? ? ?棕剛玉俗稱金剛砂，是以優質鋁礬土、無煙煤、鐵屑為主要原料，在電弧爐內經2000高溫冶煉制成，經磨機、粉碎、整形、磁選去鐵、篩分成多種粒度，外觀呈棕褐色，韌性好，顯微硬度1800-2200Kg/mm2，體積密度3.85g/cm3，耐高溫、耐火度高達1850，可做耐火材料，也可用作磨料。
?
? ? ? 棕剛玉具有純度高，質地致密，棧積密度大，自銳性強，韌性好，磁性物含量低的特點，用其制成的磨具磨削鋒利，發熱率低，磨削比高，且使用時沾附少，制成的燒結磨具具有燒成后顏色深藍，不起網狀裂紋的特色，用于制造陶瓷、樹脂高固結磨具、研磨拋光等。
?
? ??（1）由于有耐高溫、耐腐蝕、高強度等性能，故用澆鋼滑動水口，冶煉稀貴金屬、特種合金、陶瓷、煉鐵高爐的內襯（墻和管）、理化器皿、火花塞、耐熱抗氧化涂層。
?
? ?（2）由于有硬度大、耐磨性好、強度高的特點。在化工系統中，用做各種反應器皿和管道，化工泵的部件；做機械零部件、各種模具，如拔絲模、擠鉛筆芯模嘴等；做刀具、模具磨料、材料、人體關節、密封模環等。
?
? ?（3）剛玉保溫材料，如剛玉輕質磚、剛玉空心球和纖維制品，廣泛應用于各種高溫爐窯的爐墻和爐頂，既耐高溫又保溫。

? ? ? 一級棕剛玉：呈現棕紅色、黑色顆粒狀，主要用于精密鑄造、耐磨材料，對磨料要求較高的行業，比如砂輪制造精拋，棕剛玉砂輪是磨削加工中 主要的一類磨具。砂輪是在磨料中加入結合劑，經壓坯、干燥和焙燒而制成的多孔體。由于磨料、結合劑及制造工藝不同，砂輪的特性差別很大，因此對磨削的加工質量、生產率和經濟性有著重要影響。砂輪的特性主要是由磨料、力度、結合劑、硬度、組織、形狀和尺寸等因素決定砂輪種類繁多。
?
? ? ? 二級棕剛玉：黑色顆粒狀，主要用于噴砂、拋光、研磨、防腐除銹、石材雕刻、紗布材料、切割片等。比如工件表面的清理、工件表面涂覆前的前處理、改變工件的物理機械性能、工件表面的光飾加工。
?
? ? ? 三級棕剛玉：黑色顆粒灰色粉狀，可適用于各種地面所需地坪砂。比如飛機場跑道、操場、以及工廠用耐磨地坪。

Brown corundum, commonly known as carborundum, is a high quality bauxite, anthracite coal, scrap iron as the main raw material, made in the Canon of 2000 high temperature smelting electric arc furnace, the grinding mill, crushing, plastic, magnetic separation to iron, the screen is divided into a variety of particle size, appearance is tan, good toughness and microhardness, 1800-2200 kg/was, acuity 3.85 g/cm3 volume density, high temperature resistance and refractoriness is as high as 1850 , can be used as refractory material, also can be used as an abrasive.
Brown fused alumina with high purity, dense texture, bulk density is big, the sharpness is strong, good toughness and the characteristics of the content, low magnetic material, made of its sharp abrasive grinding, low heating rate, high grinding ratio, and when using cleave, made of sintered abrasive has burnt after dark blue color, not reticulate crack characteristic, used in the manufacture of ceramics, resin high consolidation abrasive, grinding and polishing, etc.
Primary corundum: palm red, black, granular, is mainly used for precision casting, wear-resisting material, the higher requirements for abrasive industry, such as grinding wheel manufacturing fine buffing, brown corundum grinding wheel in grinding is the main type of grinding tool.In abrasive grinding wheel is to join the binder, the compact, drying, and roasting, made of a porous body.Because of the different abrasive, binder and manufacturing technology, the characteristics of the grinding wheel difference is very big, so the quality of grinding machining, productivity and economy has an important influence.The characteristics of the grinding wheel is dominated by abrasive, strength, binders, hardness, organization, there are many different kinds of shape and size and other factors determine grinding wheel.
Secondary corundum: black granule, mainly used for sanding, polishing, grinding, anti-corrosion derusting, stone carving, gauze materials, cut pieces, etc.Such as cleaning, surface coating on the surface of the workpiece before processing, change the physical and mechanical properties of the workpiece, workpiece surface finishing processing.
Level 3 corundum: black particles gray powder, can be applied to all kinds of ground floor sand required.Such as airport runways, playground, and factory use wear-resisting flooring.
