More info

Alumina (Al2O3) Ceramic Foam Filter is designed for filtering molten aluminum and aluminum alloys in continuous casting, semi-continuous casting, gravity casting, and low-pressure casting processes. We offer two types: Large - Plate Alumina Ceramic Foam Filter, which is suitable for high-volume aluminum filtration and is also used in non-ferrous precision casting, high-temperature gas filtration, sound absorption, and as a catalyst carrier; and Small - Block Alumina Ceramic Foam Filter, which effectively captures both large and micron-sized impurities to enhance surface finish, optimize mechanical properties, and improve the microstructure of aluminum products. These filters are widely used in the production of aluminum profiles, aluminum foil, and other aluminum-based applications. Heeger Materials provides high-quality Alumina (Al2O3) Ceramic Foam Filter with stable performance and reliable results.

Alumina Ceramic Foam Filter Key Features

High porosity enables the effective filtration of inclusions in molten aluminum.
Reduces defect rates and improves casting quality.
Enhances surface quality and overall product performance.
Refines the microstructure and shortens the solidification time.
Improves mechanical properties and reduces rework.
Boosts product yield and economic efficiency.

Alumina Ceramic Foam Filter Usage Precautions

Avoid direct impact of molten metal on the filter. If unavoidable, pouring height should not exceed 300mm.
Preheat the filter together with the riser or pouring spout to prevent the steel liquid from solidifying and blocking the filter.
Before usage, remove surface slag from the filter with air blowing.
It is recommended to use an open pouring system to prevent air entrapment.

Alumina Ceramic Foam Filter Applications

Aluminum and Aluminum Alloy Casting: Effectively filters molten aluminum during continuous, semi-continuous, gravity, and low-pressure casting processes to remove micron-sized inclusions and stabilize metal flow.
Improving Casting Quality: Enhances surface finish and internal structure by capturing both large and fine impurities, leading to improved mechanical properties and higher product yield.
Non-Ferrous Metal Precision Casting: Used in the filtration of other non-ferrous metals due to its excellent thermal resistance and fine-pore structure.
High-Temperature Gas Filtration: Acts as a ceramic membrane for high-temperature filtration systems, providing thermal stability and chemical resistance.
Catalyst Support and Acoustic Applications: Its unique porous structure makes it suitable for use as a catalyst carrier and in sound-absorbing materials in industrial or environmental applications.
