Nissan Armada 2025-2026 Service and Repair Manual: Comparision of Chemical and Physical Properties between Aluminum and Iron
| Property | Aluminum alloy | Iron | Effect of welding |
|---|---|---|---|
| Melting temperature °C (°F) | 560 - 640 (1,040 - 1,184) | 600 × 2.5 (1,112 × 2.5) |
|
Heat conduction efficiency cal/cm/sec/°C (BTU in/m2/h/°F) | 0.28 (812.69) | 0.28 × 0.57 (812.69 × 0.57) | Large amount of heat in a short time required for welding. |
| Modulus of elasticity kg/mm2 (lb/in2) | 7,000 (9,646,875) | 7,000 × 3 (9,646,875 × 3) | Easily deformed and very fragile. |
Coefficient of linear expansion (10-6) | 23.8 | 23.8 × 0.5 | |
| Conductivity (%) | 30 | 30 × 0.52 | Large current flow is required when compared to iron. |
| Oxidized film | Al2 O3 | Fe2 O3 | The melting point of aluminum alloy oxidized film is 2,020°C (3,668°F). In order to remove this film, cleaning by argon welding or flux treatment is required. |
Welding (aluminum)
To repair a crack or a hole in a steel plate, welding is usually used. Either oxygen and acetylene gas welding, arc welding, or brazing is commonly used. For aluminum alloy panels, TIG or MIG welding, ...
Filler Metal
For a filler metal, TIG welding rods and MIG welding electrode wires are available. Use filler metal that is suitable to the parent metal.
