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:Import all carbide drill bit, mainly those brands

Good (maford), Kenna, Thomas, di tex, Sandvik, guhring general in the domestic production, the performance of discount.Now on the market is generally a bit alloy steel material whole bit, although the materials are the same, but due to the processing technology, various brands of product quality disparity. Imported and domestic alloy drills are also very different.Imported alloy bit usually adopts VHM micro grain hard alloy (ISO K40), the type of ultrafine particles (0.6 m) in the application of high performance drill and ordinary milling machine, the hardness and toughness of the ideal together.Take high quality alloy bit surface coating, such as chromium aluminum nitride (AlCrN) coating, the coating layer of coating, the thickness of 4 m, the micro hardness is up to 3200HV, the friction coefficient of 0.35, thermal stability up to 1100 degrees celsius. After coating, the drill color is bluish gray.After coating, the alloy drill can process low alloy steel and high strength steel. High steel can reach 54HRC.

Q:Hard alloy die polishing with what can be reached Ukraine black brightness

What if this need to die, the smaller diameter must be black if the large diameter is bright, with a diamond grinding paste and polishing powder

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:Several hard alloy cutter lathe with?

YG car, pig iron and so on, YT, steel and the like, high temperature resistant, YW car alloy steel, the highest strength.

Q:I want to process more hard stainless steel, with YC45 this type of carbide knife can do? Where can I buy authentic, know the friend told me, thank you

If it is stainless steel (316 or 304), it is recommended that you use YG8 alloy cutter head, processing needs low speedWith sufficient cutting fluid, this stainless steel does not require any other cutting tools.Note: YG8 impact resistance, but not high temperature

Q:What are the meanings of cemented carbide codes, such as YW, YS30, YN10?Which company made its own brand? What is the composition?

Hard alloy is one of the people familiar with the tools and materials, it is very difficult to weld by hard metal carbides (we, Tie) of powder metallurgy with CO, MO and NI as sintering binder. Its mechanical, physical and mechanical properties depend mainly on the kinds of metal carbides, properties, quantities, grain sizes, types and components of binders.In cemented carbides, the proper addition of Tie increases the content of hard Tic, and the higher the hardness of the alloy. The more the content of cobalt in the bonding phase, the lower the hardness of the alloy. Therefore, the hardness of We-Tie-eo alloy is higher than that of We-eo alloy. The hardness of We-eo alloy can be increased by adding Tae or Nbc. The higher the hardness of the cemented carbide, the better the wear resistance, but the lower the strength (bending), and the addition of Tac will improve the blade strength, while strengthening the blade resistance to fragmentation and breakage, fatigue strength also increased. Generally, the higher the hardness, the lower the toughness. In China's Cemented Carbide standard YB850-75, most carbide grades are We-Co (YG) and We-Tie-Co (YT) two.Domestic hardness alloy grade control: GB, brand ISO, P10, P20, M10, M20, K01, K10, K20, K30, domestic uniform brand YT15, YT14, YT5, YW1, YW2, YG3, P30, YG6x, YG6, YG8

Q:What material is that ultrafine cemented carbide?

The main component of cemented carbide is tungsten carbide, so also known as tungsten steel, tungsten steel belongs to hard alloy, also called tungsten titanium alloy. The hardness can reach HRB89 to 95Tungsten steel production process is as follows: the powder is pressed into a blank, and then into the furnace heated to a certain temperature (sintering temperature), and keep a certain time (time), and then cooled down to obtain the required properties of tungsten materials.The characteristics of ultrafine cemented carbide is the main component of WC, compared to the hard phase and general hard alloy, the hard phase particles are very fine (average grain size less than 1um), so you can get a higher than the general hard alloy of the same hardness strength (toughness), edge grinding can be sharper and better wear resistance.

Q:Dalian enterprises now need 16.3 and 19.3 mm in diameter, the whole cold hard alloy bit, where can I find buyers? Leave a contact

I know Zhuzhou Hua tungsten seems to have what you need. I suggest you go to see their company

Q:How to distinguish the authenticity of Zhuzhou diamond brand cemented carbide blade?

In fact, now only look at the packaging has been unable to identify, because now the copycat alloy packaging has really not with what two things, want to know after the authenticity can be used, you can try to buy a small amount of alloy, the quality of clearance to buy a lot, you can go to the station to find the Alibaba China @ Rui Sen # trade. Easy% Co., reputation has been good, but sales of hard alloy Zhuzhou diamond factory, there are quality problems can return shipping.
