COLSPEED 90 is derived using the basis of a 10/5/5 aluminium bronze with an addition of finely dispersed lead particles. This composition gives a material that offers high strength, very good corrosion resistance and very high wear and galling resistance, combined with self-lubricating and anti-friction properties that improve performance in wear applications.
