Copper Contact
Copper Contact
Description:Copper is a transition metal element with the following physical properties, high melting point,high hardness,good ductility and low resistivity.Copper contacts are made by stamping,forging and machining of metal copper.They have good electrical and thermal conductivity,good oxidation resistance,strong corrosion resistance,strong mechanical wear resistance,low cost and long service life,and can be recycled,which is the most widely used contact material.
Application:Copper is most commonly used in cables and electrical,electronic and electrical components,and is also used as a building material.Copper contacts are mainly used for movable contacts between circuit breakers and switch cabinet panels.There are generally two types:round contact type and flat contact type.Copper contacts are widely used in household appliances (such as air conditioners and electric kettles),aviation appliances,automotive appliances,relays,thermostats, timers,power plants,cranes and other electromechanical equipment.
FANMETAL also provides high-quality tungsten copper contacts.The addition of tungsten greatly improves the weakness of copper’s easy oxidation in the air, and also enhances the arc corrosion resistance of the composite material.It is a metal material with good performance and durability.
