Abstract:
This free-cutting copper alloy casting contains 75.0-78.5% Cu, 2.95-3.55% Si, 0.07-0.28% Sn, 0.06-0.14% P, 0.022-0.20% Pb, with the remainder being made up of Zn and unavoidable impurities. The composition satisfies the following relations: 76.2≤f1=Cu+0.8×Si−8.5×Sn+P+0.5×Pb≤80.3, 61.2≤f2=Cu−4.4×Si−0.8×Sn−P+0.5×Pb≤62.8. The area ratios (%) of the constituent phases satisfy the following relations: 2.5≤κ65, 0≤γ≤2.0, 0≤β≤0.3, 0≤μ≤2.0, 96.5≤f3=α+κ, 99.2≤f4=α+κ+γ+μ, 0≤f6=γ+μ≤3.0, 29≤f6=κ+6×γ 1/2 +0.5×μ≤66. The long side of the γ phase does not exceed 50 μm, the long side of the μ phase does not exceed 25 μm, and the κ phase is present within the α phase.

Claim (Index 9):
