What is Carbide?
Cemented carbide is one of the commonly used alloy materials. Its biggest feature is its high hardness and wears resistance. In terms of composition, cemented carbide is based on one or more powders of refractory carbides, such as carbide, titanium carbide, etc., and metal powders such as cobalt and nickel are added as binders. An alloy made of metallurgy. Cemented carbide is commonly used in the manufacture of cutting tools, cold-work dies, and highly wear-resistant parts.
How is Carbide Made?
Firstly, a bond alloy is prepared by high-energy ball milling; then, the hard alloy is compounded according to the specified weight ratio of the cemented carbide composition, and then the hard alloy mixture obtained by the ball milling is vacuum sintered.
What are the characteristics of cemented carbide？
- First, cemented carbide has extremely high hardness and wear resistance. At room temperature, its hardness can reach 69 to 81 HRC, and the wear resistance is also quite good. Therefore, the cutting speed of tools made of this material can be 4 to 7 times faster than high-speed steel tools, and the service life will not be less than the latter, but 5 to 80 times longer than high-speed steel tools. High hardness material.
- Secondly, cemented carbide also has high strength and elastic modulus. Its compressive strength reaches 6000 MPa, and its elastic modulus can reach up to 735 MPa, both of which are higher than high-speed steel materials. However, the bending strength of cemented carbides is low, only 1000 to 3000 MPa.
- Third, cemented carbide has good corrosion resistance, oxidation resistance, and high-temperature resistance. Cemented carbide tools are generally resistant to corrosion caused by the atmosphere, acids, alkalis, etc., are not prone to oxidation, and can remain hard at high temperatures of 900 to 1000 degrees.
- Fourth, the linear expansion coefficient of the cemented carbide is small, which results in that it can have a stable shape and size during processing.
- Fifth, the products formed by using hard alloy processing can usually not be processed and reground. This is because the hardness and the brittleness of the gold are high, and it is easy to cause chipping when regrinding, so only electric machining such as an electric spark, wire cutting, electrolytic grinding or special grinding wheel grinding can be used.
Commonly Used Cemented Carbide Materials？
Commonly used cemented carbide materials are tungsten cobalt, tungsten titanium cobalt, and tungsten titanium tantalum. The main components of tungsten-cobalt cemented carbides are tungsten carbide and cobalt. The different grades are represented by the percentage of code YG plus cobalt content. The main components of tungsten-titanium-cobalt-based cemented carbides are tungsten carbide, titanium carbide, and cobalt. The grade is the percentage of YT plus titanium carbide content. Tungsten-titanium-tantalum-based cemented carbides are also called general-purpose cemented carbides or universal cemented carbides. Their main components are tungsten carbide, titanium carbide, tantalum carbide, niobium carbide, and cobalt. Grades are represented by YW plus ordinal numbers.
What Is Carbide Used For?
The most widely used field is as a tungsten carbide tool. Tungsten carbide materials can be used to make various types of carbide cutting inserts such as turning tools, milling cutters, planers, drills, woodworking tools, etc., which are suitable for different types of processing processes and workpiece materials. Among them, tungsten-cobalt-based hard alloys are suitable for short chip processing of ferrous and non-ferrous metals and non-metal materials; tungsten-titanium-cobalt-based hard alloys are more suitable for long chip processing of ferrous metals such as steel. In the same alloy, if the cobalt content is too large, it is more suitable for rough machining; the cobalt content is too small, and it is more suitable for finishing.
Cemented carbide is also widely used in cold-working molds such as wire drawing dies, cold stamping dies, cold extrusion dies, cold pier dies, and tungsten carbide rolls. Dies made of cemented carbide can better withstand impact and have better impact toughness, fracture toughness, fatigue strength, flexural strength and wear resistance. Generally, the cemented carbide used in the mold is selected from the medium, high cobalt, and medium and coarse grain grades. Generally, the carbide tool manufacturers use the YG symbol as the tungsten carbide grade.
In addition, cemented carbide is also commonly used in the manufacture of measuring tools and carbide wear parts, especially the wear-resistant parts such as inlays and parts on the easy-to-wear surfaces of measuring tools, precision bearings for grinding machines, guides, and rods for centerless grinding machines, and lathe tips.
What Is Carbide Steel?
Steel-bonded cemented carbide is a composite material produced by powder metallurgy with steel as the bonding phase and carbides (mainly titanium carbide and tungsten carbide) as the hard phase.
What Is Cermet?
Cermet is made of metal and ceramic raw materials. It has both the advantages of metal and the characteristics of ceramics. Due to its extremely high corrosion resistance, high toughness, high hardness, and high oxidation resistance, it is used in rockets and high-speed Highly respected in aircraft.
The metal raw materials most commonly used in the manufacture of cermets are iron, nickel, cobalt, etc. The most commonly used ceramic raw materials are oxides, silicides, borides, carbides and nitrides. The production of cermet is also relatively simple. The firing method is the same as that of ceramics, except that the metal powder material is mixed into the ceramic soil to produce different products according to requirements.
