Brief Introduction of Wallet Nickel Powder

Wallet nickel powder can be used as conductive paste or conductive material such as basic raw material film. It also can greatly improve conductivity and high temperature oxidation, reduction of contact resistance and prevent high-frequency breakdown.
Standing micron particle size :1.3-4,4-8,30-40 micron micron
Chemical composition: 0.3-15% silver content, silver coating layer can also be customized for a particular coating composition.

Nickel is one of the four elements that are ferromagnetic around room temperature. Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is chiefly valuable in the modern world for the alloys it forms; about 60% of world production is used in nickel-steels (particularly stainless steel). Other common alloys, as well as some new superalloys, make up most of the remainder of world nickel use, with chemical uses for nickel compounds consuming less than 3% of production. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation. Enzymes of some microorganisms and plants contain nickel as an active center, which makes the metal an essential nutrient for them.
