What is Tungsten Carbide?

Solid Tungsten Carbide & Tungsten Carbide tipped tools are in daily use throughout the world today, from industrial plants to individuals on building sites. First & foremost its meaning is derived from the Swedish words tung sten, which mean “heavy stone.” In German, it’s referred to as Hard Metal (Hart Metall or HM) & for good reason because of it’s very heavy density ( roughly twice) compared to ordinary steel. Cemented carbide is a hard material used extensively in industrial cutting [...]

Why is tungsten carbide an ideal tool material?

Tungsten carbide is the most widely used type of high-speed machining (HSM) tool material produced by powder metallurgy, consisting of hard carbide (usually tungsten carbide WC) particles and a softer metal bond. composition. At present, there are hundreds of WC-based tungsten carbides with different compositions, most of which use cobalt (Co) as a binder. Nickel (Ni) and chromium (Cr) are also commonly used binder elements, and other additives can be added. Some alloying elements. Why are there so many carbide [...]

What is the classification method for tungsten carbide grades?

  The combination of different types of tungsten carbide powder, mixture composition and metal binder content, type and amount of grain growth inhibitors, etc., constitutes a variety of carbide grades. These parameters will determine the microstructure and properties of the tungsten carbide. Certain specific performance combinations have become the first choice for specific processing applications, making it possible to classify multiple carbide grades.     The two most commonly used carbide machining classification systems for machining purposes are the C grade system [...]

What is the manufacturing method of tungsten carbide workpieces?

What is the manufacturing method of tungsten carbide workpieces?    Carbide workpieces can be formed by a variety of processes. Depending on the size of the workpiece, the level of shape complexity, and the production lot size, most cutting inserts are molded using a top and bottom pressure rigid mold. In order to maintain the consistency of the weight and size of the workpiece at each press, it is necessary to ensure that the amount of powder (mass and volume) flowing [...]

What is the milling process for tungsten carbide?

What is the milling process for tungsten carbide?     The tungsten carbide powder is obtained by carburizing the tungsten (W) powder. The properties of the tungsten carbide powder, especially its particle size, depend primarily on the particle size of the raw tungsten powder and the temperature and time of carburization. Chemical control is also critical, and the carbon content must be kept constant (close to the theoretical ratio of 6.13% by weight). In order to control the particle size by a [...]

How to prepare the workpiece coating of tungsten carbide?

How to prepare the workpiece coating of tungsten carbide?     In many cases, the finished part needs to be coated. The coating provides lubricity and increased hardness, and provides a diffusion barrier to the substrate that prevents oxidation when exposed to high temperatures. The tungsten carbide matrix is critical to the performance of the coating. In addition to the main characteristics of the custom matrix powder, the surface properties of the substrate can be tailored by chemical selection and modification of [...]

The Benefits of Titanium Aluminum Nitride (TiAIN) For Your Tools

The Benefits of Titanium Aluminum Nitride (TiAIN) For Your ToolsWhen trying to get the most use out of your tools, you may want to add a specialized coating that will both protect and strengthen the material. There are a few options available, but one of the best is TiAIN. Today we want to look at how this process works and what makes it beneficial for your work. Titanium Aluminum Nitride (TiAIN) is a thin coating that was initially developed by [...]

The Benefits of Alumnium Chromium Nitride (AlCRN) for Coating Your Tools

The Benefits of Alumnium Chromium Nitride (AlCRN) for Coating Your ToolsIf you own a machine shop or work with similar tools, chances are you probably already have your devices coated with some protective layer. However, as technology progresses, it’s only natural for new discoveries to take what was once state-of-the-art and render it obsolete. This is true for machine coatings as well — and perhaps no substance demonstrates that better than Aluminum Chromium Nitride. Don’t let the name fool you. [...]

Advantages of Using Carbide Cutting Tools

Advantages of Using Carbide Cutting Tools   Cost-Effective Initially, the cost of switching over to these tools can seem expensive and unnecessary. However, over time you will wind up saving a lot of money, which is why they are such an excellent investment. But why are carbide cutting tools better than HSS? It comes down to heat and general wear and tear. Carbide (either tungsten or titanium) is much better at dissipating heat than steel. Thus, when using these tools, you don’t have to [...]
