Material Name: H62 brass plate, C2680 brass plate Grade: H62 (C2600) Standard: GB / T 5231-2001 H62 brass represents an average copper content of 62% of the ordinary brass, joined in on the basis of ordinary brass Copper alloys other elements called special brass, still "H", said back will add other elements with chemical symbols and the average composition, such as H62 for copper content of 60.5% ~ 63.5%, brass is divided into ordinary brass Special three brass and cast brass, cast brass ZCu beginning to back with the other elements of symbols and their average content. (1) Ordinary Brass is a binary alloy of copper and zinc. As the plastic, suitable for manufacturing sheet, rod, wire, pipe and deep drawing parts, such as the condenser, heat pipes and machinery, electrical parts. The average copper content of 62% and 59% of the brass can also be cast, as cast brass. (2) Special brass in order to obtain higher strength, corrosion resistance and good casting properties, adding aluminum, silicon, manganese, lead, tin and other elements in the alloy of copper and zinc to form a special brass. Such as lead, brass, tin, brass, aluminum, brass, silicon brass, manganese brass. (3) Special brass in α and β phase solid solution phase is diverse and complex, the larger its strengthening effect, while the average of the α and β brass with a simple Cu-Zn solid solution strengthening effect lower, these can be The data listed in Table 5 were seen. Although zinc equivalent rather, multiple solid solution with a simple circle, nuts, conduits, barometer spring, screen, radiator parts. Mechanical Properties: Tensile strength: ≥315 Elongation: ≥30 Note: In addition to lock, bell wire with another wire outside temperature tensile mechanical properties of the sample size: diameter> 2.0 to 4.0 specification heat thermal processing temperature of 650 ~ 850 ℃ annealing temperature of 600 ~ 700 ℃ to eliminate the stress of low temperature annealing temperature of 270 ~ 300 ℃.
