Aluminium Alloys


1050 is unalloyed non-heat treatable aluminium that is easily worked and has high resistance to corrosion.


C250 is manufactured from a 5083 type alloy and machined to industry standard thickness and flatness tolerances, poly-coated both sides. Special casting and heat treatment techniques make it extremely stress free, whilst retaining 85-90% of the strength of rolled plate. It retains flatness and dimensional tolerances after machining and even after repeated heating and cooling. C250 has excellent machining, welding and anodising properties.


2014A has high mechanical properties with good machinability.  Finished components often need a protective coating to avoid corrosion.


2024 is a high strength heat treatable alloy with excellent fatigue resistance. Its workability is good and it can easily be machined to a high finish. Its weldability is generally poor although it can be flash spot or seam welded.


2618 is a strong aluminium alloy containing nominally 2% copper and 1.5% magnesium.


4032 is commonly used for manufacturing pistons with fairly good machinability. The alloy is weldable although gas welding should be avoided.


5083 is a popular high strength aluminium alloy which is well suited to welding applications that require excellent corrosion resistance.


5251 is a medium strength alloy with high corrosion resistance. This alloy is weldable and finds many applications in marine environments.


6063 is a medium strength alloy commonly used for bespoke aluminium sections in architectural and transport applications.


6082 is a popular heat treatable alloy with medium strength which is combined with good anodising, welding, corrosion resistance and machinability.


7068 is the alloy with the highest mechanical strength of all aluminium alloys and matching that of certain steels.


7020 is a heat treatable alloy that age hardens naturally and therefore will recover properties in a heat affected zone after welding. 7020 is used in armoured vehicles, motorcycle and bicycle frames.


7050 has a combination of strength, toughness and stress corrosion cracking resistance. This 7050 alloy has much better toughness and corrosion resistance characteristics than ally 7075. It retains its strength properties in thicker sections whilst maintaining its other qualities because it is less quench sensitive than most aerospace aluminium alloys.


7075 is a high strength and hardness alloy primarily used in aerospace applications, with good machinability but limited corrosion resistance.


L93 is a high strength heat treatable alloy with good machinability. Cold formability can be limited when used fully

heat treated as can weldability. Natural corrosion resistance is poor therefore a protective coating is often required.


L95 is a high strength heat treatable aluminium alloy with excellent hardness properties. In the annealed condition this alloy can be flash spot welded and is easily formed. L93 is often used in aerospace applications for highly stressed parts.


L111 is a popular medium strength alloy with good corrosion resistance and good workability. In the annealed condition it can be easily welded and formed. L111 has good anodising properties and is designed as a general purpose alloy, suitable for many applications.

L163 / L164

A high strength 2014A alloy clad with 1050A to improve corrosion resistance. It has high mechanical properties with good machinability. L163:T3, L164:T4/T6.


L168 is a high strength alloy containing 3.9% to 5% copper. L168 has high mechanical properties with good machinability. Finished components often need a protective coating to avoid corrosion and cold formability can be limited when used fully heat treated, as can weldability.
