As a professional and reliable supplier of casting refractory materials, SF-Foundry has always been committed to providing high-quality metal melt filtration solutions to global customers. Our alumina ceramic foam filter is specially designed for aluminum and aluminum alloy casting, which can effectively improve the purity of castings and reduce the defect rate. It is widely used in automobiles, aerospace and other fields.
SF-Foundry Alumina Ceramic Foam Filter
Oxides, slag inclusions and bubbles in aluminum liquid are the main causes of pores, cracks and mechanical properties of castings. SF-Foundry Alumina Ceramic Foam Filter is made of high-purity alumina (Al₂O₃ ≥ 92%), with excellent high temperature resistance (applicable temperature up to 1250℃) and high mechanical strength, which can stably filter impurities in aluminum melt. Its unique three-dimensional mesh structure ensures smooth flow of molten metal, while efficiently capturing tiny inclusions, significantly improving the density and mechanical properties of castings.
SF-Foundry has advanced automated production lines and strict quality inspection systems to ensure that the pore size distribution, porosity and thermal shock resistance of each batch of alumina foam ceramic filters meet industry standards. We provide a variety of specifications from 10PPI to 60PPI to meet the needs of different casting processes, and can customize sizes and shapes according to customer requirements to adapt to various casting systems.
To meet the urgent needs of customers, SF-Foundry has optimized its global logistics system to achieve fast delivery and provide professional technical support to help customers optimize filtration solutions. Our products have been successfully used in many internationally renowned automotive parts manufacturers and have received unanimous praise.
SF-Foundry will continue to innovate and provide customers with more efficient and reliable casting filtration solutions. For more product information or samples, please visit our official website [www.sf-foundry.com] or contact our sales team.
