棕刚玉俗称金刚砂，是以优质铝矾土、无烟煤、铁屑为主要原料，在电弧炉内经2000高温冶炼制成，经磨机、粉碎、整形、磁选去铁、筛分成多种粒度，外观呈棕褐色，韧性好，显微硬度1800-2200Kg/mm2，体积密度3.85g/cm3，耐高温、耐火度高达1850，可做耐火材料，也可用作磨料。

      棕刚玉具有纯度高，质地致密，栈积密度大，自锐性强，韧性好，磁性物含量低的特点，用其制成的磨具磨削锋利，发热率低，磨削比高，且使用时沾附少，制成的烧结磨具具有烧成后颜色深蓝，不起网状裂纹的特色，用于制造陶瓷、树脂高固结磨具、研磨抛光等。

    （1）由于有耐高温、耐腐蚀、高强度等性能，故用浇钢滑动水口，冶炼稀贵金属、特种合金、陶瓷、炼铁高炉的内衬（墙和管）、理化器皿、火花塞、耐热抗氧化涂层。

   （2）由于有硬度大、耐磨性好、强度高的特点。在化工系统中，用做各种反应器皿和管道，化工泵的部件；做机械零部件、各种模具，如拔丝模、挤铅笔芯模嘴等；做刀具、模具磨料、材料、人体关节、密封模环等。

   （3）刚玉保温材料，如刚玉轻质砖、刚玉空心球和纤维制品，广泛应用于各种高温炉窑的炉墙和炉顶，既耐高温又保温。

      一级棕刚玉：呈现棕红色、黑色颗粒状，主要用于精密铸造、耐磨材料，对磨料要求较高的行业，比如砂轮制造精抛，棕刚玉砂轮是磨削加工中 主要的一类磨具。砂轮是在磨料中加入结合剂，经压坯、干燥和焙烧而制成的多孔体。由于磨料、结合剂及制造工艺不同，砂轮的特性差别很大，因此对磨削的加工质量、生产率和经济性有着重要影响。砂轮的特性主要是由磨料、力度、结合剂、硬度、组织、形状和尺寸等因素决定砂轮种类繁多。

      二级棕刚玉：黑色颗粒状，主要用于喷砂、抛光、研磨、防腐除锈、石材雕刻、纱布材料、切割片等。比如工件表面的清理、工件表面涂覆前的前处理、改变工件的物理机械性能、工件表面的光饰加工。

      三级棕刚玉：黑色颗粒灰色粉状，可适用于各种地面所需地坪砂。比如飞机场跑道、操场、以及工厂用耐磨地坪。

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.
