What’s the difference between Aluminum and Steel?
Aluminum vs Steel
| Feature | Aluminum | Steel |
|---|---|---|
| Weight | Lightweight (~1/3 of steel) | Heavy, high density |
| Strength | Moderate (high strength-to-weight) | Very high strength |
| Corrosion Resistance | Excellent (natural oxide layer) | Requires coating or treatment |
| Machinability | Excellent | Good |
| Weldability | Good (requires technique) | Excellent |
| Cost | Higher per lb | More economical |
| Best For | Lightweight, corrosion-resistant applications | Structural, heavy-duty applications |
Not sure which to choose?
Use Aluminum when weight and corrosion resistance matter.
Use Steel when strength and cost efficiency are the priority.
