Slitting Blade Material Comparison: HSS (High-Speed Steel) or Tungsten Carbide?

Selecting the right slitting blade material directly affects cutting quality, efficiency, and cost performance. Whether you're processing film, foil, paper, tape, or lithium battery separator materials, choosing the right blade is essential.

HSS is a tool steel alloy containing tungsten, molybdenum, chromium, etc., known for good toughness and high-temperature resistance, suitable for medium and low-speed cutting.

Tungsten Carbide is a composite of tungsten carbide particles and cobalt binder, offering ultra-high hardness and excellent wear resistance, ideal for high-speed, precision cutting.

Advantages of HSS Blades:

Good toughness and impact resistance

Easy to sharpen and maintain onsite

Cost-effective

Suitable for paper, plastic films, and general materials

Advantages of Tungsten Carbide Blades:

Ultra-high hardness 

Superior wear resistance with much longer life

High cutting quality, perfect for high-speed and hard materials

Ideal for aluminum foil, lithium battery separator, and specialty materials

How to Choose?

Choose HSS blades for budget-conscious applications with moderate cutting needs.

Opt for Tungsten Carbide blades for high life and precision, especially on high-speed lines.

Select based on your material, equipment, and production requirements.
