I don't know when we started researching aluminum alloy materials used in military or special industries, and we have gained a lot in this process. We have developed and produced various aluminum alloys and extruded materials that are in line with China's national conditions, basically meeting the needs of national defense, military industry, national economic construction, and people's lives.

But what is the relationship between this and powder metallurgy technology? Mainly because there is still a significant gap between the overall level and independent research and development capabilities of aluminum alloy materials and the international advanced level. In order to narrow the gap, powder metallurgy technology plays a crucial role.

To improve traditional aluminum alloy materials, it is necessary to rely on a series of advanced technologies and theories, such as microalloying theory, electronic metallurgy technology, etc. Powder metallurgy technology is included to adjust the content and proportion of alloy elements and add efficient trace elements. At the same time, it is necessary to study the strengthening theory, develop deformation heat treatment processes and new technologies for efficient purification, purification, refinement, and homogenization, in order to achieve the goal of changing traditional aluminum alloys.

Under the operation of various advanced technologies, aluminum alloy materials and extruded products with higher strength, toughness, high modulus, wear resistance, corrosion resistance, fatigue resistance, high temperature resistance, low temperature resistance, radiation resistance, fire resistance, explosion-proof, easy cutting, easy polishing, surface treatment, weldability, and ultra light weight can be developed to meet the needs of different uses, performance, and functions.

However, at the same time, it is necessary to research and develop various aluminum alloy heat treatments, deformation heat treatments, and surface treatments to obtain materials with special properties and functions. Even though the role of powder metallurgy has become a very new concept, it is still necessary to conduct in-depth research on aluminum alloy products such as powder metallurgy, spray forming, composite materials, ultrafine powders, and nanoscale materials, in order to seek greater breakthroughs.
