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

Q:Classification of Cemented Carbides
1 tungsten cobalt carbide2, tungsten, titanium and cobalt carbide3, tungsten, titanium, tantalum (niobium) carbide
Q:Fuzhou where to buy steel tungsten carbide
How will you buy the blade right I can express to you
Q:Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?
Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.
Q:What is the base material of carbide saw blade?
Carbide saw blades include the kinds of alloy cutters, matrix materials, diameter, tooth number, thickness, tooth shape, angle, aperture and so on. These parameters determine the machining ability and cutting performance of saw blades. In selecting the saw blade, it is necessary to select the saw blade according to the kind, thickness, sawing speed, cutting direction, feeding speed and width of saw.
Q:What kind of cemented carbide is used for processing HRC40 degrees stainless steel?
This kind of hardness stainless steel is martensite, hardness is high, use tungsten cobalt class (do not use tungsten, cobalt, titanium, this is attention 1), and carbide containing Ta. Such as: YA6, YH1, YW3, etc.. This kind of steel is of high hardness, small feed rate, lower cutting speed, greater cutting depth, and avoiding the work hardening of the surface leather and the front working procedure (Notice 2). Machine tools. The steel of the tool is better. The coolant selects viscous and chlorine - containing cooling liquid with good adhesion and cooling performance. (Note 3)
Q:Is hard alloy magnetic?
Iron, cobalt, nickel, or iron, cobalt, and nickel are mixed together..
Q:Machining center 8 mm carbide cutter processing 45 steel, how to set the speed, feed, and moving speed?
Faster, two RPM 1 mm, too fast, with G96 RPM feed 0.2 below
Q:How to distinguish the authenticity of Zhuzhou diamond brand cemented carbide blade?
Zhuzhou diamond brand cemented carbide blade is the first brand in our country. We can distinguish its authenticity from the following aspectsVisual package: it is packed in plastic box, the upper and lower cover are transparent plastic, and the bottom box is blueNormative labels: according to the ISO standard, lists the recommended types of processing materials, bar code identification, marked "diamond brand" trademark and "China well-known trademark" and enterprise logoType anti-counterfeit: each piece of hard alloy welding machine, clamping blade convex superscript "ZCCT" logo, direct press formingSealing anti-counterfeiting: labels and sealing paste affixed to the interface of the packaging box, one-time paste, can not be pasted after tearingZhuzhou Jing Jing carbide sales Co., Ltd.
Q:What are the features of cemented carbide YG8 knives?
Density: 14.6-14.8; hardness HRA:90.5; flexural strength, Mpa2300High bending strength, shock resistance and vibration resistance is better than YG6. It is suitable for low speed rough machining of cast iron, non-ferrous metals and their alloys, and non-metallic materials
