Coatings and Ceramic Filters for Molten Metal Filtration

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent presents a new filter material and ceramic filter system for filtering molten aluminum and magnesium metals. The filter is made using a special sintered material called MgAlON, produced from aluminum nitride, magnesium oxide, and aluminum oxide in a nitrogen-rich atmosphere. This improves the filtering process during metal casting.

Use CasesContent extracted from patent full text and abstract with AI.

• Filtering impurities from molten aluminum and magnesium during metal casting processes
• Use in foundries and metal processing plants to improve product quality
• Application in the manufacturing of high-purity aluminum and magnesium components for automotive or aerospace industries
• Integration into existing metal filtration systems as advanced filter modules

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced filtration efficiency for molten metals, leading to higher purity end-products
• Improved durability and chemical resistance due to the special MgAlON composition
• Reduces defects in cast metal parts, increasing their reliability and performance
• Can be used with both aluminum and magnesium, offering broader application range
• Potential for longer filter lifetime, lowering operating costs in metal processing
