Ceralu® Al203 Filter
Ceralu® Al203 ceramic foam filters have been used successfully for more than three decades in Aluminium DC casting as well as continuous casting of Aluminium alloys. The filters have a very good chemical resistance and are suitable for all kinds of alloys, including those with high magnesium content and aerospace alloys. Drache manufactures these filters in all standard dimensions and porosities. Special dimensions and designs are, of course, available on request.
Drache offers three special types of Ceralu® filters: the Ceralu® HF filter and the Duplex filter, as well as a Ceralu® filter made of a modified material that is specifically optimised for use in Aluminium-lithium alloys.
