Electrical contact material of silver matrix capable of resisting arc erosion and containing no cadmium-composite
In an electric contact material of silver matrix capable of resisting arc erosion and containing no cadmium-composite, an Ag—(SnO2+In2O3) composite containing 9˜11% of (SnO2+In2O3) or an Ag—Cu oxide, composite containing 15˜25% of Cu oxide is used. The electrical contact material has a contact resistance of 5˜60 milliohms (mohm) and an arc erosion resistance capability up to 2*103˜10*103 times provided that the Vickers hardness (Hv) of the material is 100˜150, the measured current is 1˜5 amperes, and the measured voltage is 10˜20 volts. Two electrical contacts maintain an arc erosion resisting capability at the condition of a low contact resistance when the electrical contact material is formed on a surface of a metal substrate of an electric connector.
