Hard Metal:
Hard metal refers to a category of materials that exhibit exceptional hardness, strength, and resistance to wear, typically being composed of high concentrations of carbides. It is commonly referred to as a cemented carbide due to its chemical composition involving a metal binder, usually cobalt or nickel, combined with a carbide phase such as tungsten carbide.
The hardness of hard metals is attributed to the presence of the carbide phase, which provides high abrasion resistance and strength while the metal binder assists in maintaining its integrity. The production of hard metal involves a sintering process, where powdered tungsten carbide and metallic binder are compressed and heated to high temperatures, causing the particles to bond together and form a solid and extremely hard material.
Hard metals are widely used in various industries due to their exceptional hardness and wear resistance properties. They find applications in cutting tools, machining applications, wear parts, mining tools, and drilling equipment, among others. The high hardness of hard metal allows it to withstand extreme heat, pressure, and mechanical stresses, providing longer tool life and enhanced performance over conventional tool materials.
In summary, hard metal is a category of materials with outstanding hardness and strength, consisting of a metal binder mixed with a carbide phase. Its exceptional properties make it highly sought after in numerous industries where durability and wear resistance are crucial factors for the optimal performance of tools and equipment.

Etymology of HARD METAL
The term "hard metal" has its etymological origins in the combination of two separate words: "hard" and "metal".
- "Hard" comes from the Old English word "heard", which means "having a solid or firm texture; not easily penetrated or broken". Over time, "heard" evolved into "hard" in Middle English, maintaining its original meaning.
- "Metal" derives from the Latin word "metallum", which refers to "any mineral or substance obtained from the earth". It entered Old English as "metel" and later transformed into "metal" in Middle English.
When these two words are combined, "hard metal" refers to a particular type of metal that possesses hardness and a solid texture. It is worth noting that "hard metal" is a broader term, and the specific properties of the metal can vary depending on the context.
