Bronze Bro3c13s4 (БрОЦС3-13-4)
Designation
Description
Bronze Bro3c13s4 used: for the production of ingots from scrap and waste of nonferrous metals and alloys used as charge material for the manufacture of tin foundry of bronze according to GOST Bro3c12s5 613.
Note
The alloy system Cu-Sn-Zn-Pb.
Standards
Chemical composition
Cu is the basis.
According to GOST 614-97, the total mass fraction of impurities is ≤ 1.30%. The content of arsenic, magnesium, phosphorus and sulfur is determined at the request of the customer. Nickel can be included in the mass fraction of copper - in this case nickel in the sum of impurities is not taken into account. At the request of the consumer, the total amount of impurities of aluminum and silicon should not be more than 0.020%. For parts operating under pressure, the mass fraction of aluminum and silicon can be separately up to 0.050% of each.
