¡ºFor abrasive--Brown Fused Alumina¡»¡¡
____RS Brown Fused Alumina is characterized by its high purity, high bulk density, strong self-sharpening, good toughness, ultra-low content of the magnetic materials. It can be made into grinding tools that is characterized by sharp grinding, low heat generation ratio, high grinding rate and few coating in the using course, and the sintering grinding tools that is characterized by deep blue color after firing, without resillage, without rust and so on, RS Brown Fused Alumina is applicable to make ceramic and resinoid high bonded abrasive tools, grinding abrasive and polishing materials, as well as producing the high grade refractory materials.
____At the same time,Ruishi Abrasive Co.,Ltd. can also provide secondary and third sand of brown fused alumina with various levels at low prices, you are welcomed to purchase.
____In order to meet the demands of the refractory industry, We independently develop and produce RS Brown Fused Alumina which is adopted by modern unique technology of smelting and processing under the universities and research institutes¡¯ support.
