1060 aluminium — composition, properties and extrusion notes
99.6% pure aluminium for conductivity, ductility and chemical resistance.
How it compares
Relative to the other grades we extrude. This is a selection aid, not a specification.
Mechanical properties
| Temper | Tensile (MPa) | Yield (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| O | 70 | 30 | 25 | 20 |
| H14 | 110 | 95 | 12 | 32 |
Typical values for extruded product. Minimum guaranteed values depend on temper and product form — the mill certificate governs.
Composition limits
| Element | Limit (%) |
|---|---|
| Si | 0.25 |
| Fe | 0.35 |
| Cu | 0.05 |
| Mn | 0.03 |
| Mg | 0.03 |
| Zn | 0.05 |
| Ti | 0.03 |

Single figures are maxima; ranges are the permitted window.
Working with this alloy
- Density
- 2.7 g/cm³
- Common tempers
- O, H14, H24
Physical properties
| Property | Value |
|---|---|
| Thermal conductivity | 234 W/m·K |
| Melting range | 646–657 °C |
| Electrical conductivity | 62 % IACS |
When to use it
Chosen where conductivity or ductility matters more than strength. Very soft, so it is usually formed rather than machined.
Typical applications
- Electrical busbars and conductors
- Chemical process equipment
- Heat exchangers and reflectors
- Signage and nameplates
Other alloys
1100
99.0% pure aluminium — the workhorse of the commercially pure grades.
3003
Manganese-bearing alloy — about 20% stronger than 1100 with similar workability.
5052
The strongest common non-heat-treatable sheet alloy, and the marine standard.
6005A
A stronger structural alternative to 6063, developed for extruded transport profiles.
6060
A close relative of 6063, tuned for a slightly brighter anodised finish.
