Aluminum Pigments for Powder Coatings
The manufacture of aluminum pigments involves a specialized ball-milling process as the first stage. Here the atomized aluminum is ball-milled in the presence of solvent and a lubricant for a period of five to 40 hours. The lubricant is employed to prevent "cold welding" of the aluminum particles and thus avoid agglomerates.

Dry machining of aluminum for proper selection of cutting …
Machining of aluminum and its alloy is very difficult due to the adhesion and diffusion of aluminum, thus the formation of built-up edge (BUE) on the surface. The BUE, which affects the surface integrity and tool life significantly, affects the service and performance of the workpiece. The minimization of BUE was carried out by selection of proper cutting speed, …
