JSHR Light Alloy Technology Corporation owns the core technology of “spray forming” and is a high-tech enterprise in China. The performance of the spray-formed high-performance aluminum alloy produced by the company is at the international advanced level, and the products have been successfully applied to many aircraft compressor series components in the Chinese aerospace industry, moon landing buffer devices, space station core cabin manipulators, and domestic large aircraft C919 wing long truss , Various national projects, vehicle chassis, heavy-duty locomotive axle box pull rods, etc., have made significant contributions to the lightweight of the above products. In addition, spray-formed aluminum-silicon electronic packaging materials are widely used in T/R components of aerospace phased array radars. The company has also successfully developed high-rigidity, light-weight and wear-resistant high-silicon alloys and a lightweight structural material of strategic significance to the country-aluminum-lithium alloy.
Products
Spray forming ultra-high strength aluminum alloy
The ultra-high-strength aluminum alloy manufactured by spray forming can effectively solve the problems of difficult casting, inability to forge, and serious segregation in the traditional technology. It can effectively eliminate macro segregation, make the structure uniform and fine, the grain fine, and improve the degree of alloying. 7055 aluminum alloy is a relatively high-strength alloy among deformed aluminum alloys, commonly known as “ace aluminum alloy”, and is also an ultra-high-strength aluminum alloy with leading comprehensive performance registered in the United States. Various extrusions and forgings prepared from spray-formed 7055 aluminum alloy ingots are widely used, replacing traditional aluminum alloys, alloy steels, titanium alloys and other materials in structural parts, achieving a weight reduction of 20-60%.
Spray forming aluminum-lithium alloy
The ultra-high-strength aluminum alloy manufactured by spray forming can effectively solve the problems of difficult casting, inability to forge, and serious segregation in the traditional technology. It can effectively eliminate macro segregation, make the structure uniform and fine, the grain fine, and improve the degree of alloying. Aluminum-lithium alloy has excellent properties of high strength, high rigidity, and low density, and is an excellent material indispensable for lightweight structure.
Spray forming wear-resistant aluminum alloy
The high-silicon wear-resistant aluminum alloy prepared by spray deposition technology has the characteristics of small and uniform structure, uniform silicon crystal and intermetallic compound phase distribution, and can be extruded, heat-treated and strengthened, and has excellent mechanical processing properties, making high-silicon aluminum alloy materials The potential for superior tribological performance has been developed. The structure of high-silicon wear-resistant aluminum alloy materials contains high-hardness particle phases such as primary silicon and intermetallic compound phases. The finer these hard-point phases are, the more uniform the distribution, and the better the tribological performance; primary silicon content and transition alloy elements The higher the content, the more beneficial the tribological performance and high temperature performance. The ideal tribological surface has high hardness particles protruding, and the surrounding soft matrix forms pits. When friction occurs, the hard point phase plays the role of bearing force and wear resistance, and the surrounding pits have the functions of oil storage, lubrication and heat insulation.
Spray forming aluminum silicon alloy
The aluminum-silicon alloy prepared by spray forming is an excellent electronic packaging material, and high-silicon aluminum alloy materials with different properties can be obtained by adjusting the volume fraction of silicon. It has a low thermal expansion coefficient, low density, high thermal conductivity, and electrical conductivity. Good performance (with excellent electromagnetic interference / radio frequency interference shielding performance), high hardness, excellent thermo-mechanical stability, high compactness, easy machining, easy plating protection, compatibility with standard microelectronic assembly processes, etc.
Customize high performance alloys
Spray forming technology can effectively solve the problems of low performance and serious performance dispersion of existing alloys, and customize various alloy formulations according to customer needs.
