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: Can hard alloy be welded with silver electrode?: Hard alloy can use silver electrode welding, some more liquid silver wire than general tin brass or iron brass, the cost is too high, the strength level than the ordinary copper electrode should be higher, personal suggestions for the selection of copper base up instead of silver electrode, such as the WEWELDING 46 electrode (referred to as Odin Wei 46 If the strength of electrodes), the structure is higher than silver, if it is to achieve the high permeability, it is still the ideal to silver, only from the strength level, is not WEWELDING 46 copper based electrode.

Q: Hard alloy is tungsten?: You can understand that.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Cemented carbides include:Tungsten cobalt carbideThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).

Q: What are the three types of commonly used cemented carbides?: Common brands are YT5 (mass fraction of TiC is 5%), YT15 (mass fraction of TiC is 15%), with the mass fraction of TiC increased, the mass fraction of cobalt decreased, hardness and wear resistance increased, bending strength decreased. This kind of hard alloy is not suitable for processing stainless steel and titanium alloy.K class (equivalent to China's YG class), cemented carbide composed of WC and Co, also known as tungsten cobalt carbide. These alloys are mainly used to process cast iron, nonferrous metals and their alloys. The common grades are TG6 (cobalt mass fraction 6%) and YG8 (cobalt mass fraction 8%).

Q: What kind of material is the alloy drill bit?: Alloy bit generally refers to the hard alloy bit, divided into integral, welded, indexable inserts and replaceable type.The main components of cemented carbide are tungsten carbide, cobalt, etc.,

Q: What is the difference between hard alloy and steel: Products: tungsten steel containing approximately 18% tungsten alloy steel, tungsten steel belongs to hard alloy, also called tungsten titanium alloy. The hardness for the Vivtorinox 10K, second only to diamond. Because of this, tungsten steel products (a common watch), has the characteristics of not easy to be worn. Commonly used in lathe tool, drill, impact drill glass knife head, tile cutter, hard annealing, but brittle. Hard alloy: powder metallurgy hard alloy belongs to the category of metal ceramic is also known as metal carbides (WC, TaC, TiC, NbC, etc.) or metal oxide (such as Al2O3, ZrO2 etc.) as the main ingredient, adding proper amount of metal powder (Co Cr, Mo, Fe, Ni, etc.) made by powder metallurgy method, has some characteristics of metal ceramic.

Q: Hello I remember carbide knives have several classifications As if it were not the same as it is now, can you tell me the same and different models as before? What material can they make?: I remember Zhuzhou Hua tungsten. They have a full range of them. You can go to their Baidu company

Q: Why is Zhuzhou cemented carbide plant called (601) what is this code number? What does it stand for? 601, production of military?I found the Zhuzhou code factories such as: Zhuzhou hard alloy factory (code 601) Zhuzhou Southern Power Machinery Factory (code 331) Zhuzhou vehicle factory (code 430) add code 6+0+1=7 3+3+1=7 4+3+0=7 are equal to 7 this is the 7 to have the meaning or coincidence: I think this is only a manifestation of the planned economy, the factory replaced by code, 601 is not all for military services, which may be affiliated with the Department of it?

Q: Hard alloy and cast iron join together, use temperature 150 degrees, what glue is better to use?: High temperature resistant high strength metal and carbide inorganic adhesive YL04-3. For the structure of all kinds of cutting tools such as bonded &def hard alloy cutter and lengthened drill, geological drill; casting airhole crack repair; use temperature of -196 DEG ~800 DEG

Q: What does "YC20.1 carbide" brand mean?: PriceFor example, the ordinary 20 party 90 degrees welding tool used A320 blade, the price of 11 yuan, non tax written price /20120716 Edition

Q: My uncle is a hard alloy round bar. Can you tell me where to use an alloy round bar?: I have some hard alloy round bars (tungsten steel) and high speed steel round rods (all used for cutting tools). Now I want wire cutting, laser, diamond, wire cutting
