Brown Fused Aluminum Oxide BFA

Brown fused alumina is made from high quality bauxite by fusing in an electric arc furnace at high temperature. It has good toughness and high hardness. It is suitable for manufacturing of vitrified and resin bonded tools, and for lapping , polishing , and sand blasting and sand cleaning.
It can be also used to make superior refractory products.

Application Industry : A brasives industry, refractory materials
Abrasive cutting tools, moulds, bulletproof material
To make mechanical parts, all kinds of mold
To do mechanical parts, all kinds of mold
Ceramic grinding tool, high-grade abrasive, abrasive, abrasive belt, organic coated abrasive tool

high purity AL2O3 95%

Q: Where can I buy more than 94 hardness carbide cutter head, welding, the best address in detail, thank you!: I know the downstairs Beijing Tongzhou District Yangzhuang Road No. 22 hospital Deshang with hard alloy salesroom.

Q: What is the difference between tungsten cobalt alloy and YG8 and YG6 series cemented carbide?: YG8.YG6 series alloys belong to class YG alloys. YG8 is softer than YG6 alloy.

Q: I would like to solder a carbide tool now, what materials do you need to ask for specific methods?: Just give you a guide to carbide cutting tools, and you'll see

Q: What is the hardness of cemented carbide?: Different grades, different hardness, usually (86 ~ 93HRA, equivalent to 69 ~ 81HRC);

Q: What cemented carbide does 2gr13 use?: 2Cr13 martensitic stainless steel can be processed by hard alloy YW2, carbide YW2 suitable for heat-resistant steel, high manganese steel, stainless steel and advanced alloy steel and other special difficult to processing steel finishing, semi finishing.

Q: What is the hardness of YG8 cemented carbide?: The hardness of cemented carbide tools is generally between 89~92.8, such as the hardness of YG8 is HRA89, the hardness of YT30 is 92.8, and the hardness of YT15 is 91.

Q: The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason: Difficult to cut material hardness and strength are very high. The tool produces a great resistance to cutting, and the tool is difficult to resist such a large cutting force, so the tool will be damaged.There are solutions:Heat the treated material to reduce the hardness.Replace cutting tools with better machinability.Change the tool angle to resist greater cutting force.Reduce cutting parameters.Change the processing process, such as using EDM

Q: Processing stainless steel 301 milling thickness of about 3 millimeters, with what blade good?: You mainly milling the surface is not refined, there is no need to use that good, in one is YS25, cheap, well, that's it, if there is any good advice to my replies

Q: Tungsten steel could be used to do is hard alloy knife?: You can do all kinds of data of tungsten steel tool, it can be a knife. There is little precision mould

Q: Printing requirements for cemented carbide: Because of its superior properties such as high strength, hardness, excellent wear resistance and oxidation resistance, carbide is widely used in mechanical processing, petroleum mining, mold forming and structural wear-resistant parts and other fields. In the production of cemented carbide, sintering is the most important process. Even if the compacts are the same, different sintering processes have different effects on the properties of the sintered products. For a long time, many researchers have gradually formed a variety of sintering methods in actual production, including vacuum sintering, hot isostatic pressing sintering, vacuum follow-up hot isostatic pressing, sintering, hot isostatic pressing, etc..
