Nitrided Ferro Chrome, LC FeCr

Q: YW1 what do you mean by "YW" in carbide cutter head?: You can go to Zhuzhou tungsten alloy online to see them, there seems to explain in detail

Q: Carbide according to the structure of the words, what can be divided into?: Hard alloy is by grade, can be made into all kinds of special-shaped parts

Q: The use of cemented carbides YG and YT: Two, titanium is a rare metal, characterized by light weight, high strength and good corrosion resistance. Because of its stable chemical properties, good resistance to high temperature, low temperature, strong acid, alkali resistance, as well as high strength and low density, has been praised as "space metal"". YT alloy and YW alloy have better properties than YG because they contain titanium.

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: In addition to diamonds, Hunan there are no good carbide manufacturers? Product advantages in the ordinary blade, knife head and mining tools. Which factory's alloy is of good quality? The best size, with the original tungsten powder. Please know what to say, first thank you: Zhuzhou diamond that is the best, most of the rest is a relatively large number of private enterprises, also there are several points to Zhuzhou, Jingcheng, Seiko, meiteyou, delta force and so on are OK, probably a year there are hundreds of tons of production

Q: Carbide drills and cobalt high speed steel bit, which is good? What's the difference between these two materials?: This is the first use, each one has its own merits, hard alloy with high hardness, suitable for high speed drilling and high hardness materials, and high cobalt high speed steel has good toughness, suitable for low hardness material, suitable for drilling slower machine.

Q: Hard alloy die mold grinding angle how slim: The diamond electric grinding head can be polished, and the electric grinding head has a conical grinding head.

Q: How can I buy carbide die on the Internet? Who can help?!: Go out and look for it. Someone will want to surf the Internet at home.

Q: How hard metal is welded with stainless steel?: Braze welding can be used.Carbide containing tungsten, vanadium and other metals, melting point higher than stainless steel, can be consideredOxyacetylene brazing, using copper wire dipped in copper flux, brazing carbide and stainless steel.

Q: Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!: Hard alloy is too high and can not be polished by ordinary metallographic sand paper. It should be put on the machine tool by diamond grinding wheel, and the cost is also very cheapReally manual grinding, then you can add grinding cream to try, but the efficiency is very low
