133/5000 Precious metal composite materials is based on the different using requirements, will have different features of PiCai (brought and baseband) composite molecular diffusion technology, adopts advanced hot rolling into a new type of functional materials, due to the composite effect is very good comprehensive performance, especially for the overall electric properties and wear resistance of precious metals (gold, silver) contact materials are significantly improved, also can save precious metals, reduce product cost.
Surface material: gold, gold alloy, pure silver, silver nickel, silver copper, silver oxide cadmium, silver oxide, etc ；
Base material: pure silver, silver alloy, red copper, brass, phosphor copper, beryllium copper, zinc white copper, nickel, iron, stainless steel, etc.
Surface material: thickness 0.01~1.0mm;
Base material: thickness 010~8.0mm;
Mosaic, double-sided Mosaic, full - back, three - layer composite, lateral compound.
Precious metal composite strip: mainly used in wall switches, protector, thermostat, electric brush and commutator, conductive elements such as micro switch, relay, micro switch, circuit protector, connectors, the tuner and other electronic components production.
