五金工具抛光 黑刚玉

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。

黑刚玉物理性能指标：

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首选材料。

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最低的呢，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实惠做出来的路面防滑效果又好，所以很多人在做防滑路面时都首先考虑选用黑刚玉。

黒刚玉包装及储运：

白色编织袋包装，净重：25kg。运输储存期间防止包装破损，以免漏失或混入杂物．不宜与承托料及其他滤料一起运输堆放。

Brief introduction of black corundum:

Black corundum also known as low aluminum corundum, blue corundum, is in the electric arc furnace, bauxite smelting and an AL2O3 and iron ore spinel phase mainly black crystal, which is characterized by low content of AL2O3, and have a certain amount of Fe2O3 ( 10%), which has moderate hardness, toughness, from the sharp, good adhesion, high durability, grinding less heat, high temperature resistance, is not easy to scratch the surface of the workpiece, the workpiece surface finish higher characteristic.

Black corundum price:

In abrasive products, corundum, white corundum, Kurotake Ok is the same with bauxite as main raw material, add iron in high temperature in electric arc furnace smelting and become, why black corundum price at which is the lowest, in the market price of aluminum than iron price per ton higher than many, corundum sand three oxygen two aluminum content of 95% or more, while black corundum sand three oxygen two aluminum content reached only 85%, this can be seen on the reasons for the low price of black corundum.

Black corundum low price but in polishing, sandblasting effect is very good, it is excellent in slip on the ground both affordable made out of pavement skid resistance and good effect, so a lot of people doing road are the first consider the selection of black corundum.
