Processing of Non-ferrous Alloys through Extrustion

Abstract

Extrusion processing is emerging as one of the impor-tant mechanical processing techniques since the last couple of decades both in terms of tonnage production and the variety of profiles. Particularly this is so in the field of aluminium alloys which are used as structurals, architectural and other engineering materials including electrical conductors. This is clear from the fact that the production of aluminium extrusions shot up from 22,000 tpy in 1980 to 62,000 tpy in 1990 and increasing at the rate of 10-15% every year. Similarly magnesium-aluminium extrusions in simple and integrated sections are being extensively used in defence and space applications because of their light weight and high strength.
