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. In this standard, the elemental content of ZCuSn10P1 copper alloy is revised. The adjustment of this grade of chemical composition is based on the accumulation of many years of production experience. In the production practice, it was found that the P element in the ZCuSn10P1 copper alloy has a stable performance in the range of 0.8% to 1.1%. Based on this, the P content is adjusted from 0.5% to 1.0% to 0.8% to 1.1%, while the Sn content is still 9.0. %~11.5%.

Centrifugally cast ZCuSn10P1 copper alloy mechanical properties (room temperature environment), tensile strength Rm/MPa ≥ 330, yield strength Rp0.2/MPa ≥ 170, elongation A% ≥ 4, hardness HBW ≥ 90 °.

The materials of ZCuSn10P1 tin bronze sleeves corresponding to foreign brands are: American Standard No. C90700, British No. PB4, Japanese No. PBC2B and International Standard CuSn10P.

  Hunan Jintai Hardware and Machinery Co., Ltd. is a professional manufacturer of ZCuSn10P1 copper alloys and other grades of copper alloy products. 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.
