Ceramic foam filters and deep bed filters both remove non-metallic inclusions from molten aluminum, but they use different filtration structures and equipment configurations. Ceramic foam filters are porous ceramic plates installed in filter boxes, while deep bed filters pass molten metal through a packed bed of granular filtration media. The better option depends on production […]
Aluminum melt purification requirements vary with the final product, alloy specification, and downstream processing route. Thin-gauge battery foil demands strict control of inclusions and hydrogen-related defects. Aluminum sheet and strip require different cleanliness levels depending on their application, while standard extrusion billets and high-performance billets have different acceptance criteria. Selecting the right combination of degassing, […]
The right aluminum melt purification system depends on the final product’s cleanliness requirements, casting process, and production capacity. Battery foil stock generally requires stringent hydrogen and inclusion control, aluminum sheet and strip need treatment matched to their specific applications, and extrusion billets require a configuration suited to their intended use. AdTech supplies online degassing equipment, […]
Selecting a refractory lining for a high-magnesium aluminum degassing box requires more than checking its maximum service temperature. Magnesium can react with susceptible silica-bearing refractory phases, while molten alloy penetration, thermal cycling, and reaction-induced cracking can accelerate lining deterioration. The right material should be evaluated for chemical compatibility, porosity, resistance to molten aluminum penetration, structural […]
AdTech has taken another step in expanding its ceramic filter plate manufacturing capabilities. On September 21, 2026, the company’s third high-temperature firing production line, together with its supporting automation equipment, completed commissioning and officially entered production. The new line will primarily manufacture European-standard and phosphorus-free ceramic filter plates, strengthening AdTech’s capacity to produce high-end filtration […]
An alumina ceramic foam filter (CFF) is used to remove non-metallic inclusions from molten aluminum before casting. Selecting the right filter requires more than choosing a PPI rating: filter dimensions, available filtration area, metal flow rate, sealing design, and filter box compatibility all affect performance. AdTech supplies ceramic foam filters for aluminum casting applications, with […]
The three-day ALUMINIUM 2026 exhibition in Düsseldorf is coming to an end today. From October 6 to 8, AdTech Metallurgical Materials Co., Ltd. has been exhibiting at Booth 6M18, meeting customers and industry professionals from different parts of the aluminum industry. For AdTech, the exhibition has been less about simply displaying products and more about […]
This October, AdTech Metallurgical Materials Co., Ltd. will travel to Düsseldorf, Germany, to take part in ALUMINIUM 2026, taking place October 6 through 8 at Messe Düsseldorf. Our team will be at Stand 6M18. For AdTech, this is an opportunity to meet people from across the aluminum industry and talk about a part of production […]
For aluminum casting operations, melt quality has a direct influence on casting performance and final product consistency. Among the factors that need to be controlled before casting, dissolved hydrogen is particularly important because excess hydrogen can contribute to gas porosity during solidification. This makes molten aluminum degassing an important part of aluminum melt treatment. A […]
Molten aluminum purification is not a single-step process. No single treatment method can efficiently remove dissolved hydrogen, oxide films, and solid non-metallic inclusions at the same time. For most aluminum casting operations, a combination of furnace treatment, rotary degassing, and molten aluminum filtration provides a practical way to improve melt cleanliness and casting quality. A […]
