What is H62 brass?
H62 environmentally friendly brass strip is a brass alloy material with copper and zinc as the main components. The copper content is 60.5%~63.5%, with zinc as the balance, iron ≤0.15%, and lead ≤0.08%, conforming to GB/T 2059-2000 standard. This material has good mechanical properties, excellent plasticity in the hot state (650~850℃), and can be deeply drawn in the cold state. It also has good machinability, weldability, and resistance to general corrosion. Physical states include soft, semi-hard, hard, and O-state.
High-precision strips with a thickness ≥0.05mm can be produced, with specifications covering a thickness range of 0.15~3mm, and slitting is supported. Performance is optimized through annealing (600~700℃), making it suitable for manufacturing load-bearing parts such as pins, rivets, washers, nuts, and pressure gauge springs. It is used in electrical and electronic applications, marine equipment, radiator components, and other heat and electricity conductive applications.
