Aluminium Extrusion


How does the cost of dies and tooling for aluminium extrusions compare with the costs of other processes and materials?

The cost of dies for aluminium extrusion is normally much lower than the cost of tooling for other processes, like die casting, forming, impact extrusion, stamping or vinyl extrusion.

How does the strength-to-weight ratio for aluminium extrusions compare with the ratio for other materials?

The strength-to-weight ratio of aluminium extrusions is quite good when compared with the ratios for other materials, such as rolled form steel, copper extrusions, molded plastic or wood.

What sort of tolerances can be achieved with aluminium extrusions?

Aluminium extrusions generally provide much tighter tolerances than other materials, including vinyl extrusions. Altec consistently produces very precise tolerances, in accordance with each customer’s specifications and as testified by our ISO certification. For more information on this topic in general.

What are the advantages of using the 6xxx series of alloys in aluminium extrusions?

The 6xxx series, which incorporates magnesium and silicon, provide good extrudability, strength, corrosion resistance, formability and machinability.

If you can produce custom aluminium extrusion profiles by the customs drawings?

There are nearly 50% of the extruded aluminium products are made by the customs drawing or samples not only window profiles but also nearly 40% industrial profiles… If possible, please send us your enquiry together with the drawings.


A major asset in a age of environmental concern, Modern techniques have perfected ways of returning used aluminium to a new metal without the loss of purity or mechanical characteristics. The energy cost represents just 5% of the extraction energy required to produce from scratch.

Nevilles Precision Engineering offer industry leading aluminium extrusion services.
