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
  • Excellent strength at high temperatures
  • Standard and custom sizes available
  • Various pore sizes
  • Improved metal quality
  • CFF Mould Filters
  • CFF Stalk Tube Filters
