Hardness Overview

What is Hardness

Hardness shows how well something resists scratches or dents. When you use metals or ceramics, you want to know if they are tough. Carbide tools stay sharp longer than steel ones. Carbide is special because it does not wear out fast. People measure hardness to see what lasts in rough places. This helps you choose the best tool.

Hardness Scales

There are different ways to test hardness. The Mohs scale puts minerals in order from soft to hard. Diamond is the hardest, and carbide is almost as hard. The Vickers and Rockwell scales use machines to press into the material. They check how deep the point goes. These tests give numbers to compare things. Here is a table with some common hardness tests:

Factories test carbide with these scales. This makes sure tools and parts are good enough.

Why Hardness Matters

Hardness is important if you want tools to last. Carbide is good for cutting and shaping because it wears out less. Harder materials like carbide do not need to be replaced often. This saves time and money in factories. Using carbide makes products better and stops delays. It also keeps equipment safe and working well. Hardness helps you pick the right tool.

Hardness Comparison

Tungsten Carbide vs Diamond

You often see diamond listed as the hardest material in the world. Diamond scores a perfect 10 on the Mohs scale and reaches up to 10,000 on the Vickers hardness scale. You can use diamond to cut almost anything, even other hard materials. Diamond resists scratches, warping, and breakage. This makes it valuable for cutting, grinding, and drilling.

Tungsten carbide comes close to diamond in hardness. On the Mohs scale, carbide scores between 9.0 and 9.5. On the Vickers scale, carbide reaches 2,404 to 2,586. You find carbide in tools and dies because it stays sharp and strong. Carbide resists wear and lasts longer than steel. You can use carbide for shaping metals and making parts that need to survive tough conditions.

Tip: If you want a tool that lasts and resists wear, carbide is a smart choice. Diamond is harder, but carbide costs less and works well for most jobs.

Both diamond and carbide show strong durability. You see similar wear patterns in tests. The first phase of wear often removes the softer matrix around the hard particles. Both materials resist scratches and keep their shape under pressure. You choose diamond for extreme hardness, but carbide gives you a balance of strength and cost.

Other High Hardness Materials

You can find other materials with high hardness for industrial use. Each material has its own strengths and weaknesses. Here are some common options:

• Ceramics (Alumina): Alumina ceramics score 8 to 9 on the Mohs scale. On the Vickers scale, they reach 1,504 to 2,000. You use ceramics for cutting tools, electrical insulators, and wear-resistant parts. Ceramics resist heat and corrosion, but they can break if hit hard.

• Tool Steels: Tool steels range from 7 to 8 on the Mohs scale. Their Vickers hardness goes from 580 to 2,000. You use tool steels for making dies, molds, and cutting edges. Tool steels are tough and resist bending, but they wear out faster than carbide.

• Boron Carbide: Boron carbide is one of the hardest materials after diamond and carbide. It scores 9.5 to 9.75 on the Mohs scale. You find boron carbide in armor, abrasives, and cutting tools. Boron carbide resists wear and keeps its shape, but it can be brittle.

You see that diamond, carbide, ceramics, tool steels, and boron carbide all resist wear and scratches. Diamond and carbide stand out for their extreme hardness and durability. Ceramics and boron carbide offer good resistance, but they may break under heavy force. Tool steels give you toughness, but they do not last as long as carbide.

Note: When you choose a material for a Carbide Die or Tungsten Carbide Die, you need to think about hardness, cost, and toughness. Carbide gives you a good mix of these qualities.
