Q: MIG and TIG welding of cobalt base carbide and medium low carbon steel, respectively, using copper wire and stainless steel wire. What kind of corrosive liquid should be used in the welding seam to be metallographic?MIG+ copper welding wire, MIG+ stainless steel wire, TIG+ stainless steel wire: According to the usage, the cobalt based alloy can be divided into cobalt base alloy wear, high temperature resistant cobalt and cobalt base alloy abrasion and corrosion of the alloy in aqueous solution. The general condition is both wear resistant or wear resistant and corrosion resistant performance, some conditions may also require high temperature wear resistance and corrosion resistance, and more in this complex condition, the more it can reflect the advantage of cobalt base alloy.

Q: Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?: Now on the market scrap carbide blade about 100 yuan / kg, depending on the alloy composition, trading area and fixed.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.

Q: What brand of carbide is used in woodworking tools?: Cemented carbide YG8/ has good toughness and good wear resistance. It is mainly used in drawing dies for wire and rod processing. At the same time, it is also suitable for rough cast, non-ferrous metal and its alloy, non ferrous metal, uneven surface and intermittent cutting, rough car, fine plane, fine milling, general hole and deep hole drilling, reaming and making woodworking tools, etc..

Q: What is the hardness of cemented carbide?: Different grades, different hardness, usually (86 ~ 93HRA, equivalent to 69 ~ 81HRC);

Q: What materials are ZK20 cemented carbides processed?: ZK20 belongs to the K hard alloy blades can car many materials, such as: wrought iron steel low alloy cast iron high alloy cast iron ductile cast iron Aluminum Alloy hard plastic

Q: What kind of cemented carbide is used for processing HRC40 degrees stainless steel?: It is recommended to choose YS8 welding tool. Very good processing quality can be obtained.

Q: What are the common kinds of cemented carbides?: Cemented carbide is a hard particle of refractory metals (tungsten, tantalum, titanium, molybdenum, etc.) that is mixed with one or more iron elements (cobalt, nickel, or iron), pressed and molded, and then sintered. Types and properties of cemented carbides: (1) classification and grade of cemented carbides. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide (WC) and binder cobalt (Co). The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt. For example, YG8 is a tungsten cobalt carbide that represents an average WCo = 8% and the remainder is tungsten carbide. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide, titanium carbide (TiC) and cobalt. The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide. For example, YT15 represents an average WTi = 15%, while the others are tungsten titanium cobalt carbide with tungsten carbide and cobalt content. The tungsten titanium tantalum (NB) hard alloy is the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.

Q: What are the carbide inserts on the turning tool welded to the handle?: Burn copper on the knife rest.Pour the borax onto it.Put the alloy blade on it.Borax fell on the alloy blade top with flame cutting money.Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly and cools naturally.

Q: The difference between cemented carbide and tungsten.: Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.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.Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.

Q: What are hard alloys? Which ones are they? How often are they chosen?: It is based on one or several carbides (TiC and WC) as the hardening phase, with carbon steel or alloy steel (such as high-speed steel, chrome molybdenum steel) powder as binder, powder metallurgy materials through proportioning, mixing, pressing and sintering. After annealing, it can be machined. After quenching and tempering, it has the same hardness and high wear resistance as the hard alloy. It can also be forged and welded, and has the characteristics of heat resistance, corrosion resistance and oxidation resistance. The utility model is suitable for manufacturing various tools with complicated shapes, such as twist drills, milling cutters, etc., and can also manufacture moulds and wear-resistant parts which work at higher temperature.
