The melting point of tungsten is 3415 °C, which is the highest melting point of all metals, low vapor pressure, good corrosion resistance, color just gray to white transition, pure tungsten is hard and brittle, not easy to process, but can be made into very fine wire and special alloy steel, such as tungsten wire, ferro-tungsten, tungsten steel, tungsten sand (selected tungsten ore).

Here is a special introduction to tungsten special alloy steel - tungsten gold, which is one of the hardest metal materials in the world, the hardness is between 8-9M (Mohs hardness standard), second only to diamond (10M), in addition, the gloss of tungsten gold is not only far better than tungsten steel, and even surpasses all metals known on the earth, tungsten gold has incomparable gloss, refraction and texture after high-polishing mirror and other processes, with jewel-like color and brilliance.

Tungsten gold is also widely used, such as turning tool bits for processing, tungsten wires for lighting equipment, and various heat conductors; batching of crankshafts and cylinder barrels of high-end automobiles; Ingredients for casting various special steels; It is widely used in the manufacture of guns, artillery, rockets, satellites, aircraft, ships, as well as popular accessories such as jewelry.

Tungsten has outstanding physical properties, a wide range of applications, and naturally a high value.

At present, the spot price of tungsten bar in the international market is about 310 yuan/kg, and the higher the purity, the higher the price.

Lu Wei still had some slight difficulties in making tungsten ingots from the tungsten gold warheads of the collected cannon armor-piercing shells.

The melting point of tungsten gold is too high, more than 3400 degrees, and in the melting state, almost any container cannot be contained, because it is like a cup made of ice cubes to receive boiled water, and the cup will definitely melt.

Lu Wei naturally took this into account, and the set of molds he bought came to play a role.

He was going to use this mold to make a new set of crucibles, crucible pliers, and deflector grooves.

The material used to make this crucible device is not tungsten gold with a melting point of more than 3,400 degrees, but a metal that only exists in this plane, with a melting point of more than 5,000 degrees, hardness exceeding diamond, and a black crystal color, Lu Wei called this material "black gold".

He plans to make a crucible device out of black gold.

More than an hour later, Lu Wei spent more than 10,000 yuan to buy the set of mild steel molds scrapped, after the black financialization, the temperature close to the surface of the sun, directly let part of this set of molds gas, melt, fortunately, Lu Wei needed this set of crucible device was also made, with a grinding machine to polish the rough inner wall smooth, this new crucible device, Lu Wei began to make tungsten ingots.

This process is similar to making copper ingots, but the tungsten gold warhead is far lighter than the 30-kilogram copper shell, and it only took two hours for Lu Wei to easily produce 100 tungsten ingots, each of which is more than 2kg (the density of tungsten is 2.17 times that of copper).

When Lu Wei moved all the prepared copper ingots and tungsten ingots to the main control hall, they were neatly stacked together, and the crucible device was also placed in a corner, Lu Wei looked at the time, seven or eight hours had passed, and his stomach was grunting with hunger.

Hurriedly eating some snacks and bread, Lu Wei looked at the copper ingots and tungsten ingots stacked in the corner, exuding a yellow, white-gray luster, and his heart was extremely satisfied.

"These metals, adding up to more than 300 kilograms, will take five or six days to move all of them to the other side of the earth, and then sell them to metallurgical companies to make a profit!"

Lu Wei planned like this, of course, he also knew that these copper ingots and tungsten ingots were not gold ingots or silver ingots after all, and they would cost tens of thousands of yuan if they were sold for 300 kilograms, which was far from the goal of getting rich, but it was better to be safe, things like gold and silver were too public, and it would be strange if the whole vehicle was sold and did not attract the attention of some people (of course, Lu Wei did not have a whole vehicle of gold and silver).

Metals such as copper and tungsten have many industrial uses and large quantities, and although Lu Wei cannot make a fortune or get rich all at once by trading these metals, he can develop safely, prudently and for a long time.

After the original accumulation of capital is completed, they will open a company, rent a warehouse, expand the scope of business, and make use of their own advantages, through the two planes, engage in time and space trade, and create their own sphere of influence...... In the future, Lu Wei will definitely become one of the top people on earth.

Of course, money can bring people a sense of accomplishment and satisfaction, but it can't bring a sense of security. His son was kidnapped by kidnappers, and the ransom is not a billion billion, Lu Wei will not become a "fat sheep" in the eyes of some people, and strength will always be his biggest reliance.

Roll up the cover, come to the energy center, and continue to cultivate.

After cultivating these days, Lu Wei has mastered the free energy to a new level.

Now, Lu Wei can already store a certain amount of free energy in his body and keep it for 24 hours.

The realization of this breakthrough, on the one hand, has something to do with the growth of Lu Wei's mental power these days, on the other hand, Lu Wei has been able to control the opening and closing of the pores of the skin all over the body, preventing the escape of free energy in a large area, and this blocking process cannot last too long.

In addition, a shocking characteristic of free energy also gave Lu Wei endless inspiration, and he gradually had a clear understanding of how to use "free energy".

This characteristic is easy ionization.

Kai said before that the particle of free energy (referred to as "free particle]) is an extremely small special particle that is much smaller than the electron, and it is this kind of particle that is easy to combine with electrons to form a slightly negatively charged new particle, which is easy to separate and become [free particle] and [electron] again.

As a result, molecules, atoms, and any object containing electrons may lose their extranuclear electrons and become positively charged particles or objects under the wash of free energy.

After the combination of [free particles] and [electrons], the magical particles generated are still mentally controllable, and under the control of spiritual power, they can travel around the whole body, and even be released from the body.

So, using this characteristic, Lu Wei achieved control over all the nervous systems in his body.

Since Lu Wei can manipulate free energy to artificially create positive and negative electricity, he can intercept, change, dilute, enhance and so on to control these bioelectricity.

It can be said that Lu Wei can now control all the unconditioned reactions of the human body, such as the beating of the heart, the peristalsis of the stomach and intestines, the secretion of glucagon and insulin in the liver, the secretion of adrenaline in the kidneys, the immune system and various endocrine systems, Lu Wei can fully control and become the god of his own body.

This feeling made Lu Wei excited, once he became the god of his body, the invasion of diseases, the degree of brain development, the balance of various systems in the body, the limitation of life expectancy, etc., were no longer a problem for him, and the existence of free energy allowed him to easily transform himself and easily break through the limits of the human body.

Of course, the human body is a delicate and complex system, maintaining a balance, and Lu Wei did not dare to intervene indiscriminately to break these balances, he just found a certain area of the brain, realized the control of the pores of the whole body, and easily opened and closed.

Besides.

Combined with the practice of national arts, through free energy, Lu Wei also invented a very lethal martial art - positive electric fist.

The principle of positive electric fist is very simple, that is, let the [free particles] spread all over the fist, take away the extranuclear electrons of molecules and atoms in the fist cells, and let the whole arm be in a positively charged state, and then punch out, for a time the current surges, the silver snake flies, its power, the shock generated in the opponent's heart, is absolutely infinite.

Lu Wei discovered the principle of positive electric fist, but in the specific practice process, there are still certain difficulties, the current has a certain destructive effect on the biological cells themselves, and the same sex repels, the positive charge stored in the arm can not be too much, and it cannot be controlled if it is too much, and finally runs to the whole body and hurts itself.

But Lu Wei is still very confident, he has found a way to overcome the difficulties, and after a while, when he has practiced positive electric fist, the whole earth, except for guns, missiles, and nuclear weapons, there are not many things that can make him feel afraid.
