Introduction Of The Performance Of Tungsten Steel Blades(Cemented Carbide Blades)

Tungsten steel blades—more commonly known in industrial manufacturing as cemented carbide blades—represent the gold standard for high-performance cutting tools. Composed primarily of tungsten carbide particles bound together by a metallic binder (usually cobalt or nickel), these blades combine the extreme hardness of ceramic with the toughness of metal.

As a Tungsten Carbide Knife Manufacturer, we have summarized the performance of tungsten steel blades in the following aspects.

(1) High hardness. The hardness of tungsten steel can reach 8.9--9.1 Mohs hardness, the tungsten steel blade is 10 times that of 18K gold, and the iron gold is 4 times, which is equivalent to natural sapphire. The high hardness makes the tungsten steel very wear-resistant, and it is not easy to cause scratches, deformation and the like.

(2) High brightness. After the tungsten carbide blade is highly polished, the tungsten steel blade is fully embossed with jewel-like color and brilliance, and the brightness is like a mirror.

(3) Tungsten steel has good corrosion resistance. Through artificial sweat test, the cutting machine blade does not corrode completely. It does not fade. It does not change color, is not allergic. It does not rust, the gloss can be kept for a long time, and the use of tungsten steel blades is impossible for other metals.

(4) Tungsten steel has high density and strong texture, and is a fashionable jewelry material. The industry involved in tungsten steel blades: plastic particles, plastic recycling and so on. The types of Tungsten Carbide Cutter Blade can be divided into: pelletizer blades, crusher blades, tungsten steel blades and the like.

Performance Comparison: Carbide vs. High-Speed Steel (HSS)

Performance Metric	Tungsten Steel (Cemented Carbide)	High-Speed Steel (HSS)
Edge Retention	Extremely high; lasts 5x to 20x longer	Moderate; dulls relatively quickly
Cutting Speed	Can operate at high RPMs and feed rates	Limited to lower speeds to prevent overheating
Initial Cost	Higher upfront investment	Lower initial cost
Long-Term Value	High efficiency and less frequent replacements	Frequent sharpening and replacements required
Brittleness	More brittle; sensitive to shock/impact	Tougher; more forgiving under sudden impact
