Aluminum bronze, specifically with an aluminum content of above 11.5% and below 15%, exhibits commendable performance. Its elemental composition, apart from aluminum, closely resembles that of regular aluminum bronze. The disparity in aluminum concentration endows special aluminum bronze with heightened strength, comparable to that of alloy steel, and approaches the hardness of alloy steel as well. Consequently, this material finds widespread application in various force structure parts and transmission components. Moreover, its exceptional corrosion resistance, compression resistance, and wear resistance make it an ideal choice for high-speed train transmission shaft gears. Regarded as the epitome of excellence within the realm of copper alloys, aluminum bronze boasts an array of superior physical, chemical, and mechanical properties. These include optimal strength, elasticity, hardness, fatigue strength, minimal elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetism, and spark-free impact.
