We can produce whatever weapons we want because our country has developed the highest strength aluminum alloy material in the world.
According to relevant reports, our country has developed an aluminum alloy metal material with the highest tensile strength in the world - 7Y69 aluminum alloy. The main characteristics of this high-strength aluminum alloy metal material are: super wear-resistant , high rigidity, high strength, etc. The performance of 7Y69 aluminum alloy is almost at the same level as ultra-high-strength alloy steel that is three times its weight, which shows the high strength of this high-strength aluminum alloy material. In fact, aluminum alloy is an indispensable material for the aerospace industry due to its low density, high specific strength, good toughness and corrosion resistance. It is also a key research direction in various countries around the world, especially for ultra-high strength aluminum alloys. Research, not only China has invested a lot of money in research, but countries such as the United States and Russia are also conducting vigorous research.
It is worth mentioning that before China developed the 7Y69 aluminum alloy, Japan had maintained the record for the highest aluminum alloy strength in the world. The strength of the aluminum alloy developed in Japan reached 900 MPa, while the 7090 developed in the United States The maximum strength of aluminum alloy is 855 MPa. The maximum strength of aluminum alloy developed in Europe is 840 MPa, which is basically the same. The highest strength aluminum alloy previously reported in China is the injection molded 7055 high-strength aluminum alloy developed by Jiangsu Haoran Injection Forming Alloy Co., Ltd. Tough aluminum alloy with a tensile strength of about 740 MPa. Therefore, from the perspective of strength, China used to lag far behind Japan, the United States and Europe in terms of high-strength aluminum alloy materials. However, now China has developed 7Y69 aluminum alloy, which has completely changed China's backwardness in high-strength aluminum alloy materials.
The 7Y69 aluminum alloy also uses injection molding technology, but in the smelting stage, in addition to adding zinc, magnesium, copper and other metals, appropriate amounts of rare earths and manganese, nickel, titanium and other metal elements are also added, which greatly Enhanced material indicators. According to relevant data, the maximum tensile strength of 7Y69 aluminum alloy is 917 to 957 MPa, and the maximum yield strength is 874 to 895 MPa. Both indicators rank first in the world, surpassing Japan in one fell swoop. Because ultra-high-strength aluminum alloy materials are widely used in the aviation field and even weapons such as missiles, they can have higher strength at the same weight. It is worth mentioning that ultra-high-strength aluminum alloy materials can also be used in the production of fissile materials for nuclear weapons and nuclear power plants.
Previously, the domestically developed 7055 aluminum alloy has been initially used in the aviation sector, mainly in large aircraft projects. We can imagine that if the 7055 aluminum alloy is replaced by 7Y69 aluminum alloy, these products will inevitably It can further reduce weight, greatly increase the range and range, and improve the high-speed performance of the ship. Not only that, because 7Y69 aluminum alloy has extremely strong corrosion resistance, especially to seawater, it can be used as a high-performance ship material. Of course, 7Y69 aluminum alloy can also be used in the weapons industry. In addition to the engine casings of various tactical missiles mentioned earlier, there are also aluminum alloy armor bulletproof materials, lightweight high-strength aluminum alloy material track pads and various light weapons, which greatly enhance Army strength.
