8MM 12mm 10mm Copper Earthing Rod C1020 C10200

C1020 C10200 Copper Alloy Rod Bar For Building Construction

Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create bronze, c. 3500 BC.

C10200 has conductivity 101% IACS, the highest among coppers. Used for electrical and electronic conductors, wave guides, cavity resonators, superconductor matrixes, vacuum tube and solid-state devices, and glass-to-metal seals. The machinability rating of this alloy is 20.

Copper 102 is an oxygen-free copper with extremely high electrical conductivity and good formability. These characteristics make it particularly useful for electrical connectors. Copper 102 can be deep-drawn from the annealed temper.It is corrosion resistant in normal atmosphere and water.
