When producing metal parts, we have a lot of solutions in production, soft metals are often used in sheet metal fabrication and CNC machining.
Elemental aluminum is soft and highly mixable, making it a weak mechanical candidate. Aluminum is instead generally mixed with a mixture of other elements such as silicone, copper, magnesium or zinc, then heat-treated to produce the strong, lightweights currently used in aircraft, cars, and a range of consumer goods.
Let's discuss two aluminum types: 6061-T
