Beryllium Copper is Widely
Used as a die metal for high –volume permanent mold
casting (some foundries use nickel beryllium for this purpose).
While beryllium copper is more expensive, off the shelf,
than steel or cast iron, its physical properties clearly
make it the cost effective choice when the volume of casting
production is high enough. The important factors involved
are copper beryllium’s high thermal conductivity,
elevated temperature ductility and its good machinability.
The high thermal conductivity - up to 10 times that of tool
steel – reduces susceptibility to thermal fatigue
and heat checking.

Casting Die
Beryllium Copper dies can
remain serviceable for 30,000 to 50,000 shots depending
on the alloy being cast and the shape, size and complexity
of the casting. After this initial service period, however,
beryllium copper dies are normally reworked once or twice.
Beryllium copper’s high machinability is important
here, since it significantly reduces the cost of die rework
compared with that for steel dies. The total life of a beryllium
copper die may therefore extend as much as 150,000 shots,
far more than other die materials.
