CuZn40Al2 High Tensile Brass Bushing,

CuZn40Al2, 2.0550, SoMs58Al2

is a robust brass alloy favored for manufacturing bushings due to its notable tensile strength, dense and even structure, alongside excellent resistance to corrosion. This hot workable alloy is well-suited for a range of uses, including gears, wear plates, chain guides, shafts, and bushings, thanks to its blend of high strength and corrosion resistance. The alloy consists of 57-59% copper (Cu), 1.3-2.3% aluminum (Al), and up to 1.0% iron (Fe), with zinc (Zn) making up the bulk of the remaining composition, alongside trace amounts of other elements. With a tensile strength of around 540 N/mm^2 and a hardness level of 160 HB, it’s engineered for demanding applications needing durability and strength. Bushings crafted from CuZn40Al2 find applications across various sectors, particularly in automotive and hydraulic systems, where they excel in high load, low speed scenarios. It’s crucial to remember that factors such as cost, availability, and specific characteristics of these high tensile brass bushings might differ depending on the manufacturer and the precise needs of the application.
