Copper clad Aluminium the engineered alternative to Copper

Hydrostatic Extrusion

Materials extruded by our hydrostatic extrusion process have performance parameters that are not achievable by any other extrusion method, opening up a performance-enhancing/cost-saving route for equipment and product designers.  In addition to Cuponal, we extrude superconducting materials, aluminium-based high performance alloys and a wide range of specialist metal composites. The functional principle of hydrostatic extrusion, using oil at high pressure around the billet to effect the extrusion, eliminates friction between the billet and the press container. Thus, extremely high reduction ratios – up to 300:1 in one pass – are achievable.  The uniform flow of material in this process produces a uniform edge-to-edge fine grain, homogeneous structure in the extruded product.
