Tungsten Carbide Blades Overview
What Are Tungsten Carbide Blades
You might ask what makes شفرات كربيد التنغستن different from other cutting tools. These blades are made with a special material called كربيد التنغستن. This material mixes كربيد التنغستن grains and a cobalt binder. The mix makes the blades very hard and tough. On the Mohs scale, كربيد التنغستن gets a 9. Only diamonds and a few other things are harder than that.
شفرات كربيد التنغستن 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.
نصيحة: If you want a blade that stays sharp and lasts long, شفرات كربيد التنغستن 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:

---|---|---|
صلابة | Extremely hard; ranks very high on Mohs scale | Less hard; dulls faster under heavy use |
ارتداء المقاومة | Maintains sharp edge much longer; lasts up to 100x longer | Wears down quickly; requires frequent sharpening |
كفاءة القطع | Higher due to sustained sharpness and precision | Lower due to faster edge dulling |
Impact Resistance | More brittle; less impact-resistant | More ductile; better at absorbing shocks |
طول العمر | Significantly longer lifespan in abrasive conditions | Shorter lifespan; frequent replacements needed |
يكلف | Higher upfront cost but better long-term value | Lower initial cost but higher maintenance costs |
التطبيقات المثالية | Precision cutting, industrial use, metalworking, packaging | High-impact or shock-loading scenarios |
شفرات كربيد التنغستن 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, شفرات كربيد التنغستن work best and last longer.
ملحوظة: شفرات كربيد التنغستن 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:
Material/Grade | Rockwell Hardness (HRA/HRC) | Vickers Hardness (HV) |
---|---|---|
YG6 (Tungsten Carbide) | 90.5 HRA | 1450 |
YG15 (Tungsten Carbide) | 86.0 HRA | 1100 |
G10 (Tungsten Carbide) | 93.0 HRA | 1650 |
الفولاذ عالي الكربون | 60 HRC (approx.) | <1000 |

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.
نصيحة: 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 شفرات كربيد التنغستن. 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.
ملحوظة: 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.
