Title:
COPPER BASE ALLOY FOR SLIDING EXCELLENT IN SEIZING RESISTANCE, WEAR RESISTANCE AND CORROSION RESISTANCE
Document Type and Number:
Japanese Patent JPH03215642
Kind Code:
A
Abstract:

PURPOSE: To improve the seizing resistance, wear resistance and corrosion resistance of a copper base alloy under severe sliding conditions by specifying the content of Mn, Si, Zn, Pb, etc., in a Cu base alloy, uniformly dispersing Pb therein and forming the structure of its matrix into a single one.

CONSTITUTION: The compsn. of this copper base alloy for sliding is formed of, by weight, 1.0 to 3.5% Mn, 0.3 to 1.5% Si, 10 to 25% Zn, 5 to 18% Pb and the balance Cu with inevitable impurities. If required, moreover, at least one kind of 0.02 to 1.5% Mg and 0.1 to 1.5% Te or furthermore at least one kind of 0.5 to 3.0% Ni and 0.3 to 3.0% Al are incorporated thereto. Pb is uniformly dispersed into the whole structure as well as the structure of the matrix is formed into a single one of an α phase. The alloy has a performance excellent as a sliding material such as a turbocharger requiring a high performance and a long service life.
