FAQ

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.

What about cemented carbide produced in Zhuzhou? What brand is good?

Is good at home, as for the brand well of course is diamond, refined into a brand is also good, there are fine into hard alloy sales company, previously entered a large red facade, product is very much, the Diamond Road No. 24-5, hope to help to you.

How are cemented carbides sintered?

After cooling, the hardened phases are distributed in a grid of bonded metals that are closely related to each other and form a solid whole. The hardness of cemented carbide depends on the content of the hardened phase and grain size. The higher the content of the hardened phase and the finer the grain, the greater the hardness. The toughness of cemented carbide is determined by bonding metal. The higher the bonding metal content is, the greater the bending strength is.

What is hard alloy steel?

1, generally called carbide, rather than hard alloy steel.2. Cemented carbides are alloy materials made from hard metal carbides and bonded metals by powder metallurgy process.3, carbide hardness is very high, mainly used for cutting tools.By any means, hard alloy is not the hardest material in the world. Diamond is the hardest material. Many inorganic non-metallic materials have higher hardness than cemented carbides.

Can carbide drills be used for high speed steel twist drills?

If not drill quenching steel, or stainless steel material, usually try not to use the hard alloy bit, the reason is that the hard alloy bit is easily broken, unless the non use of the situation, will use the hard alloy bit. The use of high-speed steel drills is sufficient to meet the needs of the job.

What are the fields of nano WC Cemented Carbides applied?

(4) medical application. The drill is a fine medical instrument, the incision must be sharp, but also has good abrasion resistance and toughness, application of ultrafine grain WC hard alloy with high strength, high toughness and wear resistance in this field widely. (5) other applications. Nanocrystalline WC hard alloy because of its fine grain, as the cutting tool can grind the cutting edge radius and high precision, sharp nose arc; because of its high strength can be used for making fine tool rake angle, feed rate and small amount of snacks knife, such as small diameter cutter, reamer etc. because of its high elasticity; modulus and friction wear properties, can be used for the production of high precision mould, punch etc.; also can be used for the production of high wear resistance, erosion resistance, such as high-pressure nozzle, valve, high-pressure gun, glass cutter, cutter and textile tape, tape cutter etc.. In addition, scientists are developing circular tools, rock drilling tools and nano WC-Co based reinforced composites. Therefore, the development of nano WC cemented carbide and the search for wider applications become the focus of development, and the key technology of preparation is the preparation of nano powder and the subsequent sintering process. Particle size is to improve the performance of WC-Co hard alloy (strength, hardness and wear resistance of the Jun effective way, therefore the development of nano cemented carbide is the development focus of the next phase of the study, it will greatly broaden the application field of WC-Co hard alloy, and thus lead to a variety of precision instruments, mold, tool and electronic communication technology rapid development.

Are there any German products called K44 which are imported into cemented carbide materials? I am machining hole, K44 is better than domestic material K30?

K44 never heard of it! All I know is K40.K40 is better than K30, but almost stiff.K40 is suitable for rough machining, and K30 is suitable for finish machining.It's better to process K40 holes in general.

What blade does the high carbide material use?

CBN diamond tools, the price is relatively high, high hardness with this basic file, but not the car more than 55 degrees of hardening, if necessary diamond tools contact me. Domestic imports.
