Application
Designed for the filtration of aluminium and aluminium-alloy melts, effectively removing oxides, slag and non-metallic inclusions.
Aluminium filtration solution
Alumina Based Ceramic Foam Filters
Our alumina ceramic foam filters are manufactured using a precision replication process to create a uniform, open-pore structure. Their excellent chemical stability enables reliable filtration without reacting with molten aluminium.
The tortuous pore network captures oxides, slag and other non-metallic inclusions while regulating metal flow. This promotes cleaner, smoother castings and consistent performance at aluminium pouring temperatures.
Key advantages
- Improved surface finish
- Reduced porosity and inclusions
- Enhanced mechanical properties
- Stable performance at pouring temperatures
