White Bronze ALZEN 305 / ALZEN 501

ALZEN 305 and ALZEN 501 are ZnAlCu-alloys with excellent antifriction qualities which have been developed by voestalpine Linz/Austria.

Advantages of ALZEN over BRONZE and other bearing alloys

  • Lower specific weight, hence substantial price advantage and lower freight charges
  • Reduced machining times through higher cutting speeds
  • Better anti-frictional and emergency running properties (no seizing of shafts 
  • Better embedding properties
  • More readily wetted by lubricants
  • Higher thermal conductivity
  • Higher internal damping factor. Therefore quiet running
  • Lower coefficient of friction. This largely eliminates the "stic-slip-effect" which is particularly advantageous when used in machine tool bearings
  • Longer life in many applications
  • Stable price which is not influenced by the wide fluctuations of the copper and tin market
