白剛玉


白剛玉磨料,白剛玉,白剛玉塊,白剛玉磨具,白剛玉砂(WA)
白剛玉磨料是以氧化鋁為原料,經高溫熔煉而成。呈白色,硬度比棕剛玉略高,韌性稍低。用白剛玉制造的磨具適用于高碳鋼、高速鋼和淬火鋼等的磨削。白剛玉磨料,亞白剛玉磨料可作研磨拋光材料,還可作精密鑄造型砂、噴涂材料、化工觸媒載體、特種陶瓷、高級耐火材料等。
白剛玉磨料性能:白色、較棕剛玉硬而脆,切削力較強,化學穩定性好,具有很好的絕緣性。
白剛玉磨料適用范圍:可做固結構及涂附磨具,濕式或干式噴射砂,適合晶體、電子行業的超精研磨和拋光及制作高級耐火材料等。適合加工淬火鋼、合金鋼、高速鋼、高碳鋼等硬度較硬,抗張強度較大的材料。白剛玉磨料還可用做觸媒體,絕緣體以及精密鑄造砂等。
WHITE FUSED ALUMINA(WA)
Its main raw material is abayer alumina,which is electrically fused in high temperature.It is white and its hardness is higher,but toughness lower than that of brown fused alumina.The abrasive tools made of it are suitable for the grinding of high carbon steel and chilled steel.It can also be usedd as polishing materials and precision founding sand,spraying and coating materials,catalyst carrier,special ceramics and super refractory materials.
Property:IT is white and hard and more brittle than A.It features strong cutting force and steady chemical property and excellent insulation.
Usage:It can be used for making bonded and coated abrasive tools,wet or dry blasting.It is also sutable for super precision grinding and polishing of crystal and electronic industry and making high quality refractory materials.It can be adopted for the grinding of the hard and strong bending stength materials such as chilled steel,alloy steel,high-speed steel and high carbon steel.Meanwhile,it can be used as catalyse carrier,insulator and presicion founding sand,etc.
