GLZ-Tuff - Advanced Wear Protection

In certain extreme and aggressive wear applications, conventional Alumina ceramics offer inadequate protection. GLZ-TUFF is a unique range of Zirconia enhanced Alumina ceramic products. These products are produced through a proprietary process allowing for excellent affordability while offering advanced wear protection.


GLZ-TUFF has high mechanical strength, excellent abrasion resistance and superior fracture toughness. Traditionally, Zirconia enhanced wear resistant products were only used in a limited number of high wear applications like pump components, valve seals and bushes due to the high cost. Groupline is now able to offer GLZ-TUFF at an affordable price making the use of these advanced Zirconia enhanced products feasible for use in larger installations such as pipes, chutes and mill linings.

GLZ-TUFF is available in the same standard tiles sizes used for traditional Alumina ceramics. We are also able to offer GLZ-TUFF pre-engineered tiles and products for unique applications.

GLZ-TUFF outperforms Standard Alumina Tiles by more than four times!

Application Examples:

  • Wear panels
  • Classifiers
  • Cyclone Separators
  • Pipe Linings
