Magnesium Oxide Foam Filter Description
The Magnesium Oxide Foam Filter is a three-dimensional reticulated porous ceramic filter fabricated from high-purity magnesium oxide (MgO) via specialized processes, typically appearing white or light grey-white in color; leveraging the extremely high melting point (over 2800°C) and superior chemical inertness of magnesium oxide, it operates reliably in extreme temperatures exceeding 1700°C, designed specifically for filtering metal melts such as aluminum, copper, magnesium, and steel, effectively capturing and removing non-metallic inclusions, oxides, and gas bubbles from the molten metal, thereby significantly enhancing melt purity, improving casting microstructure, reducing defects, and boosting the mechanical properties and reliability of final products, making it an indispensable key functional filtration material in modern high-end precision foundry, aerospace, and automotive industries.
Magnesium Oxide Foam Filter Features
- High Refractoriness: Magnesium oxide base withstands temperatures exceeding 1700°C.
- 3D Reticulated Structure: Open-cell porous design enables efficient depth filtration.
- Chemical Inertness: Non-reactive with most metal melts, preventing secondary contamination.
- Excellent Thermal Shock Resistance: Withstands rapid temperature changes during metal pouring.
- Effective Inclusion Removal: Captures micron-sized inclusions and bubbles, enhancing metal purity.
- Moderate Mechanical Strength: Sufficient strength to endure melt flow while allowing easy removal after use.

FAQ
What is a Magnesium Oxide Foam Filter?
It is a porous ceramic filter made from high-purity magnesium oxide, used to remove impurities from high-temperature metal melts and improve casting quality.
What are its advantages?
Common sizes range from 10 to 30 PPI (pores per inch), selectable based on metal purity and flow rate requirements.
How does it differ from regular ceramic filters?
It has higher temperature resistance and better resistance to alkaline melt corrosion, making it suitable for more demanding smelting conditions.
What should be noted during installation?
Ensure tight fitting between the filter and the pouring cup/runner to prevent bypass flow, and preheat to reduce thermal shock.
Is it suitable for vacuum or low-pressure casting?
Yes, its high strength and temperature resistance make it suitable for vacuum casting, low-pressure casting, and other processes.
