Aluminum powder is flammable and combustible. When aluminum powder mixes in the air, it can cause a dust explosion. When the powder reaches into touch with water, acid, or alkali, hydrogen with high flammability can occur. It also reacts with nitrates, sulfates, and other oxidizing agents and risks fire and explosion.

In open loop milling, the feed will go through the mill only one time, it is suitable in case the mill is performant enough to reach the desired PSD in 1 pass. It gives the simplest process. In closed loop milling, a system to separate the particles having a too large size to the ones having the desired size must be implemented after the mill.

This oxidation appears as white residue and pitting. Aluminum must be either powder coated or anodized to prevent oxidation. Mill finished aluminum surfaces will oxidize over a long period of time.

During the smelting operation, some of the carbon is consumed as it combines with oxygen to form carbon dioxide. In fact, about half a pound (0.2 kg) of carbon is used for every pound (2.2 kg) of aluminum produced. Some of the carbon used in aluminum smelting is a byproduct of oil refining; additional carbon is obtained from coal.

For example, when milling aluminum at 300-500 m/min, the temperatures may reach 600-800 degrees. However, if we increase the velocity up to 1200, the temperature goes down to less than 200 degrees, and it is a mere 150 degrees at 1800 m/min. From that point on cutting faster is pointless. Just consider, a mere 150-200 degrees!
