黑刚玉简介:
黑刚玉又名低铝刚玉、青刚玉,是于电弧炉中,将铝矾土熔炼而制得的一种AL2O3和铁尖晶石为主矿相的灰黑色结晶体,其特点是AL2O3含量较低,并有一定量的Fe2O3(10%)存在,因而具有硬度适中、韧性大、自锐性、粘结性良好,耐用度高,磨削时发热少,耐高温,不易划伤工件表面,工件表面光洁度高等特点。

黑刚玉用途:
黑刚玉主要应用于自由研磨,如金属零件电镀前底面抛光、铝制品,适用于自行车、摩托车、缝纫机、钟表零部件、灯饰、塑胶及五金工具等的抛光,亦适用于喷砂(除锈、玻璃喷花),加工材料,制造树脂切割片、角磨片和涂附磨具等。黑刚玉粒度砂和微粉特别适合于不锈钢工件的研磨抛光及油石、研磨膏的制造,黑刚玉段砂更是防滑路面和煤矿坑下仓储的材料。
黑刚玉价格:
在磨料产品中,棕刚玉、白刚玉、黑刚玉同样都是以铝矾土为主要原料,加有铁屑在高温电弧炉中熔炼而成的,为什么黑刚玉的价格在其中是***的呢,在市场上铝的价格比铁的价格每吨要高出好多,棕刚玉一级砂的三氧二化铝的含量在95%以上,而黑刚玉一级砂的三氧二化铝含量才达到85%,在此就可以看出黑刚玉价格低的原因了。
黑刚玉的价格低但是在抛光、喷砂效果都是很好的,优其是在做防滑地面上既便宜又实惠做出来的路。

about for a long time:
【Gongyi long polishing abrasive factory is located in the songshan 】 north - gongyi city, which the provincial capital zhengzhou, east west the ancient capital of luoyang, the south out of shaolin, surging the Yellow River to the north, this 310 national road, longhai railway arteries (huoerguos) (lianyungang) - even huo highway huanshi line! Tang dynasty poet du fu's hometown, the northern song dynasty big seven emperor eight ling tomb complex, floating mountains snow hole play more here add tenshi national color, full of poetic and leisurely spectacular! Gongyi city long polishing abrasive factory welcome to our factory website, very glad to you met on the Internet, whether in the past, we have cooperation, hope we become friends, the company with the best quality and the most preferential price of spot supply.
Black corundum profile:
Black corundum and low aluminum corundum, blue corundum, is in the electric arc furnace, the bauxite made by melting a AL2O3 spinel is given priority to with iron ore in the colored crystals, its characteristic is AL2O3 content is lower, and there is a certain amount of Fe2O3 (10%), and therefore, moderate hardness and great toughness, self-sharpening, good bonding, high durability, produce less heat when grinding, high temperature resistant, not easy to scratch the surface of workpiece surface finish.
Black corundum physical performance indicators:
Project refers to the standard project refers to the standard
Yan color black highest use temperature (1850 ℃)
Crystal shape trigonal system real density (g/cm3) p 3. 50
9.0 linear expansion coefficient (mohs hardness) or greater (0-1600 ℃) 7-9
Melting point (2050 ℃)
Black corundum chemical indicators:
Specifications of main chemical composition %
Al2O3Fe2O3SiO2TiO2
Level 1, 856-95-82-4
2 < 80 > 9 8 > > 4
Black corundum purposes:
Black corundum is mainly applied in the free abrasive, such as floor polishing before plating metal parts, aluminum products, apply to a bicycle parts, motorcycle, sewing machines, watches and clocks, lighting, plastic and hardware tools such as polishing, and is also suitable for sandblasting (spray cleaning, glass flower), materials processing, manufacturing resin cutting disc, Angle grinding, and coated abrasive such as attached. Black corundum sand granularity and micro powder, especially suitable for grinding and polishing stainless steel workpieces and sharpening stone, grinding paste, black corundum sand is the antiskid pavement and coal mine under the storage and the material of choice.
Black corundum price:
In abrasive products, brown corundum, white corundum, black corundum is same bauxite as main raw materials, added with scrap iron smelting in electric arc furnace at high temperature, and why the black corundum is the lowest price in it, in the market of aluminium prices are much higher than the price per ton of iron, brown corundum sand level three oxygen two aluminum content above 95%, while black corundum sand level three oxygen two aluminum content is 85%, and in this you can see the black corundum price low.
Black corundum price is low but the polishing, sand blasting effect is very good, optimized its non-slip floor is doing make cheap and affordable way.
