Chrome bronze alloy for aviation
With the rapid development of modern aviation and aerospace, higher requirements have been put on the comprehensive properties of high-strength and high-conductivity copper alloys. Aerospace chrome bronze alloy is the material of the inner wall of the thrust chamber of a large thrust rocket engine.
High-performance copper alloy
With the rapid development of the defense industry, high-performance copper alloys for aerospace use have been widely used for their advantages such as high electrical conductivity, good thermal conductivity, high strength, and easy processing. Adding Cr, Zr, Ag and other elements to the copper alloy can improve its heat resistance, oxidation resistance, wear resistance and tensile strength. Aerospace chrome bronze is the material of the inner wall of the thrust chamber of the rocket engine. Because it is subjected to harsh environments such as high temperature and high pressure during work, it is required that the material has good plasticity and high thermal conductivity. At the same time, it requires compact structure, fine grains, Inclusions, delamination, segregation and other defects.
Applications
Aviation rocket engines, motor commutators, and others require high strength, hardness, electrical conductivity and thermal conductivity at high temperatures.
Spot welding, roll welding machine electrodes, etc.
Resistance welding parts and high-conductivity, high-strength electrodes
Resistance welding parts and high-conductivity, high-strength electrodes
Rocket Engine Parts
ZZQY Alloy Technology Co., Ltd. independently researches and develops chrome bronze (QCr0.8) ingots, forged rods, extruded rods for rocket engines for aerospace, and also develops Cu-Cr50, a vacuum switch contact material. The tensile strength is 230 ~ 400MPa, the yield strength is 100 ~ 300MPa, the elongation is 30 ~ 40%, and the electrical conductivity is 89 ~ 93% IACS. The performance is much better than the national standard. Our company adopts advanced melting and casting technology, and at the same time adds Cr element in the way of adding intermediate alloy to ensure that the internal structure of the alloy is uniform and consistent. The chrome bronze alloy developed by our company has passed the tests of relevant aerospace, military and other units.
