Overview
Detailed Material Analysis
Aluminum alloys offer excellent machinability, superior strength-to-weight ratio, and natural corrosion resistance. Ideal for aerospace, automotive, electronics, marine, and general engineering applications.
| Property | Specification |
|---|---|
| Machinability | Excellent – tight tolerances of ±0.025mm to ±0.127mm achievable |
| Weight | ~1/3 the weight of steel (density: 2.70 g/cm³) |
| Corrosion Resistance | Good – natural oxide layer, can be enhanced with anodizing |
| Thermal Conductivity | High (205 W/mK for 6061) – excellent for heat dissipation |
| Min Wall Thickness | 0.75mm (typical) – depends on part geometry |
| Max Part Size | 200 × 80 × 100 cm (varies by machine capacity) |
| Lead Time | 5-10 working days (standard) | Rush: 2-3 days available |
| Typical Price (India) | Starting from ₹300/kg – varies by grade and quantity |
