Tungsten Carbide Hammer

Tungsten carbide hammer is composite by tungsten carbide and steel, in order to reduce the costs, the working parts is tungsten carbide, and this part is just a little part.
Chinatungsten Online are the professional manufacturer and supplier of tungsten carbide hammers, we are able to provide kinds of tungsten carbide hammers.

Tungsten carbide hammer owns the properties of a narrow range of concentrations of mixtures of carbon and iron that make steel, a number of different metallurgical structures, with very different properties can form. Understanding such properties is essential to making quality steel. At room temperature, the most stable form of pure iron is the body-centered cubic (BCC) structure called ferrite or α-iron. It is a fairly soft metal that can dissolve only a small concentration of carbon, no more than 0.005% at 0 °C (32 °F) and 0.021 wt% at 723 °C (1,333 °F). At 910 °C pure iron transforms into a face-centered cubic (FCC) structure, called austenite or γ-iron. The FCC structure of austenite can dissolve considerably more carbon, as much as 2.1% (38 times that of ferrite) carbon at 1,148 °C (2,098 °F), which reflects the upper carbon content of steel, beyond which is cast iron.

What is Tungsten Carbide Inserts

Tungsten carbide inserts is made from tungsten carbide powder and other binders, thanks to high precision and high reliability, tungsten carbide inserts have been widely used worldwide for improving productivity.

Tungsten carbide is 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. In recent decades, though, solid-carbide endmills have also become more commonly used, wherever the application's characteristics make the pros outweigh the cons.

Mining and tunneling cutting tools are most often fitted with cemented carbide tips, the so-called "Button Bits". Only man-made diamond can replace the cemented carbide buttons when conditions are ideal, but as rock drilling is a tough job the cemented carbide button bits remain the most used type throughout the world.

What is Tungsten Carbide Tips

Tungsten carbide tips 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 tips as the common part of tungsten carbide tips, 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 tips has broad prospects.

Tungsten carbide tips take on the important task of engineering geology, oil exploration, mining and civil construction. Tungsten carbide tips 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.
