Cemented carbides are a class of hard materials used extensively for cutting tools, as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate.

Cemented carbide is a composite material prepared by powder metallurgical methods. It has the advantages of high hardness, good toughness, and wear and corrosion resistance due to the combination of hard phase and soft metal binder phase [1–3].

What is cemented carbide? Cemented carbides represent a group of materials which differ from other hard materials such as ceramics, corundum or diamond in view of their metallic properties. These metallic properties include for example good electrical and thermal conductivity.

2022年10月29日 · Cemented carbide is a powder metallurgy alloy composed of one or more refractory carbide powders and metal powders (cobalt, nickel, etc.) used as an adhesive. It is generally used in the production of high-speed cutting tools and tools for cutting hard and abrasive materials, as well as cold-working molds, measurement instruments, and impact ...

Introduction. Cemented carbide is known for its impressive hardness, strength, wear resistance, and corrosion resistance, making it a key material in various industries.Commonly referred to as the “industrial tooth,” it plays a critical role in many manufacturing processes. This composite material is made from hard metal carbides combined with a binder metal through powder …

2016年12月5日 · Cemented carbides are a range of composite materials which consist of hard carbide particles bonded together by a metallic binder. The proportion of carbide phase is generally between 70-97 % of the total weight of the composite and its grain size averages between 0.4 and 10 μm.

2024年1月12日 · Cemented carbide has high hardness, high abrasive resistance, high elasticity modulus, low coefficient of thermal expansion, and stable chemical properties. Cemented carbide products include cutting tool, mining tool, and wear parts, and they are widely used for mechanical working, mining, oil & gas exploitation, and infrastructure construction.

2019年1月1日 · In cemented carbides, these hard particles are mainly tungsten carbides (WC) compared to cermets (TiC, TaC, NiC) or ceramics where metal oxides or nitrites are used. Cemented carbide is one of the most successful composite engineered materials. Its unique combination of strength, hardness, and toughness satisfies the most demanding applications.

Cemented carbide (also known as solid carbide or tungsten carbide (WC)) is one of the most successful composite engineering materials ever produced. Its unique combination of strength, hardness, and toughness satisfies the most demanding applications.

2014年1月1日 · Approximately 50% of all carbide production is used for metal cutting applications. This article discusses the manufacture and composition of cemented carbides and their microstructure, classifications, physical and mechanical properties, and applications.
