H62 brass that average 62% copper content the ordinary brass band, the first letter of the H-Chinese character for "yellow" phonetic alphabet, 62 - Copper in average content; ordinary brass Other elements of the copper alloy, said special brass, is still "H" represents the later with other added elements chemical symbols and the average constituent, such as H62 for the copper content of 60.5% to 63.5%, the balance being zinc content; HAl59-3-2 indicates that its copper content of 57% to 60%, an aluminum content of 2.5% to 3.5%, a nickel content of 2% to 3%, the rest for the zinc content. Brass divided into ordinary brass, special brass and cast brass three cast brass after to ZCu the beginning with the other elements in the symbols and their average levels of. Chemical composition of the copper (Cu): 60.5 to 63.5% iron (Fe): ≤ 0.15% lead (Pb): ≤ 0.08% antimony (Sb): ≤ 0.005% bismuth (Bi): ≤ 0.002% phosphorus (P): ≤ 0.01 % zinc (Zn): sum of margin impurities: ≤ 0.5% features ordinary brass, good mechanical properties, thermal state plastic, cold plastic can also be cutting good, easy brazing and welding, corrosion , but prone to corrosion cracking. Moreover the price is cheap, it is widely used an ordinary brass varieties. The H62 (forty-six brass). Compared with the α phase at room temperature β much harder, and thus can be used to bear a greater load parts. α + β two-phase brass above 600 ℃ thermal processing. microstructure of α + β two-phase brass: α as a bright white solid solution, and β is an ordered solid solution of CuZn-based. Strong electric field of high temperature deformation of H62 brass empty inhibition. Use to do all kinds of deep drawing and bending force parts manufacturing, such as pins, rivets, washers, nuts, conduit, barometer spring, screen, radiator parts. Mechanical properties of tensile strength: ≥ 315 Elongation: ≥ 30 Note: In addition to system lock, bell outside the wire in the wire room temperature tensile mechanical properties of the sample size: diameter> 2.0 to 4.0 heat treatment specification thermal processing temperature of 650 to 850 ℃ annealing temperature of 600 ~ 700 ℃ eliminate the stress of low temperature annealing temperature of 270 ~ 300 ℃. Corresponding grades: Chinese (GB): H62 in the United States (UNS): C28000 Japan (JIS): C2800 Germany (DIN): the CuZn40 International Standard (ISO): CuZn40
