Grade: C2801 C2801 features: ordinary brass, with good mechanical properties, thermal state plastic good, plastic is also cold, cutting, easy brazing and welding, corrosion resistance, but easy to produce corrosion cracking. Also cheap, widely used a variety of ordinary brass. At room temperature, compared to α β phase much harder, and thus can be used to bear a greater load of parts. α + β two-phase brass at above 600 ℃ thermal processing. α + β brass two-phase microstructure: α as a bright white solid solution, β is ordered CuZn-based solid solution. C2801 uses: do all kinds of deep drawing and bending of the force components, such as pins, rivets, washers, nuts, catheters, barometer spring, screen, radiator parts. Mechanical properties: Tensile strength (Rm N/mm2): 385.0 Elongation (A%): 15.0 C2801 chemical composition Cu :60.5-63 .5 Ni: 0.5 Fe: 0.15 Pb: 0.08 Zn: residual impurities: 0.5 C2801 mechanics properties Tensile strength: (σb / MPa) 410-630 Elongation: (δ10 /%) ≥ 10 Vickers hardness: (HV) 105-175 (thickness ≥ 0.3) Note: the thickness 0.3-10
