In all metal elements, copper has the best performance in conductive materials; silver (approx. 1.06 times copper)> copper> gold (approx. 077 times copper) but gold and silver are generally only The use of connector plating materials can reduce the contact resistance, but also increase the whitening and anti-oxidation. The copper metal is low in price and has good conductivity. Therefore, pure copper is used as power, wire, and information in wire and cable. Widely used in transmission, but also in the electronic connector industry for the best choice of material pure copper conductivity is good, but its mechanical strength and heat resistance, not enough to meet the connector industry standards, so you need to add some alloy Elements to improve its own mechanical strength and heat resistance, although the conductivity of pure copper is good, but its mechanical strength and heat resistance, not enough to meet the requirements of electronic connectors, it must add alloy elements to increase its mechanical strength and heat resistance Sex, but because the added metal itself has a specific size of the atom, when added to pure copper, it causes the difference between the atoms and distorts the arrangement of the copper atoms, resulting in weakening during transmission or Resistance. Commonly used in the market are: brass (Cu-Zn); brass (Cu-Sn); white-colored alloy (CU-Ni); but its mechanical strength and heat resistance are better than pure copper.
