Melting temperature: 880° C
Casting temperature:
100° C over its melting temperature to cast with centrifugal machines.
140° C over its melting temperature to cast in outdoor cylinders with vacuum.
120° C over its melting temperature to cast in vacuum machines with controlled atmosphere.
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: 620° C for 20 minutes followed by a quick cooling in hot
water (40° C min.)
