FUSiO2N

FUSiO2N

PREFORMED SHAPES FOR THE ALUMINUM
AND OTHER NON-FERROUS INDUSTRIES 

This revolutionary family of high purity fused silica products from Rex Materials is based on a unique technology and manufacturing process which permits the cost-effective production of shapes to meet most design and application requirements. FUSiO2N products and technology permit us to supply customers with a wide range of precision-made shapes small and intricate to extremely large shapes, and shapes with complex internal structures – which do not require costly additional machining.  

FUSiO2N shapes are fused silica (95%+) that are sintered to a high temperature. Today they are used in many non-ferrous applications, including by not limited to: 

  • Thimbles 
  • Control Pins And Spouts 
  • Troughs And Launder Liners 
  • Filter Bowls 
  • Ladles And Pour Basins 
  • Stopper Rods And Nozzles 
  • Dams 
  • Tap Blocks 
  • Back Up Insulation  
  • Cements 

Rex Materials ability to supply quality shapes cost-effectively enables you to use FUSiO2N parts in applications where ordinarily fused silica products have been too expensive.
