Q:Material properties of Cemented Carbides
Metal carbides, especially B, B, IV V VI B metal carbide melting point is above 3273K, the TAC hafnium carbide, respectively 4160K and 4150K, is the highest point currently know material. Most of the carbide hardness large, their microhardness is higher than 1800kg mm2 (micro hardness is hardness says one way for hard alloy and hard compound, microhardness 1800kg mm2 is equivalent to a diamond a Mohs hardness of 9). Many carbides are difficult to break down at high temperatures, and their antioxidant power is stronger than their constituent metals. Titanium carbide has the best thermal stability in all carbides, and is a very important metal type carbide. However, in an oxidizing atmosphere, all carbides are readily oxidized at high temperatures, which can be said to be a major weakness of carbides. In addition to carbon atoms, nitrogen atoms and boron atoms can also enter the voids of the metal lattices and form interstitial solid solutions. They are similar to the gap carbide in that they can conduct electricity, heat conduction, high melting point, high hardness and great brittleness at the same time. The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is a bonding metal. Is the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 DEG C.
Q:What are the three types of commonly used cemented carbides?
ISO divides cemented carbide into 3 classes: P, K and M.P class (equivalent to China's YT class) carbide by WC, TiC, and Co composition, also known as tungsten titanium cobalt carbide. This kind of alloy is mainly used for processing steel materials.
Q:The difference between carbide knife and white steel knife
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:High end markets for cemented carbides
In 2007, 16 thousand and 500 tons of cemented carbide produced in our country, 4500 tons were used in cutting tool production, and the quantity was quite similar to that in japan. But the value of the tool is only 800 million U. S. dollars, far less than Japan's 2 billion 500 million U. S. dollars, which fully shows that the overall production level of domestic carbide efficient tool is still quite a gap with foreign countries. Therefore, in the domestic enterprises can not meet the market demand under the premise of the manufacturing industry will have to rely on a large number of imports to solve. Data show that the main foreign market in China's high-end cutter sales growth rate of 30%, has exceeded the average annual growth rate of domestic knives.
Q:Is carbide resistant to alkali?
Hard alloy chemical composition are general acid-base stability, it has no effect on, also has strong alkali resistant corrosion resistant hard alloy sintered hard alloy is added in different metal powders, can improve the hard alloy for corrosion resistance
Q:Where can I buy more than 94 hardness carbide cutter head, welding, the best address in detail, thank you!
It's no problem to weld cemented carbide. Please call me when you need it
Q:Can ceramic tools process cemented carbides?
Specific to the needs of carbide processing brand to determine,Cemented carbide, such as tungsten carbide, can be machined with a CBN toolReference: "CBN tools for processing hard alloy material, Valin super hard"
Q:What is a hard alloy mixture?
Tungsten carbide mainly consists of tungsten carbide + other small elements,
Q:What kind of etching solution should be used for metallographic observation of MIG and TIG welding of cobalt based carbide and medium low carbon steel? Ten
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:What is the base material of carbide saw blade?
You can go to Zhuzhou tungsten alloy technology forum to see, detailed description of the carbide saw blade related knowledge, you can go to a lot of professionals with whom to communicate inside.
