The materials of metal connectors mainly include the following:
Pure copper: Pure copper has good electrical conductivity and thermal conductivity. It is often used to manufacture connector pins and sockets, which can effectively reduce the loss in signal transmission and power transmission.
Copper alloy:
Brass: Brass is an alloy of copper and zinc. Its mechanical properties are better than pure copper. It is relatively cheap and is often used in occasions where conductivity is not required, such as ordinary power connectors.
Phosphor bronze: A phosphorus-containing copper-tin alloy with good elasticity and wear resistance, suitable for connectors that are frequently plugged and unplugged, such as the reed of a USB interface.
Beryllium bronze: An alloy containing beryllium, with high strength, high hardness and good corrosion resistance, suitable for high-end connectors or connectors used in harsh environments.
Stainless steel: Due to its excellent corrosion resistance and mechanical properties, it is widely used in the manufacture of connector pins and sockets, especially in harsh environments such as outdoor or industrial environments.
Aluminum: Aluminum has good electrical conductivity and mechanical properties, making it suitable for certain types of connectors.
