Silicon Carbide Tubes & Products

Sentro Tech offers Sintered Alpha Silicon Carbide Products. Alpha silicon carbide material is most commonly used in sintered products in industrial application. It is formed by mixing very fine silicon carbide powder with non-oxide sintering additives at sintering temperature between 2000°C to 2600°C under vacuum or inert atmosphere to form very dense products. Silicon carbide tube and parts can be formed by casting, dry press, extrusion, isostatic press and injection moulding. Various complicated shapes can be formed by these process technologies. Due to its very fine gain size and high density, sintered alpha silicon carbide product has excellent surface finishing and tight dimensional control that require non or minimum after-sintering.

  • Available Tube Diameter From 3/4″ to 9″ for American size and 20 mm to 150 mm for metric unit.
  • Available Tube Length: From 1″ ( 25mm) To 72″ ( 1828mm).
  • Most items are in Stock and can be delivered in 1-3 days.
  • Sentro Tech also offer volume discount for all listed sizes if order quantity is more than 5 pieces for same size.
  • Please Specify the Tube ID, OD and Length In the Quote Request Form

Sintered Alpha Silicon Carbide Products offer very unique properties which include:

  • High hardness next to diamond.
  • Extremely wear and abrasion resistance.
  • High flexural strength at room or high temperature.
  • Excellent thermal shock resistance due to its low thermal expansion and high thermal conductivity.
  • Excellent corrosion resistance.
  • High temperature resistance.

Typical Application Of Sintered Alpha Silicon Carbide Products

  • Wear and abrasion resistance tube and parts for power industry.
  • Corrosion resistance parts for chemical and paper industries.
  • Oil extraction parts in oil drilling industry.
  • Automotive components, mechanical sealing and sealing ring.
  • Heat exchange tubes.
  • Structure materials and crucible for semiconductor industry.
