Description

COLSPEED 90 is derived using the basis of a 10/5/5 aluminium bronze with an addition of finely dispersed lead particles with very good self-lubricating and anti-friction properties that improve performance in wear applications. It shows the following features and properties:


  • Very high strength
  • Excellent general corrosion resistance
  • Very high wear and galling resistance
  • Excellent machinability
  • Outstanding bearing properties
  • Spark resistance
  • Retention of properties at cryogenic temperatures
  • Equivalent Materials
