Copper-aluminium alloys
ALUMINIUM-BRONZES
The nickel aluminium bronze alloys are fairly complex materials and, during manufacture, require good control of the metal structure by attention to composition and heat treatment.
Features of Aluminium-Bronze
Nickel aluminium bronzes are available in both cast and wrought product forms and have a unique combination of properties:
- Excellent wear and galling resistance
- High strength
- Density (10% lighter than steel)
- Non-sparking
- Low magnetic permeability (of <1.03 μ in selected grades)
- High corrosion resistance
- Good stress corrosion properties
- Good cryogenic properties
- High resistance to cavitation
- Damping capacity twice that of steel
- High resistance to biofouling
- A protective oxide surface film which has the ability to self-repair.
Weldability of Aluminium-Bronze
The low electrical and thermal conductivity of aluminium-bronze alloys enhances their weldability. However, is it crucial to remove all of the aluminium oxide layer on the surface of the material before welding.
Preheat and interpass temperature depends on thickness of the part to be repaired. Normally the preheating temperature will be from 100 °C to 250 °C (212 °F to 480 °F). Where thickness of part is less than 20mm, preheating will normally not be required. Stress relieving temperature for welds made in Aluminium Bronze C61400: 340 °C (650 °F).
