Materials & Alloys
Compare the grades
Tensile and yield values are for the strongest common temper of each grade, so the comparison is like for like. Physical properties and the full temper range are on each alloy page.
| Grade | Series | Family | Density (g/cm³) | Tensile (MPa) | Yield (MPa) | Extrudability |
|---|---|---|---|---|---|---|
| 1060 | 1xxx | Commercially pure | 2.7 | 110 | 95 | Good |
| 1100 | 1xxx | Commercially pure | 2.71 | 130 | 120 | Good |
| 3003 | 3xxx | Manganese alloy | 2.73 | 150 | 145 | Fair |
| 5052 | 5xxx | Magnesium alloy | 2.68 | 230 | 195 | Fair |
| 6005A | 6xxx | Magnesium-silicon alloy | 2.7 | 270 | 225 | Very good |
| 6060 | 6xxx | Magnesium-silicon alloy | 2.7 | 190 | 150 | Excellent |
| 6061 | 6xxx | Magnesium-silicon alloy | 2.7 | 310 | 275 | Good |
| 6063 | 6xxx | Magnesium-silicon alloy | 2.7 | 185 | 170 | Excellent |
| 6082 | 6xxx | Magnesium-silicon alloy | 2.71 | 310 | 260 | Good |

Alloy pages
1060
99.6% pure aluminium for conductivity, ductility and chemical resistance.
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.
6061
The general-purpose structural alloy: strong, weldable, machinable and corrosion resistant.
6063
The architectural extrusion alloy — the best surface finish and the easiest to extrude.
6082
The strongest of the 6xxx extrusion alloys, with good machining behaviour.
7005
A weldable high-strength alloy — the classic bicycle frame material.
7075
The highest-strength aluminium in common use — aerospace grade.
