Alternative designations: 3.1645; EN 573-3; AlCu4PbMgMn.
This aluminium alloy has copper as its main alloying element (4-5%) of copper. It is a short chipped alloy that is durable, light, highly functional, and has the same high mechanical properties as AW 2030. It is also suitable for threading, heat treatment, and high-speed machining. All these properties make EN AW 2007 widely used in the production of machine parts, bolts, rivets nuts, screws, and threaded bars. However, this aluminium grade has low weld ability and low corrosion resistance; therefore it is recommended to carry out protective anodizing after part machining.

Alternative designations: 3.3547; Alloy 5083; EN 573-3; UNS A95083; ASTM B209; AlMg4.5Mn0.7
AW 5083 is renowned for its excellent performance in severe environments. It contains magnesium and small traces of chromium and manganese. This grade has very high resistance to corrosion in both chemical and marine environments. Of all the non-heat treatable alloys, AW 5080 has the highest strength; a property which it retains even after welding. While this alloy should not be used in applications with temperatures higher than 65°C, it excels in low temperature applications.
Due to its set of desirable properties, AW 5080 is used in numerous applications including cryogenic equipment, marine applications, pressure equipment, chemical applications, welded constructions, and vehicle bodies.

Alternative designations: 3.3535; Alloy 5754; EN 573-3; U21NS A95754; ASTM B 209; Al-Mg3.
Being a wrought aluminium-magnesium alloy with the highest % of aluminium, AW 5754 can be rolled, forged, and extruded. It is also non heat-treatable and can be cold-worked to increase its strength, but at a lower ductility. In addition, this alloy has excellent resistance to corrosion and has high strength. Considering these properties, it is understandable that AW 5754 is one of the most popular CNC machined aluminium grades. It is typically used in welded structures, flooring applications, fishing equipment, vehicle bodies, food processing, and rivets.

Alternative designations: 3.3206; ISO 6361; UNS A96060; ASTM B 221; AlMgSi0,5 This is a magnesium and silicon-containing wrought aluminium alloy. It is heat-treatable and has average strength, good weld ability, and good form ability. It is also highly resistant to corrosion; a property which can be improved even further through anodizing. EN AW 6060 is often used in construction, food processing, medical equipment, and automotive engineering.

Alternative designations: 3.4365; UNS A96082; H30; Al-Zn6MgCu.
Zinc is the primary alloying element in this grade of aluminium. Although EN AW 7075 has average machine ability, poor cold forming properties, and is not suitable for both welding and soldering; it has a high strength to density ratio, excellent resistance to atmospheric and marine environments, and strength comparable to some steel alloys. This alloy is employed in a very wide range of applications including hang glider and bicycle frames, rock climbing equipment, weaponry, and mold tool manufacturing.

Alternative designations: 3.3211, UNS A96061, A6061, Al-Mg1SiCu.
This alloy contains magnesium and silicon as its major alloying elements with trace amounts of copper. With a tensile strength of 180Mpa, this is a high strength alloy and is very suitable for highly loaded structures such as scaffolds, rail coaches, machine and aerospace parts.

Alternative designations: 3.2315, UNS A96082, A-SGM0,7, Al-Si1Mg.
Typically formed by rolling and extrusion, this alloy has medium strength with very good weld ability and thermal conductivity. It has high stress corrosion cracking resistance. It has a tensile strength that ranges from 140 – 330MPa. It is heavily employed in offshore construction and containers.
