PROPERTIES
Foam ceramic filters for max. casting temperatures up to 1450°C in various sizes, thicknesses and materials. The application of ceramic foam filters can be divided into the aluminium foundry sector and the iron, steel and heavy metal foundry sector. In our assortment you will find:
- KS ceramic foam filter AS (up to 820°C) for many aluminium casting alloys
- KS ceramic foam filter Al2O3 (up to 1000°C) for common aluminium castings and wrought alloys as well as pure aluminium
- KS ceramic foam filter SIC (up to 1450°C) for cast iron alloys, copper, bronze and brass alloys as well as aluminium alloys
- KS ceramic foam filter ZrO2 (up to 1700°C) for common steel alloys, cobalt and nickel-based alloys as well as iron and magnesium castings
