Answer Hello, I am glad to answer the questions for you. Copper alloy is not gold or 999 full gold. Copper alloy is simply a substance composed of two or more metals. Copper alloy jewelry is generally made of brass, and the surface electroptoling is 24K gold. Copper is not easy to oxidize and can maintain the gloss and brightness of gold for a long time, so it is loved by consumers. Because the color is similar to gold jewelry, it is often used by illegal merchants to use brass to fake gold jewelry.
Copper alloy is not gold. The copper alloy is a alloy composed of one or several other elements with pure copper as the base. It to make electric equipment such as generators, home cables, cables, switching devices, transformers, and heat exchangers, pipelines, solar heating devices such as tablet collectors and other heat conductors. Common copper alloys are divided into three categories: brass, bronze, and white copper. Casting process The crystalline characteristics of copper alloys of various ingredients are different, the casting performance is different, and the casting process characteristics are different.
1, tin bronze: Crystal characteristics are large crystalline temperature range and width of the solidified area. Founding performance is poor in liquidity, which is prone to shrinking and not easy to oxidize. The craftsmanship is that the wall thickness parts adopt directional solidification (sequential solidification). 2, aluminum bronze and aluminum brass: Crystal features are small crystal temperature range, which is a layered solidification feature. The casting performance is better, which is easy to form a concentrated shrinkage, which is easy to oxidize. The craftsmanship is that the aluminum and bronze pouring system is a bottom -out system, and the aluminum brass pouring system is open.

What you asked is ridiculous, then I tell you that it is gold, do you take it seriously?
