Aluminium Precision Strip - Precision Metals EU

As the most abundant material on Earth, Aluminium is a popular choice for manufacturers across a number of sectors due to its low cost and many beneficial properties. Aluminium is a corrosion resistant, light weight material, available in both pure and alloyed forms in a wide range of finishes. Among its other key benefits are strength, electrical conductivity, ease of formability and recyclability.

Aluminium Alloys Overview

Aluminium is the third most abundant resource on the planet. It is used widely across many manufacturing sectors due to the ease of machining and forming, requiring low energy input making it highly cost efficient. Consequently it is ideal for extrusion work, milling, drilling, cutting, punching and bending in large or small volumes.

Though commonly found within the Construction industry, the physical properties of Aluminium and its alloys, make it an essential material for Aerospace Automotive and Transport sectors. These Alloys also offer significant environmental advantages with zero toxicity and ease of recycling without changing its integral properties. The low cost in conjunction with material availability, beneficial physical properties and ease of formability makes it an ideal choice for large volume production. This has made it a popular choice for beverage packaging, but also has wider use within Food and beverage production.

Aluminium is a lightweight, soft ductile metal with nonmagnetic and corrosion resistant properties. Furthermore, it has approximately a third of the density of steel, but this does not impact its strength. It is also more durable at lower temperatures and unlike Steels will not become brittle, but actually becomes stronger at low temperatures. However, when heated above 100°C, this can affect strength.

Alloys are available in a range of surface finishes, ranging from dull to reflective, making these alloys ideal for decorative features and metal products.

6082AW-6082A96082Grade 6082 has the highest strength of all the 6000 series alloys, offering excellent corrosion resistance and good machinability and medium high fatigue strength. 6082 is considered a structural alloy, and is commonly used in high stressed applications, such as trusses, cranes and bridges. It has replaced 6061 in many applications. The extruded finish is not as smooth and therefore not as aesthetically pleasing as other alloys in the 6000 series. It can be heat treated or cold formed.Marine, Transport, Energy, Defence, Construction, Food & Beverageroofing and siding materials, heavy duty structures in railroad cars, vehicle bodies, shipbuilding, offshore, bridges, military, bicycles, boilers, flanges, hydraulic systems, mining equipment, pylons and towers, motorboats, nuclear technology, piping, rivets
7000 SERIES (ALLOYED WITH ZINC)
7072AW-7072A97072Grade 7072 is used for high-strength structures, primarily in aircraft, as it offers exceptionally high mechanical strength and is machinable and work hardenable. Whilst it is still a versatile alloy, it has poor corrosion resistance compared to other Aluminium alloys. This grade is also use for cladding other Aluminium alloys. This grade is distinct from other 7000 series alloys, which are alloyed with magnesium for strengthening.Aerospace, Decorative, Marinestorage, heat exchangers, pressure vessels, decorative items, golf heads, tooling, jigs, machinery, high-end aluminium bike frame.
8000 SERIES (ALLOYED WITH OTHER)
8011AW-8011A980118000 series alloys have high formability, with deep drawing formability standing out the most. Additional alloying elements include Iron, nickel, which are used to increase strength without significant loss in electrical conductivity. Like other Aluminium alloys, it offers excellent corrosion resistance.Aerospace, Marine, Food & Beverage, Automotive, Packaging, Decorativeheat exchangers, packaging, vehicles, shipbuilding, insulation materials, decorative items
