Abstract

PURPOSE: To provide an exterior decorative part material for casting having high strength and causing no stress corrosion cracking by preparing a Cu alloy consisting of Cu, Zn, Si and Ni in a specified ratio.
CONSTITUTION: A Cu alloy consisting of 8W20% Zn, 1W7% Si, 1W6% Ni and the balance Cu is prepared. This material is about 3 times as high as conventional brass in tensile strength and about twice in hardness. Because of the low Zn content dezincing phenomenon and stress corrosion cracking do not occur, and the addition of Si increases the strength of the alloy furthermore.
