Copper Fasteners

About Copper Fasteners

Copper is a chemical element that is soft, malleable, and ductile in nature. It also has a very high electrical and thermal conductivity which makes it be used in different applications of electrical usage. Copper is used as a conductor of heat and electricity. It is among the few metals that can occur in nature in a directly usable metallic form. It is also considered the best key constituent of the respiratory enzyme complex.

Copper Fasteners are widely used in electrical applications in the core processing industries. Fasteners are also used in the marine and corrosive environments; they are also used in medical equipment because of its effective features. Fasteners also contain various characteristics same as the copper-
» Stable in high temperatures
» Corrosion resistance
» Good moldability
» High weldability
» Durable
» High tensile strength
