Abstract

PURPOSE: To provide an inexpensive exterior decorative part material for a watch with high tensile strength by preparing a Cu alloy from Cu, Zn and Si in a specified ratio.
CONSTITUTION: A Cu alloy consisting of 8W20wt% Zn, 2W7wt% Si and the balance Cu is prepared. This material is about 1.2 times as high as conventional German silver in tensile strength, and since no Ni is contained, it is equal to brass in material cost, resulting in a considerably reduced cost. In addition, the low Zn content gives high stress corrosion crack resistance comparable to that of German silver.
