Hubby was stunned for a moment, and he didn't expect it to be so simple, but after a second thought, he bypassed this bend. He thought about it, it was all far away from the ocean, and the key had not followed him, and it had to be transported over. How much time would it take? The key should be on the box and could not be anywhere else.

Looking at the box that was integrated, Habi's head became bigger and seemed to have no flaws at all. How could he have a key?

Hubi's heart was filled with doubts. No matter what, just find one to take a look. Hubi walked to the front of the box and pulled up the handle of the box hard. It felt so heavy. He was very strong, but the small box still didn't move at all. What kind of metal is contained in this box? It was so heavy, and I was a little surprised. I searched around the silver box and searched inch by inch. I couldn't see it on the surface at all. I almost touched it with my hands. I felt a little bit different on the surface, and this was also the place where the key was most likely to be placed.

After searching for so much time, I finally found a movable steel sheet on the back of the box, above a very inconspicuous position. I pushed it away and pushed it hard. The steel sheet opened, revealing a little space inside. A key that looked like a sheet was suddenly stuck inside, bright and shiny, the same color as the silver-white box.

It is indeed exquisitely designed. God knows how these boxes will cost. It costs a lot. It's just that the place where the keys are placed, I don't know how much brain cells it will consume. If it weren't for Yang Yuanzhao's pointing it out, he would probably never find the key. The box is too heavy and placed there steadily. No one can touch it, and no one can find it unless it's luck.

The key was right, stuck in the keyhole, tightly sewn, twisted it hard. The clamp spring bounced open quickly, revealing several small poles. He pulled them hard along the poles and pulled them up. The box folded up, revealing everything inside, a small box that was only a few dozen centimeters square. It was filled with small black particles, as fine as sand, and fine and dense, filling the entire box. It was not the gold or silver that Hubi had thought of before. It was not platinum. It was obviously wrong in color. It must be a kind of metal.

Habi is a businessman and has also done business in steel. He is not unfamiliar with various metals. He reaches out and holds a handful of powder in his hand. The first feeling is that it is heavy, heavy, and a little bit of a handful of metal. If it is replaced with steel, it will not be too heavy. However, this metal is extremely heavy, and obviously the proportion is far above steel.

I pinched it hard. It was very hard, unlike a simple metal. I silently calculated the volume of the box. When I asked the porter about the feeling, I roughly got the weight, combined with the weight and volume of such a box. Habi quickly calculated it. The specific gravity of this metal is at least more than 16, or even more, such metals. There are not many on the entire periodic table of elements, which remind me of the shape, color and hardness of the metal in front of me.

Tungsten? Could it be tungsten? Hubi's eyes finally fell on this tungsten powder. He couldn't believe it was tungsten. Obviously, looking at the appearance of these tungsten, they were pure metal tungsten, neatly placed in the box, and they looked very good and looked very high-end. These were all hundreds of boxes, and they were probably a lot.

Habi is an ordinary businessman. As a Jew, he is well-informed and is very clear that the recent role of tungsten seems to be related to a military industry achievement. What he inquired before was that the price of tungsten per ton is an astronomical figure, and the price per ton should be between 400,000 marks and 500,000 marks, and the fluctuations are quite severe.

No wonder Yang Yuanzhao took this metal as the focus of this ocean-going transaction. I am afraid that other whole ships, together, are not as expensive as tungsten. In terms of value, the value of tungsten cannot be compared with gold, and is also an important precious metal. The most important thing is its performance, which plays a huge and necessary role in gun steel, ship deck, and protective armor. Especially recently, many German scholars have continuously achieved results in the research of tungsten alloys. Based on his gun steel, the performance of traditional gun steel is at least two layers higher in all aspects. For heavy guns, the performance indicators have been improved very rapidly, and tungsten was immediately sought after and is known as one of Germany's most important military masterpieces.

It was at this time that Germany strengthened its collection of black stones. Not only did the rituals and foreign companies, they arranged a large number of personnel to go directly to the black stone production area in Jiangxi and purchase black stones at high prices. Seeing this in Germany, other countries also began to notice the black market and the prices of cheap black stones continued to rise like somersaults.

Habi was a steady man. He immediately looked for other boxes and brought five more boxes. He found the keys at that location and opened all the boxes. Each box was filled with the same powder. He immediately understood what Yang Yuanzhao meant. It turned out that Yang Yuanzhao had never placed all his hopes on him. Maybe there was, but more of them were still here. If these things were really tungsten, then this thing not only represented a huge wealth that was shocking, but also a huge influence.

