Chromium-molybdenum alloy steel: This is currently the most commonly used material for high-performance ball cages, such as 42CrMo alloy.
Characteristics: It possesses high strength, high-temperature oxidation resistance, and corrosion resistance, with its wear resistance significantly enhanced after undergoing special heat treatment. Advantages: It effectively resists deformation and fracture, extending its service life. It is commonly used in outer cages of high-performance vehicles such as the Audi A6L.
