Tungsten Carbide Razor Blades for Corrugated Cardboard Slitting Machine

What is carbide?

Carbide consists of composite materials whose carbide elements are bound by a binding agent.

The carbide content lies between 85 and 88 %, with a grain size from 0.7 to 3,5 µm.

The basic structure of carbide consists of tungsten carbide (WC) and cobalt (Co), which create different

carbide grades depending on their exact composition. Tungsten carbide also forms the hard phase,

while cobalt serves as a binder in the overall structure.

Features and advantages

Our high tech tungsten carbide razor blades are used successfully in many corrugated cardboard production

plants worldwide. Selecting the optimum composition of tungsten and cobalt with optimal grain size, our

razor blades achieve longer life time in terms of additional million meters of corrugated cardboard cutting

in comparison to the average duration of blades made in Europe.

The cutting surfaces of razor blades are mirror polished to reduce the work friction, extending the lifetime

of the blade and reducing the noise level during cutting.

• Higher quality level.
• Competitive prices level.
• Maximum blade lifetime is 16 million meters.
• Higher mirror finish (Ra = 0,02 µm).
• Each blade is separately packed.
