6060 Aluminum for CNC Machining | Precision-Engineered Alloy
What Is 6060 Aluminum?
6060 aluminum is a heat-treatable alloy belonging to the 6xxx series, which is defined by the presence of magnesium and silicon as primary alloying elements. This particular composition creates Mg2Si (magnesium silicide) as the strengthening phase, providing 6060 aluminum with its unique properties. The alloy is often used in applications requiring moderate strength and excellent resistance to atmospheric and chemical corrosion.
While 6060 aluminum may not boast the same strength levels as 6061 or 6082, it excels in machinability and surface finish, making it a preferred material for aesthetically demanding or highly customized projects. The alloy is widely recognized for its high extrusion performance, allowing it to form complex shapes and profiles while maintaining structural integrity.
Key Properties of 6060 Aluminum
6060 aluminum offers an array of properties that make it highly versatile and dependable across numerous applications. Below are its most noteworthy characteristics:
