A bronze alloy for very high integrity components, DTD 498 is a solution annealed and precipitation hardened copper nickel silicon alloy.
A copper bronze alloy containing nickel and silicon, DTD 498 is a UK Ministry of Defence specification designed for aerospace applications, which can be strengthened by heat treatment. The material provides an attractive range of performance characteristics, including high mechanical strength and excellent thermal and electrical conductivity. With good fatigue strength and corrosion resistance, DTD 498 is similar to the requirements of BS 2B 25, NFL 14-701, MSRR 8501, DIN 17672-1 and EN CW112C. Improvements in strength and hardness are achievable with further cold working.
DTD 498 is readily machinable and offers wear, galling and spark resistance characteristics.
Commercial applications for this engineering material include:
