What Are Gallium-Based Alloys

Nov 05, 2021

Gallium-based alloys are based on gallium, adding other metals, such as tungsten, cobalt, titanium, iron and other metals, to make gallium-based alloys.

Ni65WC is a nickel-based alloy, and there is also a nickel-based stainless steel, such as 304, 316 and other stainless steels. Nickel-based alloys added with tungsten, molybdenum, cobalt, titanium, etc. usually have high hardness, good wear resistance, and good high temperature resistance. They are usually used for special purposes, such as mining alloys, wear-resistant alloys, coatings, tool alloys, and strong magnetism.

In addition to bearing abrasive wear, adhesive wear and other types of wear, a class of nickel alloys that also withstand medium corrosion and high temperature oxidation. Therefore, the working conditions of nickel-based are much more complicated than those of general wear-resistant steel and wear-resistant cast iron. The chemical composition of wear-resistant gallium-based alloy is (%): C 0.10~0.20, Mn 0.25, Si 0.60, Cr 14.00~17.00, Mo 4.50~6.00, Al 2.5~3.50, Fe 8.00~12.00, Ti 1.50~2.50, Ni margin. The tensile strength at 820°C was 520 MPa and the elongation was 3%. This material is generally used as wear-resistant parts that work in air or low-lubricating liquids, such as valves, pump parts, pistons, piston rings, seals, brakes, thrusters in petrochemical equipment, atomic energy equipment, and jet aircraft and internal combustion engines. Rods, vanes and blades, etc.
