Aluminum extrusion is a versatile manufacturing process that involves forcing heated aluminum billets through a die to create specific shapes and profiles. This process is widely used in various industries due to aluminum's unique properties, such as its lightweight nature, corrosion resistance, high strength-to-weight ratio, and recyclability[2]. Michigan, with its rich industrial history and strong manufacturing base, is home to numerous companies that specialize in aluminum extrusion. These companies serve a diverse range of industries, providing custom and standard aluminum extrusions tailored to meet specific needs[1][2][5]. This article explores the key industries that utilize aluminum extruders in Michigan, highlighting the applications and benefits of this essential manufacturing process.
