Sialon Wire Extrusion Dies

The extrusion and drawing of copper, brass and nimonic alloys requires the use of a die, traditionally manufactured in steel. In recent times however, extrusion dies made from Syalon 101 have been successfully used to overcome many of the problems traditionally associated with metal dies, such as poor surface finish and short die life.

Advantages of Syalon 101 Extrusion Dies

Syalon 101 possesses a number of properties which make it an excellent candidate for extrusion dies. These include high hot hardness, strength and toughness, excellent thermal properties particularly thermal shock resistance, chemical stability and good frictional properties.

Syalon 101 Extrusion Dies with Non-Ferrous and Nimonic Alloys

Syalon 101 dies and plugs perform extremely well in the extrusion of copper, brass and nimonic alloys, with unsurpassed resistance to wear and thermal shock creating extended die lives. Also, since Syalon materials do not contain a metallic phase, die pick-up can be eliminated, which results in improved continuity of the extrusion process, enhanced surface finish of the product, reduced scrap rates and increased productivity.

When extruding nimonic alloys, Syalon 101 dies last up to 120 times longer than steel dies. For extruding brass, Syalon 101 dies extruded 250 tons of brass compared to 100 tons through conventional dies. For copper, Syalon extruded 75 tons compared to 40 tons for a conventional die.
