What is Tungsten Carbide Tip

Tungsten carbide tip is made from tungsten carbide powde and cobalt or other binders, which owns the properties of high hardness, wear and abrasion resistance, cemented carbide is the ideal material for many cutting tools and mechanical parts.

Tungsten carbide tip as the common part of tungsten carbide tip, one tungsten carbide tip can replace 4 to 10 steel tips, its penetration rate twice as high, while the tungsten carbide drill tip replacement less often, improve production efficiency, perforation rate. Tooth tungsten carbide drill for, it is required to adapt to a variety of rock properties teeth, perforation rate, abrasion resistance, shock resistance, so as to achieve long service life. Tungsten carbide drill tip has become a major tool for high-efficiency perforated. Currently tungsten carbide tips for large and medium-sized open-air metal mines, especially for large open pit type non-ferrous metal perforation, tungsten carbide tip has broad prospects.

Tungsten carbide tip take on the important task of engineering geology, oil exploration, mining and civil construction. Tungsten carbide tip as traditional tips, tips by the complex role of impact and abrasion, harsh working conditions, there are at least wear mine rock form more than four, namely: thermal fatigue wear, shock wear the shock of fatigue wear and abrasive wear. Tungsten carbide tips compared with the general tips, have higher hardness, strength and toughness. Tungsten carbide able to adapt to changing conditions better,and under the guarantee toughness does not fall have further improve the wear resistance of the alloy.

Tungsten Carbide Indexable Inserts

Tungsten carbide indexable inserts are replaceable and usually indexable bits of cemented carbide used in machining steels, cast iron, high temperature alloys, and nonferrous materials. Tungsten carbide indexable inserts allow faster machining and leave better finishes on metal parts. Tungsten carbide indexable inserts can withstand higher temperatures than high speed steel tools.

Tungsten carbide indexable inserts are composed of a metal matrix composite where carbide particles act as the aggregate and a metallic binder serves as the matrix. The process of combining the carbide particles with the binder is referred to as sintering. During this process, the binder eventually will be entering the liquid stage and carbide grains remain in the solid stage. The binder is embedding/cementing the carbide grains and thereby creates the metal matrix composite with its distinct material properties. The naturally ductile metal binder serves to offset the characteristic brittle behavior of the carbide ceramic, thus raising its toughness and durability. Such parameters of carbide can be changed significantly within the carbide manufacturer's sphere of influence, primarily determined by grain size, cobalt content, dotation, and carbon content.

Tungsten carbide indexable inserts are more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide. Most modern face mills use carbide inserts, as well as many lathe tools and endmills.

Our products provide optimum performance for a broad range of operations, including contouring, facing, slotting, and ramping. Inserts feature a unique and highly developed combination of substrate and coating configurations that can handle any workpiece material in any machining environment. Dapra is a leading manufacturer of cutting tools for the automotive, die and mold, machining, medical and aerospace industries.

What is Tungsten Carbide Blank

Tungsten carbide blank is a kind of solid tungsten carbide. They are made of grains of tungsten and carbon held together in a matrix of metal such as cobalt or nickel. There are many different grades of tungsten carbide. Refer to our carbide and advanced material section for more articles on carbide.

Tungsten carbide blank material can be called a powdered metal because tungsten is a metal. It is also classified as a ceramic. Ceramics are often defined as a class of materials that are not anything else. It can actually make the most sense to think of tungsten carbide as a ceramic when you are using it and a powdered metal when you make it.

Tungsten and most metals arrange themselves in a lattice which is like a 3 D version of a chain link fence. Under great heat and pressure the carbon atoms are actually packed inside the tungsten atoms instead of being joined side by side as with ordinary compounds.

Tungsten carbide blanks are very common material on any sort of cutting tool: For example, saw blades, lathe bits, drill bits, router bits and dental drilling tips are generally made of carbide. Carbide is so popular in these sorts of tools because it stays sharper longer than most other materials. Additionally, some ball-point pens use carbide balls because it helps the pen last longer.

With something like a carbide blanks, the main body of the blade is made of steel. The small tips of carbide are brazed on to the body. A good carbide tip might hold an edge ten to twenty times longer than a tool steel tip.

Tungsten Carbide Flat Spray Nozzle

Tungsten carbide flat spray nozzle is made of high grade tungsten carbide, is one of the spray nozzles. In another way saying, tungsten carbide nozzles are usually used to sandblasting, therefore, users also call them tungsten carbide sandblasting nozzles. The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm. On machining tungsten carbide spray nozzle, we do the precision grinding and surface treatment to achieve Ra0.1 of the bore roughness and the Ra0.025 of the R place of both ends. There is a scientific curvature radius design in the both entrance. This design can ensure a smooth transit of the thread. Due to the overall materials processing, and no elevation in the bore, the phenomenon of easy-bending and plugging has been improved comparing with the ruby nozzle.

Tungsten carbide flat spray nozzle due to having good wear and thermal shock and corrosion-resistant overall performance, have high ratio in practical applications. Tungsten carbide flat spray nozzle is mainly used for catalytic cracking unit of refining equipment and some other that requires high temperature, corrosion, erosion occasions. With tungsten carbide flat spray nozzles, it make good to improve the bottomhole flow field, improve the ability of rock breaking, increase drill footage, and reducing drilling costs.

Tungsten Carbide Rotary Burrs

Tungsten carbide rotary burrs can be used to cut or polish a wide variety of materials encountered in dentistry. These include tooth material such as enamel, dentine and bone, dental materials such as amalgam, composite, glass-ionomer cements, polymer and ceramic veneers and precious and not-precious alloys. The bur pattern will be selected to cut a specific material in a specific application and the following table gives guidance on selection.cemented carbide dental burs

Safety in Tungsten Carbide Rotary Burrs Application

Eye protection must be worn to protect against ejected particles.
