Alloys
Aluminum Grades from 1060 to 7075
The grade decides strength, conductivity, surface, formability and cost. Compare every grade we cast and supply, from pure 1060 to high-strength 7075.
CharMax supplies aluminum from pure 1060 and 1100, through formable 3003 and marine-grade 5052, the 6000-series extrusion alloys 6060, 6063, 6061, 6005A and 6082, to high-strength 7005 and 7075. Pure grades maximise conductivity; 5052 resists corrosion; 6063 gives the best extruded surface; 6061 is the all-round structural grade; 7075 is the strongest.
All alloys
1060 Aluminum
99.6 % pure aluminum: maximum conductivity and formability.
Explore
1100 Aluminum
Commercially pure aluminum with a little more strength than 1060.
Explore 3003 Aluminum
General-purpose manganese alloy: stronger than pure aluminum, still very formable.
Explore 5052 Aluminum
Marine-grade corrosion resistance and good strength for sheet-metal parts.
Explore 6061 Aluminum
The structural all-rounder: strong, machinable and weldable.
Explore
6063 Aluminum
The architectural alloy: best surface, best anodizing, easiest to extrude.
Explore
6005A Aluminum
Structural strength with the extrudability thin-walled hollows need.
Explore
6082 Aluminum
Highest strength of the common 6xxx alloys — Europe's structural standard.
Explore
7005 Aluminum
High-strength 7000-series alloy that can be welded — bicycles and skates.
Explore
7075 Aluminum
One of the strongest aluminum alloys: molds, tooling and high-stress parts.

| 6082 | T6 | ≈ 290–340 MPa | ≈ 250–310 MPa | ≈ 170–180 W/m·K | Fair | Fair–good | Very good |
| 7005 | Aged | ≈ 350–390 MPa | ≈ 290–345 MPa | ≈ 150 W/m·K | Fair | Good | Good |
| 7075 | T6 | ≈ 570 MPa | ≈ 500 MPa | ≈ 130 W/m·K | Poor | Good (technical) | Excellent |
Indicative ranges spanning typical EN 755-2 minimums and published typical values. Guaranteed minimums depend on temper, wall thickness and profile type — the mill certificate for each lot is the controlling document.
FAQ
Frequently asked questions
Which aluminum grades does CharMax supply?
1060, 1100, 3003, 5052, 6060, 6061, 6063, 6005A, 6082, 7005 and 7075 — as extruded profiles, tubes, bars and rods, and plate and sheet — all cast in-house from primary aluminum.
What is the most common aluminum alloy for extrusion?
6063. It extrudes easily into complex shapes, gives the best surface and anodizing quality, and offers enough strength for most architectural, thermal and framing applications.
Which aluminum alloy is strongest for extrusion?
Among the common 6000-series extrusion alloys, 6082-T6 and 6061-T6 are the strongest (roughly 260–340 MPa tensile). 7000-series alloys are stronger still but are harder to extrude and are used for specialist applications.
How do I choose between 6063 and 6061?
Start with 6063 for appearance, complex shapes and thermal parts; move to 6061 (or 6082/6005A) when load, machining or fatigue demands it. Our 6061 vs 6063 guide walks through the decision.
