630 Nickel Aluminium Bronze

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.

954 Aluminium Bronze

Alloy 954 is a high strength aluminium bronze that is widely used in heavy duty applications such as forestry, mining, construction & marine. It is a very hard material which has excellent strength and wear resistance, yet still retains good machining properties. Alloy 954 also has good resistance to impact loading, but it should be noted that proper lubrication is necessary to prevent metal to metal contact. Inadequate lubrication is likely to cause scoring or ‘galling’, and consequent damage to the bronze component and/or other moving parts. General corrosion resistance is good but de-luminification may occur under some circumstances. All Kormax 954 Aluminium Bronze is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength is superior to sand-casting methods. This also means that the material has a fine grain structure and is free from porosity.

AB2 Nickel Aluminium Bronze

Alloy AB2 is a nickel aluminium bronze that is widely used in marine applications. The nickel content in this material means that it has superior corrosion resistance to marine conditions. AB2 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 required to ensure optimum performance.
