ERGAL 6061

Ergal 6061 is a medium-high-strength aluminium alloy with excellent machinability, corrosion resistance and good weldability.

Chemical composition

AlMg1SiCu

ISO Standard

3.3211

It is less resistant than the 7075but offers a better compromise between mechanical strength, lightness and workabilitymaking it ideal for precision mechanical small parts with diameters between 3 and 32 mm e lengths up to 250 mm.

Why use Ergal 6061?

1
Good mechanical resistance
- Tensile strength between 310-330 MPa (inferior to 7075, but superior to other aluminas)
- Excellent for structural components and parts subject to moderate load
2
Lightness
- Lower weight than steels (approx. 1/3 of the weight), but with good robustness
3
Excellent corrosion resistance
- Much higher than the 7075thanks to the presence of magnesium and silicon
- Ideal for applications in wet and marine environments
4
Excellent workability
- Easy to machine with lathes and milling cutters
- Good surface finish for precision small parts
5
Good weldability
- Unlike the 7075, 6061 welds easily
- Perfect for components requiring assembly by welding
6
Resistance to wear and fatigue
- Excellent durability for parts subject to repeated stress
7
Possibility of anodising
- Can be anodised to improve corrosion resistance and aesthetics
