Regulation and flow control of non ferrous metal melts
Al2TiO5 and Si3N4
- excellent thermal shock and corrosion resistance
- very low wettability of non ferrous metal melts
- increased productivity
- reduction of machine down time
H.C. Starck produces Nozzles and Slide Valves for regulation, control and dosing of molten aluminum. These parts can be made from our high tech ceramics StarCeram® AT or StarCeram® N. Both materials are characterised by an excellent thermal shock and corrosion resistance as well as a very low wettability by non ferrous metal melts. Besides an extremely high mechanical strength, Silicon Nitride has very good thermal conductivity. In contrast, Aluminum Titanate shows excellent insulating properties.
