Abstract

The invention discloses a corrosion-resistant non-gold imitation-gold alloy with golden color and a preparation process thereof. The alloy consists of the following components in percentage by weight:0.3-0.5wt% of B, 1.2-1.5wt% of Sr, 0.4-0.6wt% of Ti, 0.5-0.8wt% of Mo, 0.4-0.6wt% of Nd, 4.0-6.0wt% of Ge, 8.0-12.0wt% of Zn, 10.0-12.0wt% of Cu and the balance of tin. The invention provides the golden imitation-gold alloy with extremely excellent performance, and types of colorful alloy for jewelry and decorative materials can be greatly enriched.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an imitation gold alloy. Background technique [0002] Human beings have discovered and utilized gold for thousands of years, longer than human written records. Gold was associated with human beings before there was writing, which has been confirmed by more and more unearthed cultural relics. Pure gold jewelry has always been popular among people. This is because pure gold is pure, acid and alkali resistant, durable, and has the highest value. It can fully reflect the owner's wealth, luxury, stability, and loyalty. However, when pure gold is used as an ornament, due to its poor wear resistance, its surface is easily etched and etched when often worn, causing gold loss and affecting the finish of the jewelry. For this reason, by adding other elements such as Ag, Cu, Ni, Pd, Zn, etc. into pure gold to make gold alloy, the strength and wear resistance of gold alloy can be improved ...
