PROPERTIES OF ALUMINIUM
Excerpt on some essential materials
AlMgSi0,5 / EN AW 6060 – 130 – 245 N/mm2
is the most commonly used material and belongs to the easily pressable alloys.
This alloy stands out due to
- particulary good anodising quality,
- seawater and thus corrosion resistance,
- good weldability,
- very good bending capacity - with corresponding strength
DIN 17615 - AlMgSi0,5 precision sections - is relevant for this material. It takes into account the quite good formability and the narrow tolerances and thin wall thicknesses possible as a result compared to other materials.
Applications: Architecture, mechanical engineering, furniture, vehicle construction, electrical engineering
AlMgSi0,7 / EN AW 6005A – 270 N/mm2
Similar properties to AlMgSi 0,5, but higher strengths - up to 270 N/mm2 - for appropriate applications.
Applications: Mechanically stressed components
AlMgSi1 / EN AW 6082 – 205 bis 310 N/mm2
- with high strength values
- good weldability
- seawater and therefore corrosion resistant
- technically anodisable - not used for decorative purposes
Applications: Components subject to high mechanical stress
AlCuMgPb / EN AW 2007 – 340 bis 370 N/mm2
Naturally hard material - especially suitable for machining (short chip due to Pb content).
Applications: Drilling and turning material
AlZn4,5Mg1 / EN AW 7020 – bis 350 N/mm2
Difficult to press construction material with excellent weldability.
Applications: highly stressed welded structures, especially in construction and mechanical engineering.
AlZnMgCu1,5 / EN AW 7075 – 500 bis 530 N/mm2
The material for highest loads and stresses (very low corrosion resistance)
Applications: Structures with very high stress in aircraft, vehicle and mechanical engineering.
Al99,5 / EN AW 1050 – H0 bis H28
Naturally hard material, mainly for rolled products
Applications: Metal processing
AlMg1 / EN AW 5005 – H0 bis H38
Naturally hard material, resistant to seawater, good weldability, good anodising properties, for decorative surfaces.
Applications: Facade, metal and vehicle construction, packaging
AlMg3 / EN AW 5754 – bis 180 N/mm2
Naturally hard material for rolled products and simple profile cross-sections
- with very good corrosion resistance,
- good weldability,
- good anodising quality.
Applications: Architecture, mechanical engineering and furniture industry
AlMg4,5Mn / EN AW 5083 – H0 bis H362
Naturally hard material, resistant to seawater, good weldability, excellently suitable for statically stressed constructions.
Applications: Important alloy for shipbuilding, furthermore in mechanical engineering, vehicle and apparatus construction, civil engineering
