DIRECTIONS FOR SUGGESTED USE
Melting temperature: 900 °C
Casting temperature:
100 °C over its melting temperature to cast with centrifugal machines.
120 °C over its melting temperature to cast in vacuum machines with controlled atmosphere.
140 °C over its melting temperature to cast in outdoor cylinders with vacuum.
Cylinders temperature: from 550 °C to 650 °C depending on the machine and
objects dimensions
Cooling casted objects: in water after 10 minutes
Cooling casted objects (with stones): in water after 30/40 minutes
Annealing: 650 °C for 30 minutes followed by a quick cooling in hot
water (40° C min.), better if with alcohol.
