5456 Aluminum Alloy Properties
- 5456 aluminum alloy can be formed by rolling, extruding and forging, but it cannot be cast.
- 5456 aluminum can be cold worked to produce a stronger but less ductile state. It is susceptible to exfoliation corrosion when held at temperatures above 65 °C (150 °F) for extended periods of time.
- 5456 aluminum is often anodized and painted or coated with an aluminum layer on the surface to improve corrosion resistance.
- Machinability: Aluminum 5456 alloy has poor machinability and requires the use of oil lubricants and carbide cutting tools.
- Forming: Aluminum 5456 alloy has poor formability and is not suitable for extensive cold working.
- Welding: Arc welding is the preferred method, gas welding can also be used, but the effect is not as good as arc welding.
- Hot working: Can be hot worked at 218°C (425°F), helping to avoid the effects of high stress on cold worked shapes.
- Cold working: It has good cold working ability, but excessive cold working should be avoided to avoid stress corrosion cracking.
- Annealing: Annealing may be performed at 343°C (650°F) and should be followed by air cooling.
