Chemical Analysis of Tungsten Carbide Ball

Making spectrographic chemical analysis of Tungsten Carbide can be difficult and uncertain, so the accepted procedure is to use a magnetic permascopic evaluation. If anyone tells you that they can analyze tungsten carbide to an exact figure, ask them for the error budget on their process. If they know the uncertainty, it will be in percentage points.

The same exactness of chemistry and physical properties in tungsten carbide that are experienced with alloy metals cannot be expected, as T.C. is made from a physical mixture of a pure metal powder and a powdered ceramic. There will naturally be more variability in performance.

The stiffness or Young's modulus of elasticity given for Tungsten Carbide has been measured in tension, but balls are almost always used in compression. In our experience, the Young's modulus of elasticity of cemented tungsten carbide is actually 10% higher in compression than it is in tension.

The performance of tungsten carbide ball

Tungsten Carbide Balls good performance at temperatures up to 800 degree Fahrenheit ( 427 centigrade ) make it a good choice in high temperature applications.

Tungsten Carbide Balls has good corrosive resistance in many environments.

The material has a very low rate of thermal expansion, at 2 microinches per inch per degree Fahrenheit (4.9 X 10-4 per degree C). Steel is 6.4 and aluminum is 12 microinches per inch per degree Fahrenheit.

One of the very important features of this material is that it is electrically conductive, with a resistivity of two micro ohms per centimeter. This conductivity sets it apart from other hard stiff materials, such as ceramics and sapphire, because it allows it to be machined into complex forms by the Electrical Discharge Machining (EDM) process. Cemented Tungsten Carbide can be ground and lapped using diamond grit. The material is slightly magnetic. Small diameter balls can be picked up with a magnet. Cemented Tungsten Carbide is very heavy, with a density of .54 pounds per cubic inch or 15 grams per cubic centimeter.

Cemented Tungsten Carbide is neither a metal nor is it a ceramic. It is a cermetal although this isn't a widely used term. This is a combination of a large percentage of Tungsten Carbide ceramic particles bonded together by a small percentage of a metallic binder, to form a solid mass.

Physical Property of Tungsten Carbide Ball

Cemented Tungsten Carbide is an incredible material. It was originally developed for use as a cutting tool, in machine tools applications, where it still finds wide use today.
It is extremely hard at 91 HRA which is equivalent to 1500 Vickers 30. This material is very wear resistant, with some abrasion tests showing it at 30 times hard steel. It has good long-term dimensional stability, which makes a good material for gage applications.
Cemented Tungsten Carbide is extremely stiff, with a Young's modulus of elasticity of 98,000,000 pounds per square inch, compared with steel at 30,000,000 PSI. This high stiffness makes cemented tungsten carbide balls a good choice for ball-sizing and they provide premier results as components of kinematic couplings.

The Characteristic of Tungsten Carbide Nozzle

Tungsten carbide nozzle is made from hot pressing with straight bore and venturi bore type. Due to its hardness, low density and excellent wear and anti-corrosion, Tungsten carbide nozzle has been widely used in sandblasting and shot peening equipment, offering a long life with optimum air and abrasive use.

What is Tungsten Carbide Nozzle?

Tungsten carbide nozzle is a device designed to control the direction or characteristics of a flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe via an orifice. For nozzles, tungsten Carbide nozzle is the most rugged and durable and provides the best value.

Tungsten carbide bar

Tungsten carbide bar is widely known as one kind of carbide cutting tools, it’s available for different grinding geometric parameters and suitable for both cutting materials and nonmetal materials, also it can be applied to conventional, semi-automatic lathe, automatic lathe and planning machine to work grooves and operate cutting, etc.

Tungsten Carbide Mechanical Rings

Tungsten Carbide Seal Rings are used as Mechanical Seal faces in pumps, Compressors and Agitators. These are used in Oil Refineries, Petrochemical plants, Fertilizer Plants, and Drugs/Pharmaceutical Industries. Mechanical seal rings are developed to withstand high temperature, high pressure & highly corrosive chemical attack. We manufacture Rings in various shapes like Plain Ring, DA type, T-shape, L-shape and in shapes as per customers requirement. Tungsten Carbide Rings are generally made with Cobalt as binder material. Nickel bonded Rings also can be supplied. 

The Application of Tungsten Carbide Rods with Holes

Tungsten carbide rods with holes are suitable for the manufacturing of various kinds of solid cemented carbide tools for the machining of heat-resistant alloys and Ti alloy, also suitable for the manufacturing of micro drills used for machining PCB. Tungsten carbide rod with hole also plays a part in cooling process of machining.

Tungsten carbide road digging button bits

Tungsten carbide road digging button bits are used to mining the road. It can be used to reduce wear on rubbing surfaces found in roller cone drill bits, diamond bits, down-hole stabilizers, and numerous other applications.

The Superiority of Tungsten Carbide Sheet

Tungsten carbide sheet: assured quality, stable characters; experienced producing technology and advanced facilities.
After rolling and processing with deflection reaching 60%, the density of tungsten carbide sheet basically comes close to tungsten’s theory density. Therefore, tungsten carbide sheet possesses the properties of high density, balanced internal structure and excellent high creep strength temperature.

The Application of Tungsten Carbide Sheet

Tungsten carbide sheet is widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied in vacuum furnace, titanium sputtering target applied in plasma coating film, and high temperature resistance boats. 

Why Use Tungsten Carbide？

Tungsten carbide (WC) is an inorganic chemical compound containing equal parts of tungsten and carbon atoms. In its most basic form, it is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, tools,abrasives, as well as. Tungsten carbide is approximately three times stiffer than steel, and is much denser than steel or titanium. It is comparable with corundum in hardness and can only be polished and finished with abrasives of superior hardness such assilicon carbide, cubic boron nitride and.

The Common Drill Bit

Common home repair drill bits are made of steel or High Speed Steel (HSS). Although inexpensive, common steel drill bits tend to wear out or break very quickly. HSS drill bits last longer than steel, but are more expensive. These types of drill bits are most effective when used on wood, drywall or plastics.

The Application of Tungsten Carbide End Mill

Tungsten carbide end mill is used for milling, with one or more of the rotary tool cutter.The margin in workpiece is cut by the mill intermittently. Carbide end mill is mainly used in processing plane, steps, grooves, forming the workpiece surface and cutting and so on. There are two common materials for manufacturing end mill: high-speed steel, and tungsten carbide. Carbide end mill has relatively higher hardness, stronger cutting ability, and can improve the speed and feed rate as well as increasing productivity.

When to Use a Carbide Drill Bit

Tungsten carbide drill bits undergo a lot of stress when drilling a hole. The high-speed rotation of drill bits generates friction that, in turn, generates heat. The friction between drill bit and material leaves drill bits slightly duller after each use. The heating and cooling of the drill bit material can weaken the internal structure of the bit over time.

The development history of PCD drill

Tungsten carbide PCD drill was developed by PrecorpInc in Utah in American.The trade mark DiaEdge of PCD drill was owned by this company. Since 1980s,metal cutting began to be used,but it didn't establish credibility in the minds of people.Nowadays,the PCD drill processed by high temperature and high pressure sintering gets people's attention again and the scope of its application is also widely expanded.
