Pyropore Ceramic Foam Filters

Overview

Pyropore ceramic foam filters (CFFs) are high-quality filters used in molten aluminium, copper-based alloys and ferrous metals including grey, ductile and steel alloys. Pyropore CFFs are efficiently remove oxides and non-metallic particles. 

Pyrotek Offerings

Pyrotek's Pyropore ceramic foam filters are proven, high-quality filters which provide ultimate molten aluminium filtration. Constructed of high-strength ceramics, Pyropore provides a superior metal filtration. Ceramic foam filters are easily installed and provide an excellent solution for the removal of oxides. 

There are four different types of Pyropore ceramic foam filters:

• Partially stabilized zirconia (ZrO₂) ceramic filters
• Silicon carbide (SiC) filters
• Aluminium oxide (Al₂O₃) filters
• Aluminium oxide with graphite

Ceramic foam filters can be used in many processes, including: 

• Sand casting
• Investment casting
• Shell casting
• Low-pressure casting
• Permanent mould casting
• Holding and transfer systems
