JIS Standard White Fused Alumina for Coated Cloth Abrasives White Fused Alumina Wfa
White Fused Alumina Introduction
Alba alumina conflata (WFA)Est synthetica laesura materia inducens summus puritatemaluminain fornace electrico in calidis temperaturis.Habet structuram crystallinam principaliter compositam ex corundo (Al2O3) et notam eiuseximia duritia, robur, et summa integritas.Alumina alba mixta diversis formis praesto est, inclusogris, harenae et pulverisadhibeturque in variis medicamentis;Molendum et poliendum, Superficies Praeparatio, Refractoria, Subtilitas Iectio, Abrasiva Blasting, Superabrasiva, Ceramica et Tiles, et etc..
