Extrusion - our speciality

The four presses of Sapa France, allow the extrusion of a large variety of aluminium profiles according to customer request and specifications.

Hollow dies

The billet, preheated to a temperature of 450-550°C, is introduced into a container sealed in one of its end by a die, which will give the metal its final form. At the other end, a hydraulic actuating cylinder pushes the billet, obliging the hot metal to pass through the die.

Cooling and stretching

The extruded sections are then cooled and stretched. It is therafter, in a ageing furnace, that the sections acquire their particular mechanical properties and conformity with the customer specifications.

As well as offering a large number of standard profiles we can help our customers design the perfect extrusion for their particular application. 

Standard alloys include:
6060, 6106, 6005A and 6351 (others available on request) with additional 6101 and 6082 of Albi.
