AlMg3 (EN AW 5754) – The versatile aluminum alloy for high corrosion resistance
The aluminum alloy AlMg3, known as EN AW 5754 according to DIN, is one of the most popular alloys for industrial use. Its excellent corrosion resistance, good weldability, and medium strength make it an optimal choice for many applications in vehicle construction, apparatus engineering, as well as in shipbuilding and construction.
What is AlMg3 (EN AW 5754)?
The alloy EN AW 5754 belongs to the group of aluminum-magnesium alloys. The high magnesium content (approx. 3%) ensures excellent resistance to corrosion, even in saline environments. This makes it ideal for outdoor applications and the marine sector.
The typical designation is:
-
AlMg3 = EN AW 5754 (material no. 3.3535)
Properties of EN AW 5754 at a glance
- Very good corrosion resistance – Also in marine atmosphere
- Good weldability – Suitable for MIG, TIG, and resistance welding
- Good anodizability – For decorative or protective surface treatment
Mechanical values of AlMg3 (EN AW 5754)
| Property | Value (thickness from approx. 6 mm) |
|---|---|
| Tensile strength | 190 – 250 N/qmm |
| Yield strength | 80 – 140 N/qmm |
| Hardness | approx. 50 – 80 Brinell |
| Thermal conductivity | approx. 1.5 W/cm °C |
| Corrosion behavior | Very good – also against seawater |
Typical Applications of EN AW 5754
Thanks to its combination of lightness, corrosion protection, and formability, the EN AW 5754 (AlMg3) alloy is in demand in many areas:
- Automotive industry – body parts, floors, walls and interior components
- Shipbuilding – decks, plates, covers and structural parts
- Construction – facades, roofs, window frames
- Food industry – containers, apparatus, plant components
- Mechanical engineering – housings, covers, plates, brackets
- Sheet metal processing – for deep drawing, bending, punching
Why choose AlMg3 over other aluminum alloys?
Compared to other alloys such as EN AW 1050 (pure aluminum) or EN AW 6082 (high-strength AlMgSi alloy), 5754 offers an ideal combination of formability, corrosion resistance, and moderate strength.
| Property | EN AW 1050 | EN AW 5754 (AlMg3) | EN AW 6082 |
