Ceramic Filter for Aluminum Alloy -sales@aluminiumceramicfiber.com

Metal when molten in the air will make an oxide skin called slag that floats on top and can be skimmed off. Often, the impurities in metal will collect in this slag. If the slag is poor, additives are mixed in to make a slag and clean up the alloy that way. Another trick is to sparge the melt with a tube of clean inert gas that as it bubbles up to the top, takes dissolved gases with it. Dissolved gasses are bad for many alloys. Then, especially for aluminum alloy, you physically filter the metal as you pour it using a ceramic filter to remove particles, like slag, from within the melt.

The high temperature resistance and chemical resistance of the filter material plays a vital role in this process.

Ceramic Filter for Aluminum Alloy

Alumina ceramic foam filter is better for aluminum alloy filtration and removing all solids mixed in the molten metal, these foam or cast filters work well. This technology is widely used in aluminum foil manufacturing. In fact, it allows the aluminum metal to be deeply filtered. Filtration is an important procedure included in many industrial processes. The main purpose of this technology is to improve product quality by removing impurities from metals. The filter used in this process must adapt to the corrosive environment and high temperature during the filtration process.

Other types of ceramic foam filter products are also used in different casting processes. The SiC ceramic foam filter is one of the most widely used filters in various applications. The market for these filter products continues to grow globally. Approximately 80% or more of durable products are made of castings.

Casting itself is a multifaceted process, divided into many categories. Die casting is the most commonly used one and involves injecting molten material or metal into a mold under sufficient pressure. Through curing, the desired product shape is completed. The molten metal filtered through the ceramic filter contains unnecessary fillers. By providing the basic properties of the metal used, the final product can be made more durable. New technology makes the filtration process faster and simpler.
