Ceramic Foam Filter

Ceramic Foam Filter

Alumina Ceramic Foam Filter

Alumina Ceramic Foam Filter is mainly used for the filtration of molten aluminium and alloys in foundries and cast houses. With the excellent resistance to attack and corrosion from molten aluminum, the alumina foam filters can effectively remove inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to the bottom-line profit.

Cangchen is a recognized leader in the development and production of casting filters both at home and abroad, with excellent innovation capability in filter manufacturing technology. We not only customize foundry filtration products for customers with their own brands but also customize alumina ceramic foam filter solutions and services for them.


Alumina Ceramic Foam Filter is a high-performance filter that is designed for use in the metal casting industry. The filter is made from high-quality alumina ceramic material that provides excellent filtration properties and durability.

Alumina ceramic foam filters are mainly used in the purification process production of non-ferrous alloys such as aluminum and aluminum alloys, and can also be used as gas-solid, liquid-solid separation medium, catalyst substrate, ceramic burner, sound absorption, environmental protection, and other fields.

Ceramic foam filter plays a vital role in removing these impurities and preserving high-quality castings.

Key Features and Benefits of Alumina Foam Filters:

The Alumina Ceramic Foam Filter offers several key features and benefits that make it an ideal choice for metal casting applications. These include:

1. High Filtration Efficiency:

The filter has a porous structure that ensures high filtration efficiency. It effectively removes impurities, such as slag, dross, and non-metallic inclusions, from molten metal, resulting in higher-quality castings.

2. Improved Metal Quality:

The use of our ceramic foam filter can improve the mechanical properties of castings, such as tensile strength, elongation, and impact strength, as well as the surface finish.

3. High-Temperature Resistance:

The filter is designed to withstand high temperatures, up to 1600°C, without melting or degrading. This makes it ideal for use in demanding casting processes, such as steel casting.

4. Chemical Resistance:

The filter has excellent chemical resistance, which ensures that it can be used with a wide range of metals and alloys without any adverse reactions.

5. Cost-Effective:

Our Alumina Ceramic Foam Filter offers a cost-effective solution for improving the quality of metal castings. It is an affordable option that can save you money in the long run by reducing the need for rework and scrap.
