Inclusion in aluminum
 at Leonard Aluminum Utility ...)
An inclusion is a solid particle in liquid aluminium alloy. It is usually non-metallic and can be of different nature depending on its source. Inclusions can create problems in the casting when they are large and in too high concentration. Here are examples of problems related to inclusions: Pinholes in light gauge foilFlange … See more Oxide films In contact with ambient air, liquid aluminium reacts with the oxygen and form an oxide film layer (gamma-Al2O3). This layer becomes thicker with time. When molten aluminium is … See more Several methods exist to measure the inclusion content in liquid aluminium. The most common methods are PoDFA, Prefil, K-Mold and LiMCA. Measuring the inclusions is of great help to understand the impact of furnace preparation, alloying practice, feedstock … See more In order to get a good quality product, removing the inclusion becomes necessary.
