Products Description
Ni95Al5 thermal spray wire is a commonly used spray material with many excellent properties and is suitable for various high-temperature and corrosion-resistant coating applications. It is mainly composed of nickel (Ni) and aluminum (Al), of which the nickel content accounts for about 95% and the aluminum content accounts for about 5%. This chemical composition makes Ni95Al5 alloy have good high temperature resistance and oxidation resistance, forming a dense oxide layer in high temperature environment, effectively protecting the base material from oxidative corrosion.
The diameter of Ni95Al5 thermal spray wire is usually between 0.8mm and 3.2mm, and the tensile strength can reach 350MPa to 550MPa, which ensures that the spray coating has good mechanical properties and strength. Its melting point is approximately 1260°C (2300°F), giving it excellent stability under high temperature conditions.
In addition, Ni95Al5 alloy also has good thermal conductivity and certain corrosion resistance, although its corrosion resistance is slightly inferior to other alloys such as Inconel 625 relative to corrosive media in some specific environments. However, the coating hardness of Ni95Al5 alloy is usually between 200HV and 300HV, which has better wear resistance and scratch resistance.
