DIRECTIONS FOR SUGGESTED USE

Melting temperature: 950 °C

Melting temperature (after silver addition): 920 °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 600 °C to 700 °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: 680 °C for 20 minutes followed by a quick cooling in hot

water (40 °C min.), better if with alcohol.
