Tungsten Alloy High-Temperature Molding Part has a key role in reducing operation cost and production time during hot metal work. The offered molding part includes tungsten heavy metal extrusion die and it is also known as tungsten alloy extrusion die or die casting part. Enriched with tungsten, this molding part  is known for its outstanding resistance properties against wear, thermal cracking and soldering work. Moreover, this tungsten alloy item can endure damaged caused due to heat cycling during hot metal applications. Its non wetting characteristics have crucial part in its extended functional life and it has better working life than its cast iron or steel made counterpart. What is more, it eliminates the necessity of heat treatment process prior to its use. We are reckoned as an established manufacturer of standard grade Tungsten Alloy High-Temperature Molding Part.

Features

  • Tools made of tungsten alloy are completely protected against high temperature and have longer working life than their steel or iron counter parts
  • The extrusion dies made of tungsten have outstanding resistance properties against heat checking or thermal cycling
  • Good soldering resistance capacity
  • Ability to withstand erosion