Habi calmly restored the boxes to their original state. In one of them, he took out a small handful of them and packed them in small bottles. He ordered his staff to focus on keeping them, so that they could be foolproof, and then put down everything and headed to Hamburg City.

Hamburg, as the largest port in Germany, has many science and engineering universities. Because of the Chinese people's schooling, they have been rejected by a large number of universities. Habi has left a trace of Chinese students in the university circle. After all, a generous and rich chamber of commerce has supported many science and engineering majors. However, 1.5 million marks have been spilled in the universities in Hamburg, and the most famous Hamburg University directly invested 250,000 yuan. Without involving the fundamentals of the school, it can be treated with considerable courtesy.

Under such circumstances, Habi easily met Professor Fisher, the professor of the Department of Metallurgy at the University of Hamburg, and the deputy director of the Department of Metallurgy, and the doctoral supervisor. He has extremely profound attainments in the fields of metals and alloys. He is the top ten in the field of metallurgy in Germany. In short, he is an outstanding metallurgical expert.

"Professor Fisher, I'm very happy to see you!" Seeing Professor Fisher come out in person, he had conducted a survey on many universities in Germany before, and the University of Hamburg is one of them. He has also heard of Professor Fisher's name, so he has a very sincere attitude.

"Mr. Habi, thank you very much for your support to our school and the Metallurgy Department. I wonder if I can help you?"

"That's right, Professor Fisher, I have some metal particles here, I want to ask you to make an identification!" Hubby took out a small bottle and handed it to Fisher.

Fisher frowned, and a hint of unhappiness appeared on his face. He thought that Habi was doing something, but found that Habi just wanted him to analyze the materials and analyze what the material was. Not to mention that he was a professor, even an assistant on the side could do it. Fisher was unhappy, but he took it over. He was a little bit of a small matter. He donated 70,000 marks to the University Metallurgy Department for Habi, and he did it casually, without wasting much time.

Open the small bottle and smell it. It doesn’t have much smell. It is a pure metal, powdery, black, and looks very ordinary. Many metals are of this color. Some of them are poured out from the palm of their hand. Fisher moved slightly. The specific gravity is not light. The metals with a large specific gravity are all good metals. They are additives among many alloy materials. They can improve alloy materials and are the focus of their metallurgy research.

It was heavy in his hand, and it was extremely hard and had no technical analysis. It just looked at the appearance simply. Fisher was stunned. As a professional, he almost instantly thought that this metal might be tungsten.

Tungsten, however, is a relatively popular element in the German metallurgical world in this era. Tungsten is the metal with the highest melting point in nature, with a melting point of 3380 degrees, which makes it a natural high-temperature resistant material, and has always been moving in that direction. Some time ago, alloys about tungsten began to become popular, with high temperature resistance, compressive resistance, and wear resistance. These things are extremely important qualities in the military industry. Alloys about tungsten also emerged like mushrooms after a rain. With the surge in usage, the value of tungsten has also been valued. Alloys about tungsten have risen one after another and soared.

In itself, tungsten is a high-priced metal, natural tungsten ore, rarely has a high content of one percent. In addition, the refining of tungsten is extremely difficult, the melting point is extremely high, and it cannot be used. The refining is very difficult, so the price is very high.

Since I had thought about it, I looked at the powder in my hand. It seemed that it was pure texture and seemed to be tungsten with high purity. Fisher suddenly became interested and called a few assistants to help. He entered the laboratory. In the metallurgical laboratory, various German most advanced machines, and after conducting a series of measurements, from chemistry to physics, Fisher finally determined that the powders in front of me were nothing else, pure metal tungsten. It has a very high purity and is very fine and well-in-place powdering. It is an excellent alloy additive material. It can be used directly without deep processing.

It is too unusual for an ordinary chamber of commerce to get so much tungsten. It has done something that many large smelting companies have not done. As a metallurgical expert, Fisher is very clear that the reason why the price of tungsten remains high is on the one hand because it is high in itself. On the other hand, it is because of the extremely difficult and wasteful purification, coupled with the consumption of energy, machines, labor, etc., which has caused it to be expensive enough to attract people's attention.

If we look at this aspect, this so-called virtue and beauty is definitely not a simple enterprise, and Fisher even has a sense of re-understanding of this enterprise.
