FREE-MACHINING ALUMINUM ALLOY

摘要

Various illustrative embodiments of a free-machining aluminum alloy composition and related methods are provided. The aluminum alloy composition can include an aluminum alloy and an effective amount of a graphitic material as a free-machining constituent. Free-machining means the graphitic material is capable of modifying the machining character of the aluminum alloy by affecting the generation of chip-shaped machining debris and/or the friction between the machining tool and the workpiece.
