HIDURAX 1 is a complex nickel-aluminium
bronze possessing good mechanical strength and hardness, and advantageous
ductility, corrosion resistance and wear resistance. The alloy’s
excellent properties are maintained at elevated temperatures and
it possesses very good resistance to oxidation. Also of benefit,
are HIDURAX 1’s superior bearing properties and fatigue strength.
