Aluminium alloy EN-AW 8079
Pure aluminium, mat. no. 3.0502 (Al 99.0%)
- Applications:
Due to its low specific weight and good formability, aluminium can be used for a wide range of applications. EN-AW8079 contains iron and silicon, giving it a higher tensile strength. This allow is therefore used for aluminium foils of a thickness of
up to around 0.05 mm.
Due to its relatively good thermal conductivity, pure aluminium is also used for heat exchangers (however, alloys 3003 or 6063 should be used in soldered heat exchangers).
As a result of its high electrical conductivity, aluminium can also be used in the electronics industry and, thanks to its high reflective properties, in lamp reflectors
Aluminium is not suitable for springs.

Aluminium should not be used for springs.
Temperatures of more than 300 ° Celsius should be avoided.
8. Physical properties

Thermal conductivity: 210-230 W/(m °C) depending on the temperature Spec. heatcapacity: 897 J/(kg °C) mean value at 50 – 100 °C Thermal expansion: 23,6 x 10 -6 (between 30 - 100 °C)
Electric conductivity: 36.6 x 10 -6 A/(V x m) (equivalent to 59 % IACS)
Modus of elasticity: 69 000 MPa at 20 °C
Relative permeability µr: aluminium is not magnetisable
9. Blanking
We recommend a punch-to-die clearance of 4-10 % of the strip thickness.
The corner radius should be at least 0.25 mm and the punching die should be at least twice the strip thickness.
10. Laser cutting
This alloy can be laser cut by solid state lasers.
11. Photo etching
Aluminium can be etched easily.
12. Bending
Soft aluminium can be bent or drawn easily.
Please notice the following minimum bending radius for aluminium in the temper rolled condition (please see DIN EN 486-2, table 4):
Up to a thickness of 0.20mm:
- x strip thickness at bending at right angle (90°) to the rolling direction.
- x strip thickness at bending parallel to the rolling direction (this data is missing in the DIN EN485-2).
13. Flat grinding and polishing
Aluminium is not magnetic and can not be hold by magnetic clamping devices of flat grinding machines. Aluminium is difficult to polish.
14. Welding
Aluminium is suitable for welding with MIG or WIG.
15. Corrosion resistance
Aluminium has a passivating oxide layer and is resistant to many environmental conditions. A strong caustic or acidic environment solves the passivating layer and corrodes the material.
Aluminium is resistant against sea water.
At a contact to unalloyed steel can cause rust marks. We also suggest a galvanic isolation to copper and copper alloys.
