What's the difference between cast aluminum beams and extruded aluminum beams?

We all know that the density of aluminum is relatively low, so the weight of aluminum is much lighter. In addition, it has good toughness and good compatibility with other metals. After aluminum and other metals are made into aluminum alloys, they can have the metal properties of aluminum and other metals. At present, some high-power and large-format laser machines generally use cast aluminum. This kind of beam, which ensures the high speed and stability of the laser head, is also called industrial extruded aluminum. This kind of beam adopts a new structure, which solves the problems of beam mechanics and blank casting. In addition, the extruded aluminum beam has the advantages of corrosiveness and light weight, which can ensure the high-speed movement during laser processing, and also has excellent dynamic performance, which can realize the high-speed cutting of various graphics under the condition of meeting the accuracy.
