Q:Carbide according to the structure of the words, what can be divided into?

Hard alloy is by grade, can be made into all kinds of special-shaped parts

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: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

Q:How can I buy carbide die on the Internet? Who can help?!

The mould made from the same carbide alloy made from Zhuzhou will not be sold.

Q:What kinds of carbides are there? How should we choose in production?

There are three kinds of cemented carbides commonly used: tungsten carbide cobalt carbide (YG), tungsten cobalt titanium carbide (YT) and general cemented carbide (YW).Because of high hardness and good hardness, cemented carbide is suitable for making cutters.

Q:The difference between cemented carbide and tungsten.

Tungsten steel (hard alloy) with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.Also known as tungsten steel, hard alloy, refers to the sintering of the composite materials containing at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide is tungsten steel common components. The grain size of the carbide component (or phase) is usually between 0.2-10 microns, and the carbide grains are bonded together with metal binders. Binder usually refers to metal cobalt (Co), but for some special purposes, nickel (Ni), iron (Fe), or other metals and alloys can also be used. The composition of an undetermined carbide and bond phase is called "grade"".

Q:Why carbide fracture?

Besides the material is very important, different material by using corresponding domestic and imported tungsten steel, it also has the very big difference.

Q:What are the main causes of wear of high speed steel cutting tools and carbide cutting tools?

(1) mechanical wear: the abrasion caused by the friction between the chip and the cutter front, the surface deformation of the workpiece and the sharp friction between the cutter face, called mechanical wear.When the cutting temperature is not too high, the mechanical abrasion caused by this friction is the main cause of tool wear.(2) thermal wear: when cutting, because of the severe plastic deformation and friction of metal, the cutting heat makes the blade hardness decrease, and the wear and tear caused by cutting performance is called thermal wear.It is recommended that the Santak wick tool be used to solve the wear problem.

Q:The difference between cemented carbide YG 15 and yg12

K30 YG8N YG8 14.5-14.9 160089.5 is suitable for cast iron, nonferrous metals and their alloys and non-metallic materials processing, not smooth, rough and discontinuous cutting section of rough planing, rough milling, drilling, reaming hole and deep hole. K30 YG8 YG10X 14.3-14.7 220089.5 is suitable for the production of small diameter micro drill, milling cutter, rotary file etc.. K35 YG10X YS2T 14.4-14.6 220091.5 is an ultrafine particle alloy, suitable for low speed rough turning, milling of heat-resistant alloy and titanium alloy, as cutting knives and taps, saw blades, milling cutters are preferred. K30 YS2T YL10.1 14.91900 91.5 has better wear resistance and bending strength, mainly used for the production of extruded bars, suitable for general drills, cutting tools and other wear-resistant parts. K15-K25 YL10.1 14.52200 YL10.2 91.5 has good abrasion resistance and bending strength, mainly used in the production of extruded rods, made of small diameter micro drill tool, watch the whole processing, and other cutting tools and wear parts reamer. K25-K35, YL10.2, YG15, 13.9-14.2 210087 are suitable for high tensile steel bars and steel tubes under high compression, for upsetting, piercing and stamping tools under larger stresses. YG15 YG20 13.4-13.7 250085 is suitable for production of stamping die, stamping parts, such as watch spring plates of musical instruments; die punching battery shell, toothpaste tubes; stamping die small size steel balls, screws, nuts etc; twist drill bits.

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%).
