FAQ

Is nickel base alloy hard alloy?

There are three kinds of cemented carbides used in machining,:1, YG--- tungsten cobalt alloy products, the YG6 is generally suitable for machining cast iron, roughing non-ferrous metals and their alloys and non metallic material during continuous cutting, interrupted cutting of semi fine fine cars and trucks etc..

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%).

Can CBN wheels grind cemented carbide? Why?

Cubic boron nitride grinding should not hard alloy and non-metallic hard materials in grinding, high temperature, CBN in alkaline aqueous solution will produce a chemical reaction, CBN wheel can be decomposed in 300 DEG C in alkaline solution, can trace decomposition in boiling water, the crystal grains were damaged, so the grinding, can only use oily the cooling liquid, and can not use water-based coolant.CBN wheel grinding for mild steel, heat-resistant steel, high hardness alloy steel precision grinding and finish grinding. The special steel products such as tungsten, molybdenum and cobalt high speed steel, alloy steel, high-speed steel with special grinding, super finishing machining of heat-resistant parts, and other steel quenching workpiece grinding line.

Is there any pollution in the production of cemented carbide?

There is no pollution, the most basic production, carbon dioxide, sulphur dioxide after heating, heavy water generated after, there are also the noise, dust, harmful substances should be there on the edge of it, so do the work people must take the mask ah, ordinary mask should be useless the kind of good filtration mask, good sealing performance should be divided into ordinary medical masks, and senior two. Ordinary medical masks cost is not high, protection is not outstanding; and senior medical masks is surgery the doctor or dentist, pay attention to the fluid barrier, filtration of particles, guarantee in precision work environment with permeability, haze and mean gray dust, haze (Yan Xia) in the air of sulfuric acid, nitric acid and other disorders that cause visual history of haze. The difference between haze and fog is that when the haze occurs, the relative humidity is not large, while the relative humidity in the fog is saturated. (if there is a large amount of condensation, the relative humidity may not reach 100%, it may appear saturated). Sources of toxic particulate matter in cities: first of all, automobile exhaust. Diesel vehicles are the highest standard American imports of medical masks, such as Beijing work guard Xin, filter good, not only anti particles, but also anti droplets.

suitable for processing the whole alloy drilling, milling, reaming and other cutting tools. This alloy tungsten, cobalt content, how many of you?

Just found the carbide under YK15, its cobalt content in 10%.According to its brand, YK15 should be used to process cast iron, so the main ingredient should be WC+Co.So its WC component should be in 89-90% (just for inference, for reference only)Based on the molar mass of WC, the mass fraction of the W content is deduced

Hello, what's your company? What do you do with carbide? Thank you in advance

Our company is the manufacturer of woodworking knives, made of carbide alloy circular saw blades and forming tools.

Is there a material that is more wear-resistant than cemented carbide and has a relatively low cost?

If it is numerical control tool, it is more wearable than cemented carbide: ceramic, CBN, diamondAmong them, the lowest price of ceramics, diamond prices are highest

What are the grinding carbide wheels?

Diamond grinding wheel, carborundum wheel and so on.The diamond wheel: the diamond abrasive were used as raw materials, metal powder, resin powder, ceramic and metal plating as binder, made of the central circular hole is called consolidation abrasive diamond wheel (alloy wheel).
