Standards

Name Code Standards
Castings, non-ferrous metals and alloys В84 OST 5Р.9209-82

Chemical composition

Standard P Fe Cu Zn Sn Sb Pb Bi
OST 5Р.9209-82 ≤0.01 ≤1 88-91 Rest ≤0.5 ≤0.1 ≤0.5 ≤0.003
Zn is the basis.
According to OST 5P.9209-82, the total percentage of impurities should be ≤ 1.5%. Impurities not specified are taken into account in the total amount of impurities. As agreed by the manufacturer with the consumer, the silicon content is allowed to be no more than 0.30% due to the copper content for improving the fluidity, and to 0.50% for the manufacture of parts not subjected to welding. In castings subject to welding, it is recommended to limit lead content to 0.030%, and antimony up to 0.0050%.
