Metafilter®

Summary

Taking Aluminum Quality to the Ultimate Level

Standard molten aluminum filtration systems are essential for physically removing oxides and inclusions (non-metallic impurities) from molten aluminum, thereby improving the quality of ingots and finished products—particularly in terms of strength and workability.
It is positioned between the melting furnace and the casting machine and plays a crucial role in preventing the introduction of foreign matter that could cause defects.
Mitsui Kinzoku The company’s “Metafilter®” is based on a proprietary high-performance filter made of aluminum borate (Al₁₈BO₃O₂₇).
This filter reacts very little with molten aluminum and exhibits excellent corrosion resistance; by maintaining high inclusion capture performance over the long term, it contributes significantly to the manufacture of aluminum rolled products—such as aluminum beverage cans and foil—that require high quality.
