Aluminium Precision Strip - Knight Group

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.

What are the disadvantages of using Aluminium Alloys?

Strength can be affected by temperatures above 100°C

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.
