Copper is a highly reactive base metal. Exposure to oxygen, moisture, and human sweat triggers a chemical reaction called oxidation. This process creates a patina, altering the surface color of the metal to brown, black, or green.
Sourcing pure copper jewelry presents significant quality control challenges for retail brands. The rapid oxidation rate leads to accelerated tarnishing. The chemical reaction between copper and human sweat often leaves a green residue on the skin of the consumer. These physical limitations increase customer complaints and reduce the overall product lifecycle value.
Retail brands frequently utilize brass as a superior structural alternative for fashion collections. Brass is a metallurgical alloy composed primarily of copper and zinc. The addition of zinc increases the tensile strength of the material and improves its baseline resistance to immediate oxidation. Premium brass serves as an optimal substrate for advanced electroplating and surface treatment processes.
