Alumina Ceramic Foam Filter - Molten Aluminum Filter
Our ceramic foam filter use good portiforium foam and high purity ceramic as raw material, can removes non-metal solid mixture from molten aluminium and aluminium alloy fusant effectively in your aluminium casting industry.
even aperture, high porosity, proper sinter, high strength of anti-flexing and anti-compression, effective filtering.
Function:
It is widely applied to the aluminium fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting.
Alumina ceramic foam filters are different from aperture specifications from 20 to 50ppi, with different sizes and shapes.
Chemial composition: Al2O3 is more than 85%, SiO2 is less than 15%
