Extreme conditions require special materials. Traditional materials simply
cannot cope with aggressive molten metals, maximum temperatures of 1000 °C and,
at the same time, temperature differences of several hundred degrees.
The ceramic material Aluminium Titanate (ATI) cannot be harmed under these
conditions. ALUTIT, the aluminium titanate produced by CeramTec, contributes to
ensure process management and to maximise productivity.
ALUTIT is not wetted by liquid aluminium. It is also well known for its
excellent thermal-shock resistance. Therefore it is very useful in aluminium
foundries. Its low thermal conductivity helps to save energy and due to its
good chemical and abrasive resistance, it guarantees molten masses with a
high degree of purity.
CeramTec produces primarily Riser Tubes/Stalk Tubes for low pressure die
casting and tubes for dosing furnaces, so called Dosage Tubes.
Further applications where Aluminium Titanate has proven to be suited are:
- Nozzles/Bushes as an insert or as a joint to the mould
- Spouts, Nozzles, Stoppers/Plugs and Sliding Plates for the flow control of molten masses
- Breakrings for the extrusion of brass
CeramTec also produces special parts upon customers’ requests, like
Spacers, Crucibles, Moulds, Casting Tips or Portliners.
