Q: Carbide yk20? What do you mean?: Cemented carbides YK20, Y represent alloy categories - tungsten cobalt, K20 represents cobalt contentDensity g/cm3:14.30-14.60;The hardness of HRA is more than or equal to 86.5;The shear strength is greater than or equal to N/mm2:2350,Performance and usage: with high toughness and wear resistance, suitable for embedding percussive rotary drilling bit, drilling in hard and tight hard rock.

Q: What is the difference between hard alloy and steel: Cobalt (Co) is used in bonding in the alloy, is in the process of sintering, it can make the tungsten carbide (WC) powder and tightly surrounded Bonded together, after cooling, became hard alloy. (equivalent to the cement content). Usually: 3%--30% tungsten carbide (WC) is the main component of some metal properties of the hard alloy or cermet, the total composition of 70%---97% (weight ratio) is widely used in wear-resistant, high temperature resistance, resistance corrosion, bad working environment of the parts or tool, cutter tools.

Q: What is the specific gravity of cemented carbide?: The carbon content of WC theory is 6.128% (atom 50%). When the carbon content of WC is greater than the theoretical carbon content, the free carbon (WC+C) appears in WC. The existence of free carbon leads to the growth of WC grain around it, resulting in uneven grain of cemented carbide. General requirements of tungsten carbide compound carbon high (more than 6.07%), free carbon (less than 0.05%), the total carbon depends on hard alloy production process and use scope.Under normal circumstances, the total WC carbon content in the vacuum sintering process of the paraffin process is mainly determined by the combined oxygen content in the block prior to sintering. An oxygen content should be increased by 0.75 parts of carbon, that is, WC total carbon, =6.13%+ oxygen content,% * 0.75 (assuming the sintering furnace is neutral atmosphere, in fact, most of the vacuum furnace is carburizing atmosphere, and the total carbon content of WC is less than the calculated value).At present, China's total carbon content of WC is roughly divided into three kinds: paraffin process, vacuum sintering, the total carbon content of WC is about 6.18 + 0.03% (free carbon will increase). The total carbon content of WC for hydrogen sintering of paraffin process is 6.13 + 0.03%. For rubber process, WC total carbon =5.90 + 0.03% is used for hydrogen sintering. The process is sometimes interleaved, so the determination of WC total carbon should be based on specific circumstances.

Q: Big brother on the 1 floor is exaggerating. It's impossible at all: If it needs higher precision, it can only be machined with internal thread grinding machine. It can be used for grinding different specifications of thread, and the efficiency is higher than that of electric pulse, and the size is goodSpecific processing, you can contact me in detail

Q: Carbide products which are used more?: Sealing rings in the sealing industry, mould industry, machine tools, milling cutters, drill bits in the mining industry, and armor piercing shells in the army, etc.

Q: Will the alloy produced at 400 watts be decarburization or carburizing?: This is not necessarily, the hard alloy sintering infiltration decarburization mainly in wet grinding your ingredients and carbon sintering process control, vacuum furnace gas in order to prevent the reaction of pure, alloy with oxygen in the air, infiltration and decarburization products have no direct relationship, of course if it is caused by the leakage of vacuum sintering furnace can not meet the requirements, will lead to the direction of decarburization alloy.

Q: What are the fields of nano WC Cemented Carbides applied?: (2) electronic industry. The development trend of electronic products is miniaturization, integration and precision. The integrated circuit board is made of epoxy resin, glass fiber or glass fiber reinforced plastic. This requires micro drill has high hardness and wear resistance; while the drill diameter is very small (generally 0.2 ~ 0.3mm, and 0.05mm), easy to break, also called bit has high strength and toughness, and need to correct drilling hole position accuracy, and the drill bit has high stiffness (elastic modulus). These conflicting requirements. The common hard alloy and fine grain carbide drills are difficult to meet these requirements, only the use of nano grain carbide grain size of less than 0.5 m. And as the dot printing needle, its diameter is only 0.2-0.35mm; multi frame processing integrated circuit lead by the progressive die, punch thickness less than 0.2mm, the error is only 0.002mm; in addition to the printed circuit board with wire cutting head disc cutter, and the precision of the small die, all require the use of Nanocrystalline WC cemented carbide in order to achieve its function to produce alloy.

Q: What is the difference between hard alloy steel and high speed steel?: 1, two kinds of material composition is different: the former WC+Co+TiC, etc., the latter is generally C+Cr+W+Mo+v2, forming methods are generally different: hard alloy is powder metallurgy process (of course, some are powder metallurgy high speed steel)

Q: What are the carbide inserts on the turning tool welded to the handle?: The first copper burned in the post, and then the borax fell on the top, then put on top of the alloy blade, borax fell on the alloy blade above the flame cutting with money. Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly. Let him cool naturally,
