The 7075 aluminum extrusions have many good qualities, including remarkable strength. However, the material can present notable challenges during machining or fabrication. It has unique metallurgical characteristics that can make machining challenging. Compared to other aluminum alloys, 7075 aluminum is harder. You might need special cutting tools and techniques when cutting extrusions from this alloy. Heat buildup during machining is also a potential challenge, a reason why we recommend the use of cooling and lubrication solutions. When done properly, machining 7075 aluminum extrusions can result in precise tolerances, a smooth surface, and excellent products.
