Aluminum - A Uniquely Malleable and Ductile Metal Created from Bauxite
Serving the machining needs of clients spanning the country, Western Extrusions maintains a 750,000-square-foot facility and has five extrusion presses which include a pair of state-of-the-art large diameter presses. The Western Extrusions team takes pride in meeting the needs of clients for extruded aluminum projects of a wide range of sizes and dimensions.
The most common element within the earth’s crust, aluminum trails only oxygen and silicon in worldwide abundance. Along with gold, it is among the most malleable of metals and not typically strong enough to be used by itself. For this reason, most aluminum products actually involve a combination of smaller amounts of metals such as copper, manganese, magnesium, and silicon.
Aluminum is chemically extracted from bauxite, which is typically mined from the earth’s surface. This process involves heating the ore with a sodium hydroxide solution until the aluminum separates from the ore. The aluminum is then subject to a heating process that involves electrification of a molten substance before it solidifies as a hardened aluminum product that can be used for everything from cans to construction materials.
