Alumina Foam Filter for Aluminum Casting
Specifically branded as the Alumina Foam Filter for Aluminum Casting, this product is the result of focused engineering for the aluminum foundry industry. It leverages the optimal properties of alumina in a resilient foam structure to provide deep-bed filtration. This process not only removes harmful inclusions but also promotes a quiescent, laminar metal flow into the mold cavity, which is critical for producing high-integrity, porosity-free aluminum castings.
Product Description
The Foundry's Choice: Premium Alumina Foam Filter for Aluminum Casting
Specifically branded as the Alumina Foam Filter for Aluminum Casting, this product is the result of focused engineering for the aluminum foundry industry. It leverages the optimal properties of alumina in a resilient foam structure to provide deep-bed filtration. This process not only removes harmful inclusions but also promotes a quiescent, laminar metal flow into the mold cavity, which is critical for producing high-integrity, porosity-free aluminum castings.
Detailed Features & Customization
Core Design: Alumina foam ceramic structure, offering an excellent balance of filtration efficiency, thermal shock resistance, and molten metal compatibility.
Standard Specifications: As per our DT-1 series data, it ensures a compressive strength ≥0.8 MPa and high porosity (80-90%) for efficient filtration with controlled metal flow rates. Refer to the melt speed chart (e.g., 90-170 kg/min for 305*305*50mm) for sizing guidance.
Available Forms: Primarily square and round. Thicknesses of 10, 20, 22, 25, 30, 40, and 50mm are common. We excel at customization - whether you need a small 30mm filter or a complex bespoke shape for a proprietary gating system.
Gasket Options: Available with your choice of normal cotton, expandable, or ceramic fiber paper gasket for a secure fit in your filter box.
Industry Application
This filter is indispensable across all aluminum casting sectors, including automotive (transmission cases, suspension parts), aerospace (structural brackets), and consumer electronics (heat sinks). It directly enhances the mechanical properties and surface finish of final cast components.
