Analyse Cemented Carbide Alloys in Cutting Tools

The cemented carbides most often employed industrially are made by sintering grains of tungsten carbide with a metallic binder, frequently cobalt. Tiny amounts of titanium, tantalum, chromium and/or vanadium carbides are also used; depending on the final composition, these additives significantly influence the material properties – and thus the performance – of the finished material.

CEMENTED CARBIDES – A SUCCESS STORY

content, the properties, such as hardness, toughness, strength, wear resistance, modulus of elasticity, etc. can be widely varied by means of the WC grain size. The finer the cemented carbide, the harder is the material, and contrariwise (Fig.7). In industry, the

All You Need to Know About Cemented Carbide

Cemented carbide is known to consist of carbide particles that are cemented into the composite with the help of a binder metal. Cemented carbides are mostly known to make use of WC or tungsten carbide, TiC (Titanium Carbide), or TaC (Tantalum Carbide) to serve as the aggregate.

What is cemented carbide? Factory Suppliers

What is cemented carbide? Cemented carbide is an alloy material made from a hard compound of a refractory metal and a binder metal by a powder metallurgy process. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, even at temperatures of

Effect of Fe content on the mechanical properties of a

Waste cemented carbide is processed via zinc melting to obtain WC, and the regenerated YG10 cemented carbide was prepared via low‐pressure sintering in this study. The effects of impurity element Fe on the microstructure and mechanical properties of a regenerated cemented carbide were studied via X‐ray diffraction, scanning electron microscopy, magnetic property tests, and mechanical

Sandrin Carbide

2019/11/18The properties of cemented tungsten carbide are greatly controlled by the amount of binder and the size of the carbide. The tungsten carbide itself is extremely high in hardness (which is why it's so good at machining other metals) but the cobalt is relatively soft.

Tungsten Carbide Uses Properties

Tungsten Carbide Physical Properties The microhardness of the carbide is 17300 MPa, the elastic modulus is 710GPa, the compressive strength is 56MP, and the coefficient of thermal expansion is 6.9 10-6 / K. Tungsten Carbide is a black hexagonal crystal with metallic luster and hardness similar to
