Silver alloy wire-tape-contact
The silver alloy wire-strip-contacts used in electrical contacts mainly include: pure silver, fine-grained silver, silver nickel, silver copper, silver tin oxide, silver tin oxide indium oxide, silver zinc oxide, silver cadmium oxide and other products.
Craft:
1. It is produced by sintering extrusion process, and its density can be as high as 99.9%. At the same time, the second component in the silver base becomes fibrous, and the fiber arrangement direction is perpendicular to the surface of the electrical contact product, which improves the welding resistance and resistance of the material. Arc burnout and mechanical wear resistance.
2. Trace elements are added to wires such as silver tin oxide, silver tin oxide indium oxide, silver copper, silver nickel, silver zinc oxide, etc. to achieve the effect of dispersion strengthening, improve the mechanical strength of the material product, improve the physical and mechanical properties of the material and the resistance to arc burning. The isoelectric performance is greatly improved;
3. The chemical coating method, co-precipitation method, mechanical alloying and pre-oxidation process are used to refine the grains of the material, the structure is uniform, the microstructure does not appear segregated, the oxide-poor ridge area is eliminated, and the material with excellent performance is produced. Material.
Specification Type:
Wire: wire diameter 0.2~6.0mm;
Strip: thickness 0.05~3.5mm, width 1.5~80mm;
application:
Silver alloy wire-belt-contact contactors, relays, starters, voltage controllers, AC and DC power relays, DC contactors for medium and low voltage electrical appliances such as automotive electrical appliances, and DC contactors for power protection switches, leakage protection switches, AC relays, DZ15L Series leakage circuit breakers, etc., some large-capacity switches also use silver zinc oxide materials, such as ME-type circuit breakers.
