Nickel Based Brazing Powder

Nickel based brazing materials are based on nickel and added with elements that can reduce the melting point and improve the thermal strength, such as chromium, boron, silicon, phosphorus, etc., mainly including NiCrSiB、NiSiB、NiCrSi、NiP、NiCrP, etc. Nickel based brazing materials are widely used inthe brazing of stainless steel, superalloy, iron-based alloy, iron nickel based alloy, diamond, cemented carbide, C / C composites, etc. they have good high temperature resistance, corrosion resistance and excellent mechanical properties.
