Aluminium Alloys

Aluminium alloys and the Ampliform process

Aluminium - LIGHT, STRONG, DURABLE

 

There are various alloys of aluminium available in the world today and it is important to match the alloy you require to the application you want to use it for.

Aluminium is used in such diverse applications as space craft to sewage plant scrapers.

Today's alloy technology allows aluminium to be used in a wide variety of industries.

Extruded aluminium alloys are series 6 alloys and these are the type of alloys required for the Ampliform process. The alloy with the correct properties for the process is type 6063.

For fabricated products that require higher structural properties Aluminium Alloy 6061 or nearest equivalent is used.

The ampliform Process

The ampliform process requires the extrusions to be supplied in the F condition. The material is slotted and stretched before being heat treated to the T6 hardness condition.
