Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 8738-2006 "cast zinc alloy ingots." This standard compared with GB/T 8738-2006, major changes
as follows.
--- Remove the "directory";
--- Modified ZnAl4Cu0.4 grade ingredients;
--- Increased billets physical specifications;
--- Increase grades ZnAl17Cu4;
--- Increasing the arbitration analysis method with zinc alloy ingot casting nickel;
--- Added Appendix A.
The standard reference used EN1774.1997 "zinc and zinc alloy zinc alloy ingot casting and casting liquid" in grades 7 and of
Chemical composition.
This standard EN1774.1997 compared to the main changes are as follows.
--- The ZnAl4, ZnAl4Cu1, Al content ZnAl4Cu3 three grades by between 3.8% and 4.2% revised to 3.9% ~ 4.3%;
Mg levels ranging from 0.035% to 0.06% revised to 0.03% ~ 0.06%; Cu content ZnAl4Cu3 grades of from 2.6%
3.1% revised to 2.7% ~ 3.3%; canceled the three grades of Si requirements;
--- The corresponding foundry industry in China GB/T 1175-1997 "cast zinc alloy" in grades, this standard also uses the standard
ZnAl9Cu2Mg, ZnAl11Cu5Mg two grades (to improve the chemical composition of some impurities content requirements).
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard was drafted. Zhuzhou Smelter Group Co., Ltd., Guangdong Jinyi Alloy Products Co., Ltd., Shenzhen Lingnan Nonferrous
Metal Co., Promod (Xiamen) Industrial Co., Ltd.
The main drafters of this standard. Tan Yi-Wen, Yang Feng, Jiang Qing, Liu Liqun, Qiushou Hua Yang Lian Jun, Luo Kun, Zhao Xingwei, Hu Zhenqing, Zhang Jian.
This standard replaces the standards previously issued as follows.
--- GB/T 8738-1988, GB/T 8738-2006;
--- YB785-1975.
