High refractoriness and high collapsibility with less burn-on. High refractoriness and high collapsibility with less burn-on.
低热膨胀,提高铸件精度 Reduced thermal expansion improving casting dimensional accuracy
圆球度高,透气提高表面光洁high sphericity and surface luster improving permeability
Lower density decreasing cost and increasing benefit
Strong abradability helps to increase recycling and reduce emissions
