Title:
銅－ニッケル－スズ合金、その製造方法、ならびにその使用法
Document Type and Number:
Japanese Patent JP7097826
Kind Code:
B2
Abstract:
A copper-nickel-tin alloy with excellent castability, hot and cold workability, high resistance to abrasive wear, adhesive wear and fretting wear and improved resistance to corrosion and stress relaxation stability, consisting of (in weight %): 2.0-10.0% Ni, 2.0-10.0% Sn, 0.01-1.5% Si, 0.01-1.0% Fe, 0.002-0.45% B, 0.001-0.15% P, selectively up to a maximum of 2.0% Co, optionally also up to a maximum 2.0% Zn, selectively up to a maximum of 0.25% Pb, the residue being copper and unavoidable impurities. The ratio Si/B of the element contents in wt. % of the elements silicon and boron is a minimum 0.4 and a maximum 8 such that the copper-nickel-tin alloy has Si-containing and B-containing phases, phases of the systems Ni—Si—B, Ni—B, Fe—B, Ni—P, Fe—P, Ni—Si, and other Fe-containing phases, which improve the processing and use properties of the alloy.
