    The Zkr International alumina wear resistance pieces, are characteristic by their high mechanic properties, which give them and excellent performances in front of the wear. With a high resistance against any chemical attack and it high temperature resistance made that said kind of pieces are appropriate for using at all kind of industries.

    The alumina wear resistance pieces, from decades have been utilized as protection elements in all kind of equipments and installations, which suffer abrasions and wears. Our wear resistance pieces are designed to protect industrial installations such as: turbines, cyclones, pipes, bunkers,…which works in extreme abrasion conditions or corrosion at all industrial sectors.

     A good protection against abrasion and wear, gives an optimum efficiency at industrial equipments and installations, during a much longer period, avoiding unnecessary stop at the process, which improve the production costs.
