Product Detail H62 brass is an ordinary brass with an average copper content of 62%. It has good mechanical properties, good plasticity in hot state and cold state, good machinability, easy brazing and welding, corrosion resistance, but easy to produce corrosion cracking. In addition, the price is cheap, and it is an ordinary brass variety widely used. H62 (i.e. four or six brass). At room temperature β Compare α The phase is much harder, so it can be used for parts bearing large loads. α+β Two phase brass can be hot worked above 600 â??. α+β Microstructure of two-phase brass: α It is a bright white solid solution, β It is an ordered solid solution based on CuZn. The inhibition effect of strong electric field on the spatiotemporal cavity of H62 brass during high temperature deformation. chemical composition Copper (Cu): 60.5 ~ 63.5% Iron (FE): ≤ 0.15% Lead (PB): ≤ 0.08% Antimony (sb): ≤ 0.005% Bismuth (BI): ≤ 0.002% Phosphorus (P): ≤ 0.01% Zinc (Zn): surplus Total impurities: ≤ 0.5% Application: it can be used as various stressed parts made by deep stretching and bending, such as pins, rivets, washers, nuts, conduits, barometer springs, screens, radiator parts, etc. Mechanical properties: Tensile strength: ≥ 315 Elongation: ≥ 30 Note: tensile mechanical properties at room temperature of other wires except those for lock and clock making Heat treatment specification: Hot working temperature 650 ~ 850 Annealing temperature 600 ~ 700 The low-temperature annealing temperature for eliminating internal stress is 270 ~ 300 Specifications and dimensions can be customized according to your requirements.
