Nickel Chromium Iron Silicon Alloy Powder

Nickel chromium iron silicon alloy powder is a nickel based self fluxing alloy powder mainly composed of nickel powder, with a certain proportion of chromium powder, iron powder, and silicon powder added.

The so-called self fluxing alloy refers to an alloy material that contains deoxygenated elements such as boron and silicon and has a low melting point. During the heating and melting process, the composition of the alloy can reduce the oxides of itself and the substrate, forming a low melting point borosilicate slag to cover the surface, preventing the oxidation of the alloy and improving its wetting performance, so as to achieve good metallurgical bonding between the alloy and the substrate. The bonding strength between the welding layer of self fluxing alloy and the substrate is generally 30-50kgf/mm2 (300-500Mpa). According to different chemical compositions, welding layers with different hardness of HRC15-65 can be obtained.

Nickel chromium iron silicon alloy powder is the most common nickel based self fluxing alloy powder. It has low melting point, good self melting ability, and comprehensive properties such as wear resistance, corrosion resistance, heat resistance, and oxidation resistance, making it the earliest and most widely used self melting alloy powder.
