Overview
Alloy C63000 is a high-quality extruded material widely used in tough, demanding and corrosive environments. Its exceptional toughness means it is used in applications such as bushings for aircraft landing gear and hydraulic bushings for earth moving equipment.
The nickel content in this material means that it has superior corrosion resistance to marine conditions. Nickel aluminium also has high strength and good wear resistance, making it suitable for bearings, gears and other components with heavy loads and slow speeds. Good lubrication and alignment are essential in bushing applications to ensure optimum performance.
The chemical composition of C63000 is very similar to AB2 Bronze. However, being extruded means it has superior tensile strength, hardness and ductility. A further advantage with this material being extruded is that the diameter quoted is “on size” and has a clean surface finish making it an ideal solution for marine fasteners and fittings such as keel bolts, studs and other parts.
