B-505 Copper Alloy Continuous Castings


This specification establishes requirements for continuously cast rod, bar, tube, and shapes produced from copper alloys with nominal compositions. Castings produced to this specification may be manufactured for and supplied from stock. Mechanical tests are required only when specified by the purchaser in the purchase order. Continuous castings shall not be mechanically repaired, plugged, or burned in. Weld repairs may be made at the manufacturer's discretion. For sampling purposes, a lot shall consist of castings of the same composition and same cross-sectional dimensions, produced during the continuous operation of one casting machine, and submitted for inspection at one time unless specified otherwise. The specimen shall be comprised of the following major elements: copper, tin, lead, zinc, iron, aluminum, manganese, and nickel including cobalt. Residual elements may be present in cast copper-base alloys. The fractured bars shall be retained for chemical verification. Both the Brinell hardness reading and Rockwell hardness reading shall be taken on the grip end of the tension test bar. At the request of the purchaser castings shall be marked with the alloy number.
