  A new electrical contact alloy with high reliability based on gold

  摘要：

  A new gold alloy (NSCGA) was designed and prepared for light duty precision contacts. The microstructure, mechanical, electrical and applied properties of the NSCGA alloy were studied. The NSCGA alloy contains copper, palladium, platinum, nickel and rhodium as well as gold. The unique structure comprised of two phases, a gold-rich solid solution as the matrix and a platinum-rich solid solution as a strengthening phase. The matrix presents short-range ordering in the temperature range 200-900degreesC, which leads to the specific resistance of the alloy decreasing, and a modulated structure at low temperatures, which is responsible for age strengthening. The NSCGA alloy has low specific resistance, high tensile strength and high Vickers hardness. Various TO-5 type relays (TO-5 relay is a sealed mini relay with magnetic preservation) with NSCGA alloy as contacts were prepared and tested in a special relay factory under industrial conditions. NSCGA alloy contacts showed stable and low contact resistance, long loading life and high reliability, superior to that of an available conventional six-component palladium alloy. The NSCGA alloy and the composites with NSCGA alloy as a covering layer and copper alloys as a base have been evaluated in various TO-5 type mini relays and other electric products.
