The reason why Zhuang Jianye has such self-confidence is that, in addition to the cost reasons mentioned above, another key factor is also the basis for determining everything, that is, China Ascendas has mastered a large number of advanced technologies and leading process manufacturing capabilities.

This is the fundamental reason why the cost of Diamond Monkey-2C is so low.

The T-NB525 aluminum-lithium alloy used by China has benefited from China’s accumulation in this field for many years. It has not only formed a complete industrial chain, but also relied on superior technology and experience to make the price of this category of materials more than ten years old. A reduction of 60% within the year.

Not only has the European aluminum industry, which is fully supported by Europe, completely killed, but also Europe has no say in the key aviation and aerospace materials of aluminum-lithium alloy; it also puts the North American aluminum industry in the United States under tremendous pressure and has suffered losses for years. , Hard support.

As for the aluminum-lithium alloy industries in Japan and Russia, they are basically wiped out by China's soaring aluminum-lithium alloys.

The reason why China takes off from a prince to the ultimate overlord in aluminum-lithium alloys is mainly due to the in-depth development of rare earths.

As early as the mid-1990s, China Ascendas had already entered the field of rare earths. At that time, the domestic rare earth industry chain was still very backward, basically similar to the big dog owners in the Middle East. They mined the mines and sold them.

What kind of deep processing does not exist at all, so that it has endured the exploitation of foreign scissors for a long time.

With the domestic opening of the rare earth technology field to a group of powerful high-tech companies such as China Ascendas, the situation began to change. Take China Ascendas as an example. After more than ten years of development, China Ascendas has mastered the development of rare earth mining, Smelting and separation until it becomes the complete industrial chain of the final industrial product.

The semi-finished rare earth products mined and separated each year account for 35.6% of the world's total supply.

In the words of a certain domestic rare earth expert, even if China takes off, even if it does nothing, it can make a lot of money by mining and separating rare earths.

However, with such a high proportion, the semi-finished products provided by China Ascendas to the international market only account for less than 5% of the total.

The rest was digested by other business areas of China Ascendas.

For example, the optical components on China's Ascendas Optical Satellite require a large amount of elements separated from rare earths; there are also rare earths in the semiconductor manufacturing process; as for the aviation and aerospace manufacturing fields, a large amount of rare earths are also needed.

For example, a high-temperature alloy material developed by China Ascendas Aviation Materials Co., Ltd. (Group) in 2003, T-NB359B nickel-based alloy, creatively added cerium separated from rare earths, so that it could only be below minus 20. Ordinary nickel-based alloys between degrees Celsius and 360 degrees Celsius will not only expand the temperature range of minus 230 degrees Celsius to 700 degrees Celsius.

And at a high temperature of 650 degrees Celsius, T-NB359B nickel-based alloy still maintains good fatigue resistance, oxidation resistance, radiation resistance and corrosion resistance. Especially in the key index of yield strength, it is almost the strongest among the same type of materials. One of the.

Because T-NB359B nickel-based alloy has such excellent properties, once it came out, it won large orders from major domestic giants.

Among them, China's nuclear power purchases are the largest, because this alloy material that can still maintain a good condition at high temperatures can be said to be the most ideal material for nuclear power plant reactors.

The purchase of Chinese ships is also a lot, because they are missing such a key material in the nuclear reactors of the new generation of nuclear submarines they built for the Navy.

In the future nuclear-powered aircraft carrier planned by Chinese ships, T-NB359B nickel-based alloy also has an irreplaceable position.

As for China Ascendas itself, it is also a major user of T-NB359B nickel-based alloys, the turbine blades of small aero-engines; the turbine discs and high-pressure turbine blades of medium-sized aero-engines; the turbine shafts of high-thrust aero-engines are all T-NB359B nickel-based alloys. The scope of application.

In addition, T-NB359B nickel-based alloys also have very broad applications in chemical, electric power, petroleum and other fields.

Because of this, there is no opportunity for T-NB359B nickel-based alloys to be exported at all. The country’s several large Chinese companies have given it to Bao Yuaner. This is not enough. Every quarter, several giants will urge China to take off and speed up production. delivery!

Already unpopular nickel-based alloys are the same, not to mention the wider application range of aluminum-lithium alloys. As early as the end of the nineties, China Ascendas began to try to add rare earth elements to aluminum-lithium alloys to improve aluminum-lithium alloys. Various properties.

For example, China Ascendas tried to incorporate the anti-elements extracted from rare earths into the aluminum-lithium alloy to make it have better weldability and excellent heat treatment characteristics.

And this is just a basic aluminum-lithium alloy disclosed by China Ascendas.

Similar to the T-NB525 aluminum-lithium alloy used on the Diamond Monkey-2C carrier rocket, the description file only marked the application of rare earth elements. What is the specific content, and the content is not at all.

China Ascendas has three similar aluminum-lithium alloy grades, and different grades of aluminum-lithium alloy can be used according to different product application scenarios.

For example, the T-NB515 series aluminum-lithium alloy used in aircraft skins highlights the processing ability; another example is the T-NB545 series aluminum-lithium alloy used in aircraft truss beams, which highlights the yield and tolerance; and cruise The T-NB535 series aluminum-lithium alloy used on the missile is outstandingly cheap.

The T-NB525 series of aluminum-lithium alloys are more like a combination of the above four types, not only the cost is low, the processing ability is strong, but also the yield strength and endurance are extremely strong.

Of course, in addition to high-level materials, advanced processing technology is also indispensable. In this regard, China’s take-off can be said to be the leading trend. When the T-NB525 series aluminum-lithium alloy leaves the factory, the inner surface has its own special reinforcing rib grid. .

This technology is currently in the hands of China Tengfei, except for the North American aluminum industry in the United States.

As for other manufacturers, they can only give you a whiteboard made of aluminum-lithium alloy. You can only buy what kind of reinforcement you want and engrave it yourself.

However, China Ascendas uses its own chemical milling process to complete this step before the material leaves the factory.

That's not to say, because of its precise milling and washing, others can't imitate it even if they want to imitate it. UU Reading www.uukanshu.com is very sophisticated because of the very sophisticated crafting ratio, and the whole material will not be scrapped even if it is slightly inferior.

Such semi-finished parts only need to be cut quickly on the outer surface after they get to the processing plant, and the thinnest can be 1.5 mm, without worrying about material strength, because the special grid reinforcement ribs on the north side are already strong enough.

The thickness of the hydrogen fuel storage tank of the Diamond Monkey-2C is 2.5 mm, and the T-NB525 aluminum-lithium alloy used in the rocket body is only 4.5 mm. The overall quality is not high.

However, if you want to do this, you can't do it in any country. You have to know that 4.5 mm thick metal is basically the same as paper. Hell level.

However, the T-NB525 series of aluminum-lithium alloys produced by Ascendas in China can be achieved. There is no way. In addition to the excellent material itself, the excellent chemical milling process is also indispensable. The Russians are now even the chemical milling left over from the Soviet era. The dumb Kaka who is playing in the washing, the higher level of chemical milling, even the door is not touched, under such conditions, if you want to copy, you can only say that it is a dream!
