Features & advantages of Bauxite for Foundry and Casting

  Bauxite as a refractory materials can be used in foundry and casting industry, 

  there are few features and advantages for why it can be.

  1. Lower thermal expansion rate and thermal conductivity:

  It is just this characteristic that makes the foundry more precisely, less cracking and high output.  

  Also can improve foundry quality.

  2. Lower cleavage breakage rate: It has high density and has very low cleavage breakage rate. 

  Easily reclaimed that makes it more protect environment for the less sand powder occurred.

  3. High refractoriness and service temperature: Major element is Al2O3 that has very good refractoriness.
