Copper has excellent cutting performance, high strength, easy welding and corrosion resistance. During the CNC machining process, the structure is very stable, difficult to be affected by force. And it is usually used in connection parts, vault, stem bearing and so on. Beside copper has good electrical and thermal conductivity, so CNC machining copper prototype is often used in the cover of radiator and the parts of bellows, wave-guide, door, and lamps. And the durability makes the copper become the first choice for most jigs and fixtures.
The deposit of copper in earth is abundant. And copper is a kind of nonferrous metal that relates closely with humankind, with good electrical conductivity, thermal conductivity, extensibility, corrosion resistance and abrasive resistance. CNC machining copper parts are used widely in all walks of life, like electricity, electronics, energy, petrochemical, mechanics, metallurgy, automobile and emerging industries. In China, the consumption of copper is only second to aluminum.
As a diversified metal, copper can meet the unique demand of various products, producing more suitable jigs and fixtures of the products’ tensile test. The main materials of high precision copper jigs and fixtures are copper and copper alloy rod. They perform good in electrical and thermal conduction, and their electrical and thermal conductivity are only second to silver.
