Surface Coating Semi-friable Aluminium Oxide
Code:FA
FA is one of the corundum series products which was successfully developed by Shandong Luxin High-tech Industry Co., Ltd. (formerly known as Sisha Co., Ltd.) in the year of 2000. Brief introduction as follows:
Combining some advantages of both Brown Alumnium Oxide and White Aluminium Oxide, FA is one of the high-end corundum series new products. It is another new type abrasive grains with wide range of applications after A, WA, ZA, and PA. It has its own unique grinding performance. We can treat its grains surface by coating and high-temperature calcination, loose sieving, which can improve the grains surface roughness and increase its hydrophilia. We are the first creator for this method in China.
With its reasonable toughness and excellent self-sharpening performance, FA can be used for making ceramic abrasive tools, resin abrasive tools and coated abrasives. The bonded abrasives made by FA are featured of high durability, excellent self-sharpening performance and retainability. When processing some workpieces under the same conditions, the surface quality of the workpieces, processing efficiency as well as durability of the abrasive tools are all much better than those of abrasive tools made by A, WA, PA and single crystal Aluminmium Oxide (code SA). Compared to BA or WA grinding wheels, the workpieces processed by FA grinding wheels are double for every dressing. And compared to PA and SA, it can improve 10%-30%, or reach their same result. For rough grinding, FA can improve processing efficiency; and for fine grinding, FA can improve the workpieces' surface quality.
The bonded abrasives made by FA can be used for processing ordinary steel, bearing steel, all kinds of stainless steel, tool steel, low Cr,W,Mo,V,Co content special alloy steel, some types of cast iron and all kinds of non-ferrous metals, such as, aluminium alloy containing Cu, Ni and Mg, copper containing S and Zn, magnesium alloy containing Al and Zn, etc.
The coated abrasives made by FA has excellent high quality, long service life, and larger grinding quantity. It is mainly use for thermosensitive metal and alloy, soft non-ferrous metal, etc. It is can be also used for sanding wood, plastic coating, paint. Especially for hard wood, the result is much better. Because the bulk density of P grits of FA is lower, the interparticle space is enough to avoid clogging by swarf, which can get anti-clogging and cooling result.

The predecessor of Shandong Luxin High-tech Industry Co.,Ltd. (following named Luxin High-tech) was Sisha Co.,Ltd. which was the first abrasive grains and tools enterprise in China invested and built by the state in 1950 and regrouped and reregistered in April 2011.At present it is the leader enterprise in abrasive grains and tools industry in China. It is located in , Province. It owns four major industries, which are abrasive grains,abrasive tools, coated abrasives and sanitary ware. It is the wholly owned subsidiary of Luxin Venture Capital Group Co.,Ltd. whose stock code is 600783.
From a small factory manufacturing electrode by hands,to a trans-regional and multi-industry modern enterprise group, from the No.4 Grinding Wheel Factory,and then Sisha Co.,Ltd., to Shandong Luxin High-tech Industry Co.,Ltd.,the company contributed much to the state economic construction and abrasive grains and tools industry in . Since the reform and opening-up,Luxin High-tech completed and perfected its relatively independent and complete abrasive grains and tools research and development system,manufacturingsystem and test system.It has already been an advanced enterprise in abrasive grains and tools industry in the world.
The company’s products, White Aluminium Oxide, Pink Aluminium Oxide,and bonded abrasives, were all awarded the Famous Brand in abrasive grains and tools industry in China.Ceramic Microcrystalline Abrasive Grains passed the authenticate of Province Scientific and Technological Achievements and has reached the world advanced level. The wear resistant Aluminium Oxide for laminate flooring which is listed in National Torch Plan Project has reached the Treibacher products quality level,it is the world advanced level. The 1550mm Resin High-speed Cutting Wheel for Hot Steel billet researched and developed by ourselves filled the domestic gaps and has replaced the imported products. The company undertook the scientific and technology major special project--Ceramic Microcrystalline Abrasive Grains and Tools manufacturing technology which is the National Top Grade CNC Machine Tool and Basic Manufacturing Equipment has achieved initial outcome. As the main R&D cooperator,the company participated in research and development the 2012 scientific and technology major special project,high efficiency precision Grinding Wheels for Aero Engine disks/axle/blades parts, and high efficiency precision grinding wheels for car power assemblycritical parts.All these works are in an orderly manner according to the plan.Relying on Luxin Hi-tech, Shandong Abrasive Grains and Tools Engineer Research Center has been built and undertook many research projects from the state, province and city. The company won 2 national awards, 11 provincial awards and 10 city awards.Luxin Hi-tech leading products, Mount Tai Brand, MT brand and Sisha brand abrasive grains and tools, and coated abrasives have listed on Shandong Famous brand for a decade.The enterprise has been rewarded Elaborately Brand-making Activity Top-ten Enterprise and Corundum & Abrasive Tools Top-ten Enterprise for many years.
Luxin High-tech always insists on taking the connotative development as the principle thing, researches and develops top grade produces using in top grade CNC machine tools, high-speed train, aviation and auto, replacing the imported products. It will research and develop and produce ceramic abrasives, precision abrasive micro powder, breaking the domestic market which is long-term monopolized by foreign products. The company firmly believes that abrasive industry stepping in normal development way has the ability to carry the banner of promoting Chinese abrasive industry and to make new contributions to the development of national industry.
