ALLOYS FOR EXTRUDED PROFILES
Etem Gestamp produces all standard and custom aluminium extrusion alloys and tempers in accordance with the European Standard EN 573-3.
Selecting the right alloy, is one of the key ingredients to customers’ success.
In pure form, aluminium is relatively soft. Aluminium can and has to be blended with other metals in forming most of the alloys used today in aluminium extrusion. Each alloy presents a number of different chemical and mechanical characteristics and each alloy tends to serve separately the unique requirements of the final application in terms of strength, surface and post extrusion formability.
The aluminium extrusion process, combined with the right selection of alloy, quenching, post extrusion heat tempering and surface treatment, provide a wide and continuously growing range of market applications and product’s improvements.
