Washington Mills: Mullite for Investment Casting

Press release date: July 12, 2014

Weight of Your Investment Cast Shell Got You Down?

If you are concerned that your investment cast shell might be too heavy, take some weight off by switching your raw material to DURAMUL - Washington Mills' fused mullite.

Washington Mills fused mullite has:
Lighter weight than alumina and zircon
Excellent thermal shock resistance
High purity to eliminate contamination & maintain high use temperature
High strength

A heavier shell requires more energy in drying and firing and is less efficient than one made of fused mullite. Please call us to today to learn more about our DURAMUL product and how fused mullite can be used to lighten your investment cast shell without compromising its strength. Contact Washington Mills at or 800-828-1666.
