For our primary aluminium powders, we are using the most modern state of the art technology for the atomizing process by air or protective gas to generate fine and ultrafine spherical and spattered powders out of the melt. The grinding and milling of aluminum foils and scrap in our mechanical mills represent a costeffective alternative.

Using an Angle Grinder. An angle grinder is a power tool that can be used to cut and grind aluminum. To make aluminum powder with an angle grinder, start by cutting the aluminum into small pieces. Place the pieces into the angle grinder and turn on the power. As the aluminum spins, the blades will break the material down into a fine powder.

Pure aluminium in a ball mill forms spherical particles that get smaller until the competing process of particles rejoining forms a limiting fineness. With the right additives and pretreatment the aluminium tears into smaller particles with much more surface area than spheres, and keeps getting finer as milling progresses.

The first step in producing an aluminum wire rod is melting and casting. This involves heating the metal until it reaches its melting point, then pouring it into molds or moulded ingots. The molten metal is allowed to cool and solidify, forming a cylindrical shape known as an "ingot.". This ingot will be used for further processing later on.
