Foundry - CUMI EMD Synthetic Fused Alumina | White Fused ...

CUMI’s synthetic fused alumina produced by controlled fusion of special alumina with other raw materials ensure low bulk density (1.7 vs 2.9 g/cc) and high refractoriness (PCE of 18500C +). This material exhibits very low thermal expansion coefficient (7.2x 10 -6 / 0 C) which makes it a perfect substitute for zircon sand in foundry application.
