Filter for Molten Aluminum

Overview

Characteristics

• Excellent filtration efficiency

  Relative large inclusions are trapped on the filter surface (surface filtration), while smaller inclusions are trapped inside the filter (internal filtration). Internal filtration performance is proportional to the specific surface area inside the filter, and needle-like boric acid aluminum crystals increase the surface area of the WHITE FILTER by more than 200 times compared to conventional products.

• Excellent corrsion resistance

  The boric acid aluminum crystals in the WHITE FILTER' s bond has no reaction to molten aluminum. Consequently, the bond has no corrsion at all after long use.

• Excellent properties at high temperature

  The strength of the WHITE FILTER doesn' t drop until extream high temperatures because, the melting point of Boric acid aluminum is at 1400°C or more. Also, as the thermal expansion of Boric acid aluminum is small, so is the thermal expansion of the WHITE FILTER small and the stress at high temp. is kept at a bare minimum.

Structure

Chamber for filter cartridge

Each filter cartridge set has an appropriate chamber to suit. There are also single and double type chambers.
