Tungsten Carbide Blades Overview

What Are Tungsten Carbide Blades

You might ask what makes lame in carburo di tungsteno different from other cutting tools. These blades are made with a special material called carburo di tungsteno. This material mixes carburo di tungsteno grains and a cobalt binder. The mix makes the blades very hard and tough. On the Mohs scale, carburo di tungsteno gets a 9. Only diamonds and a few other things are harder than that.

Lame in carburo di tungsteno do not wear out fast. They keep their sharp edge much longer than steel blades. You can use them for hard jobs where other blades break. These blades work well in high heat and with rough materials. They do not lose their shape or sharpness. If you test them, you may feel a small magnetic pull. They do not rust like iron-based steels. This makes them easy to spot. They are great for places with water or chemicals.

Mancia: If you want a blade that stays sharp and lasts long, lame in carburo di tungsteno are a good pick for woodworking, mining, aerospace, and many other jobs.

Tungsten Carbide Blade vs. Steel Blade

When you look at a tungsten carbide blade and a steel blade, you see big differences. The table below shows how they compare:

Lame in carburo di tungsteno stay sharp much longer than steel blades. You will not need to sharpen or replace them as often. They also make cleaner and more exact cuts. Steel blades cost less at first and can handle hard hits better. They bend more and do not break as easily. If you need a cheaper blade or work with lots of shocks, steel blades might be better. But for most jobs that need clean cuts, lame in carburo di tungsteno work best and last longer.

Nota: Lame in carburo di tungsteno may cost more at first, but they save you money in the long run because they last longer and cut better.

Material and Properties

Tungsten Carbide and Cobalt Composition

Typical Composition Ratios

Most industrial blades use a mix of tungsten carbide and cobalt. The cobalt amount is usually between 6% and 20% by weight. This range helps the blade stay hard, tough, and last longer. For example:

• YG6 grade blades have about 6% cobalt. These blades are very hard and resist wearing out, so they are good for cutting tools.
• YG15 grade blades have about 15% cobalt. These blades are tougher and can take more hits, which is important for heavy-duty tools.

The rest of the blade, between 70% and 97%, is tungsten carbide. If you want a blade that stays sharp longer, pick one with more tungsten carbide. If you need a blade that can handle more shock, choose one with more cobalt.

Role of Cobalt as a Binder

Cobalt works as a binder in these blades. It holds the tungsten carbide grains together. More cobalt makes the blade tougher and less likely to break. But the blade will be a bit softer. Less cobalt makes the blade harder but also more brittle. This means it can chip more easily if you use it for tough jobs. Most companies use between 6% and 15% cobalt to get the best mix of hardness and toughness. This balance helps the blade last longer in hard jobs like metalworking and mining.

Hardness and Abrasion Resistance

Hardness Comparison with High Carbon Steel

Tungsten carbide blades are known for being very hard. You can see this in the numbers. The Vickers hardness for tungsten carbide is between 1100 and 2600 HV, depending on the grade. High carbon steel usually has a Vickers hardness below 1000 HV. The table below shows how different grades compare:

You can also see a chart below:

Wear Resistance in Demanding Applications

Tungsten carbide blades have high hardness and wear resistance. This means they keep their edges sharp much longer than steel blades. In factories, these blades can last 300% to 500% longer than regular steel blades. Their special structure helps them resist bending and edge wear, even at high speeds or for long times. For example, in paper or textile factories, you can use a tungsten carbide blade for months before sharpening. This saves time and money on repairs. The fine grain size and the right amount of cobalt help the blade resist chipping and keep cutting well.

Mancia: If you want a blade that can cut tough, rough materials and keep its edge, pick one with high hardness and wear resistance.

Heat Resistance and Edge Retention

Performance at Elevated Temperatures

Tungsten carbide blades work well even at high temperatures. You can use them for cutting when it gets up to 900°C or even 1000°C. The blade keeps its hardness and does not lose its shape or sharpness. This makes it great for jobs that get very hot, like metal cutting or machining.

Edge Retention in Continuous Use

Edge retention is a big reason to pick lame in carburo di tungsteno. These blades can keep their edges sharp up to 10 times longer than most other knife materials. Even if you use them all the time, you will not need to sharpen them often. Some people use the same blade for months without sharpening. This high edge retention comes from the blade’s great hardness and wear resistance. But remember, these blades are more brittle than steel. They work best for straight cutting and slicing, not for prying or twisting. You need special diamond stones to sharpen them, but you will not need to do this often.

Nota: If you need a blade for lots of use and want to avoid sharpening, tungsten carbide blades give the best edge retention and long-lasting performance.

Manutenzione e cura

Sharpening and Handling

Recommended Sharpening Tools and Techniques

Per mantenere il tuo lame in carburo di tungsteno sharp, you need special tools. Diamond grinding wheels are the best choice. Diamond is harder than carburo di tungsteno. It sharpens the blade fast and keeps it accurate. Always use coolant to stop the blade from getting too hot. Silicon carbide grinding wheels are cheaper but wear out faster. Use them only for light sharpening jobs. Electrical Discharge Machining (EDM) is good for tricky blade shapes. It uses electric sparks to shape the blade without touching it. Laser sharpening uses a strong light beam to make blades sharp again. This works well in big factories with lots of blades.

Mancia: Always keep the blade cool when sharpening. This stops tiny cracks and keeps the edge strong.

Proper Sharpening Angles for Tungsten Carbide Blades

Try to match the sharpening angle to the original one. This keeps the blade’s shape and helps it last longer. If you use the wrong angle, the blade can chip or wear out quickly.

Safety Precautions During Sharpening

Wear gloves, goggles, and a dust mask. Dust from carburo di tungsteno can be bad for you. Use a dust collector to keep your work area safe.

Cleaning and Handling After Sharpening

After sharpening, clean the blade with a gentle cleaner. Dry it well before using it. Handle the blade carefully so you do not chip the edge.

Maximizing Blade Life

Routine Cleaning and Maintenance

Check your blades every week or after 20 hours of work. Look for dull spots, cracks, or rough edges. Clean with a soft cloth and gentle cleaner. Do not use strong chemicals.

Pratiche di conservazione adeguate

Keep blades in a dry, cool place. Use blade cases or racks to stop bending or damage. Keep the room less humid than 60% to stop rust.
