Aluminium Alloy LM-6, which is called 12 percent Silicon- Aluminium alloy in USA, has long been one of the best Aluminium Alloys for the die- casting of large and intricate parts and those having thin- walled sections.

Aluminium Alloy LM-6 is recommended for manufacturing gravity and pressure die cast components for use in various engineering applications.
Aluminium Alloy LM-6 is manufactured with:

  • High purity virgin Aluminium metal having minimum purity of 99.7%.
  • Special high grade quality of silicon metal which is the major alloying element.
  • Fluxes of superior quality for purification, modification, refining and degassing processes.
  • Keeping the percentage of copper content below 0.60 percent of maximum corrosion resistance.
  • Maintaining the percentage of iron content at the optimum level for best results since ductility is proportionately decreased with and increase in iron content.
