MACHINABLE LEAD-FREE FORGING COPPER-CONTAINING ALLOY

摘要

PURPOSE: To retain the hot workability of a lead-free two phase copper-contg. alloy contg. 'forging' brass and 'architectural' bronze. ;CONSTITUTION: A two phase α+β brass is made free of lead while its hot workability is particularly retained. By feeding bismuth instead of lead together with either of elemental phosphorus or indium, the hot workability appendant to the conventional lead-contg. 'forging' and 'architectural' brass can securely be assured.;COPYRIGHT: (C)1994,JPO
