150,180,200,220目白
刚玉1.以工业氧化
铝粉为原料，于电弧中经2000度以上高温熔炼制成，经粉碎整形，磁选去铁，筛分成多种粒度，其质地致密、硬度高，粒形成球状，
白刚玉适用于制造陶 瓷、树脂固结
磨具以及研磨、抛光、喷砂、精密铸造等，还可用于制造高级
耐火材料，代号“WA”于国际通用标准、国家标准一致，多数供出口，也有一定量供应国内用户。
White fused alumina was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
2. 1、不影响加工件的颜色;
2、可在严禁铁粉残留的制程使用来喷砂;
3、微粉级非常适合湿式喷砂和研光作业;
4、加工速度快品质高;
5、所含
氧化铁的量极低适合严禁铁质残留之喷砂作业;
6、经过酸洗步骤以除
