of which found the key in that position, opened all the boxes, and inside each box, there was the same powder, he immediately understood what Yang Yuanzhao meant, it turned out that Yang Yuanzhao had not pinned all his hopes on him, maybe there were, but more of it was here, if these things were really tungsten, then this thing not only represents a huge enough wealth to shock, It also represents a huge impact.

Harpy quietly restored the boxes to their original state, and in one of the boxes, he took out a handful, rare and packed them in small bottles, and instructed his staff to focus on keeping these boxes, so that they could be foolproof, and then put down a few things and went to the city of Hamburg.

Hamburg, as the largest port in Germany, has many science and engineering universities, because of the running for Chinese to go to school, rejected by a large number of universities, not accepted Chinese students, Harpy in the university circle, also left a trace, after all, a generous, multi-gold chamber of commerce, for a lot of science and engineering have quite a lot of support for the rich man, just in the universities of Hamburg, has sprinkled 1.5 million marks, the most famous Hamburg University is directly invested 250,000, without involving the fundamental situation of the school, You can get a lot of courtesy.

Under these circumstances, it was easy for Harpy to meet a professor at the University of Hamburg's Department of Metallurgy. Professor Fisher, Deputy Director of the Department of Metallurgy, Ph.D. Supervisor, has a profound knowledge of the field of metals and alloys, and is one of the top ten metallurgical experts in the entire German metallurgical field.

"Professor Fisher, it's a pleasure to meet you!" Seeing Professor Fisher come out in person, he had done a survey of many universities in Germany, and the University of Hamburg was one of them.

"Mr. Harpy, thank you very much for your support of our school and the metallurgical department, I wonder if there is anything I can help you with?"

"That's right, Professor Fisher, I have some metal particles here, and I would like you to do an appraisal!" Harpy took out a small bottle and handed it to Fisher.

Fisher frowned, his face showed a trace of unhappiness, and thought that Harpy was doing something, but found that Harpy just wanted him to do an analysis of the material, analyze what the material was, this matter, not to mention that he was a professor, even if it was an assistant on the side, he could do it, Fisher was unhappy, but he took it, and it was a little bit of a trivial matter, and he donated 70,000 marks to the metallurgical department of the university, and he did it easily, and he did not waste much time.

Open the small bottle, smell it, there is not much smell, it is a relatively pure metal, it is powdery, black, it looks ordinary, a lot of metals are of this color, pour some out in the palm of your hand, Fisher was slightly moved, the specific gravity is not light, the specific gravity of the metal dà is a good metal, it is an additive in many alloy materials, it can improve the alloy material, which is the key research direction of their metallurgical department.

Heavy in his hand, pinched, extremely hard, did not use technical analysis, just a simple look at the appearance, Fisher was stunned for a moment, as a professional, almost instantly, he thought, this metal, maybe tungsten.

Tungsten, but in this era of German metallurgical circles, more popular elements, tungsten is in nature, the highest melting point of the metal, 3380 degrees of melting point, so that he is a natural high-temperature resistant material, has been going in that direction, some time ago, about tungsten alloy began to become popular, high temperature resistance, compression resistance, wear resistance, these things, are extremely important qualities in the military industry, about tungsten alloy, also like mushrooms after a rain, in the surge in use, the value of tungsten has also been valued, Regarding tungsten alloys, one after another, they have skyrocketed.

In itself, tungsten is a high-priced metal, natural tungsten ore, rarely has a very high content, one percent of the content, plus tungsten refining is extremely difficult, the melting point is extremely high, can not be used, the difficulty of refining is very large, so the price is very high.

Now that he has thought of it, and then observe the powder in his hand, it seems that the texture is very pure, it seems to be tungsten with high purity, Fisher suddenly became interested, called a few assistants to help, and entered the real room, the real room of the metallurgical department, a variety of Germany's most advanced machines, after a series of measurements, from chemistry to physics, Fisher finally determined that these powders in front of him are nothing else, it is pure metal tungsten, its purity is extremely large, and the powdering is also very subtle in place. It is an excellent alloy added material, which can be used directly without deep processing.

As a metallurgical expert, Fisher knows very well that the price of tungsten is high, on the one hand, because of the high price, on the other hand, it is because of the great difficulty of purification, waste, coupled with many consumption of energy, machine, labor, etc., resulting in its high enough price.

From this point of view, this so-called German and American is definitely not a simple enterprise, and Fisher even has a sense of re-understanding this enterprise. RS
