What are the ways to identify pure copper
1. Check the hardness: the higher the fineness of copper jewelry, the softer the texture and the whiter and smoother the surface. Copper alloy manufacturers take copper bracelets of about 60 grams as an example. If they are pulled open by hand, there is no elasticity, and their fineness is about ...Read more -
