What is Copper fasteners?
Copper fasteners are specialized hardware components designed for applications requiring excellent electrical conductivity, thermal resistance, and corrosion protection. Made from high-purity copper or copper alloys (such as brass or bronze), these fasteners are ideal for electrical systems, marine environments, HVAC, and industrial machinery.
