The latest standard of High sthrength brass chemical composition
2018-05-30
As one of the basic performance standards for casting, the issuance of the national standard GB/T 1176-2013 «Casting copper and copper alloy» is a significant event in the foundry copper alloy industry. ZCuZn25Al6Fe3Mn3 copper alloy is commonly called Gaoli Brass. In this version of the standard, the chemical composition of Mn and Fe in Gaoli Brass was adjusted. In the new standard, the contents of each element are as follows: Cu 60%~66%, Al 4.5%~7.0%, Mn2.0%~4.0, Fe2.0%~4.0.
High strength brass mechanical properties (room temperature environment), tensile strength Rm/MPa ≥ 740, yield strength Rp0.2/MPa ≥ 400, elongation A% ≥ 7, hardness HBW ≥ 170°.
Hunan Jintai Hardware and Machinery Co., Ltd. is a professional manufacturer of various grades of copper alloy products such as national standard ZCuZn25Al6Fe3Mn3 high strength brass. The company regularly requests authoritative third-party testing agencies to conduct chemical composition analysis and mechanical property testing of the company's products to ensure that product quality meets the requirements of national standards.
