Advantages of cast iron


Due to the casting process and the fine-grained dense microstructure Tasso cast iron bars have a number of built-in advantages compared to traditional sand castings or steel:

  • Uniform fine-grained structure free from gas-holes, sand and other tool-wearing inclusions
  • Virtual elimination of common casting defects like shrinkage and porosity
  • Improved machinability from the same Brinell hardness compared to alternative materials
  • Reduced scrap rate and 100 % recyclable surplus material
  • Excellent surface finish suitable for coating or painting
