- Aluminum Titanate: Al2TiO5
- excellent thermal shock and corrosion resistance
- low wettability with non-ferrous molten metals
- low thermal conductivity
Sprue bushings made from StarCeram® AT have very low wettability by molten aluminum, good chemical resistance and a very low thermal expansion. Therefore these kind of nozzles are very resistant to thermal cycling of several hundred degrees. The nozzles have excellent insulating properties which is highly advantageous in the area of the gate system.
