Description: Pink fused alumina is electrically fused in high temperature, being added with the right quantity of oxidized chromium. It is pink. Its hardness is close to, but toughness higher than that of wa. The abrasive tools made of it feature excellent durability and high processing cleanness, which are suitable for the precision grinding of the measuring tolls, lathe main shafts, instruments and apparatus parts, threading work pieces and samplers, etc. Usage: 1. Pink fused alumina is generally for hardened steel, alloy steel armor and workpiece grinding. 2. Pink fused alumina is suitable for precision grinding of measuring and instrumentation components. 3. Pink fused alumina is also suitable for form-products grinding. 25kg small bag, 40 bags in one big bag.

Single crystal fused alumina Single crystal aluminum oxide (sa) for abrasive material /single crystal aluminum oxide /sa 32a /mono-crystalline fused alumina Single crystal fused alumina is a kind of abrasive produced by fusing calcined alumina by the bayers process in the producing process. And then by crushing and sizing to desired grain size. Single crystal fused alumina has high hardness and unique micro fracturing containing of well grown micro crystalline structure. Single crystal fused alumina generates many new cutting edges. It is suitable for a wide variety uses from gerneral grinding to precision grinding of high hardness tool steels. 25kg small bag, 40 bags in one big bag.

1.Production introduction White fused alumina is made with an electric furnace from high-grade alumina powder as raw material. The resulting mineral has higher hardness and slightly lower toughness than brown fused aluminum oxide. Characterized by its high purity, strong grinding ability, abrasive tools made of it are suitable for grinding and polishing of cutting tools, precision-castings, spraying and coasting, medium body for chemical industry applications, special ceramics and high-grade refractory materials. Detailed specifications can be supplied on request. 3.Size we manufacture F8, f10, f12, f14, f16, f20, f22, f24, f30, f36, f40, f46, f54, F60, f70, f80, f90, f100, f120, f150, f180, f220, f240, f280, f320 F360, f400, f500, f600, f800, f1000, f1200 4.Performance and advantages 1.

Approximately 50% lighter than metallic media, white aluminum oxide has twice as many particles per pound. The fast-cutting action minimizes damage to thin materials by eliminating surface stresses caused by heavier, slower-cutting media blasting grits. White aluminum oxide blasting media has a wide variety of applications, including cleaning engine heads, valves, pistons and turbine blades in the aircraft and automotive industries. White aluminum oxide is also an excellent choice for preparing a hard surface for painting. White aluminum oxide contains less than 0.2% free silica and is therefore safer to use than sand. The grit size is consistent and cuts much faster than other sand blasting media, leaving a smoother surface. 25kg small bag, 40 bags in one big bag.

1. Description White tabular alumina is a kind of pure sintered corundum, which is sintered and completely shrink without adding any additive, such as mgo or b2o3, with coarse crystals and well-developed alpha al2o3 crystal structure. The tabular crystal structure is characterized by narrow pores, with more closed porosity, almost the same apparent porosity compare with fused corundum, high purity, good stability volume density, tiny refiring shrink. After high temperature treatment, tabular alumina is used for refractory and castable characterized by good thermal shock stability and flexural strength. But the price is higher than the other alumina. 2. Performance Tabular alumina is characterized by good heating volume temperature performance and good thermal shock resistance. 3. Usage Tabular alumina is the perfect refractory raw material, which is widely used as the aggregate for producing various alumina refractory, it also can be used in other monolithic refractory. It can replace fused alumina and white fused alumina in some application position, and improve the performance of refractory material. 4.
