SF-Foundry is a manufacturer and supplier of casting materials, with its main products being Ceramic Foam Filters (CFF) for casting. The company is committed to providing high-quality filtration solutions for the foundry industry, serving the production of iron, steel, copper, aluminum and their alloys.
Core product: Ceramic Foam Filter
The ceramic foam filters produced by SF-Foundry are mainly used to filter high-temperature molten metals, effectively removing impurities, oxides and non-metallic inclusions, thereby improving the quality of castings. Its product features include:
Material types:
- Silicon carbide (SiC) filter: suitable for high-temperature casting, such as cast iron and cast steel.
- Alumina (Al₂O₃) filter: suitable for non-ferrous metals such as aluminum alloys and copper alloys.
- Zircon (ZrO₂) filter: suitable for high-demand casting environments, such as stainless steel and high-temperature alloys.
Pore size specification:
A variety of pore sizes (such as 10ppi, 20ppi, 30ppi, etc.) are available to meet the needs of different metals and casting processes.
- High temperature resistance: Can withstand high temperatures up to 1700°C, suitable for casting iron, steel, copper, aluminum and their alloys.
- High porosity: The porosity is usually 70%-90%, ensuring good filtration effect and melt fluidity.
