серебряный сплав вольфрама

Our Silver tungsten alloycontaining between 20 and 45% silver are used for electrical contacts. These materials are produced via powder metallurgical techniques(Press-sinter-infiltration or Press-sinter-repress)due to their widely different melting points. we also produce the silver tungsten carbide materials to answer the higher arc resistance to mechanical wear need.Typical properties:Ag(wt%)W(wt/%)Density(g/cm³)Electrical conductivity(%IACS)Hardness RockwellAgW5545±2.0Balance13.555465 BAgW6040±2.0Balance14.005171 BAgW6535±2.0Balance14.504875 BAgW7030±2.0Balance14.904582 BAgW7525±2.0Balance15.404186 BAgW8020±2.0Balance16.103789 B
