If you deal with exotic alloys like Inconel, titanium, Hastelloy, etc., this blog post is written especially for you.
Exotic alloys are alloys designed for high temperature applications (think aerospace), perform in corrosive environments (think underground), or have the highest strength to weight ratios (think earth moving applications). The machinability of these materials is NOT the first consideration. As much as it would be nice to have an aluminum firewall in a helicopter from the machinist’s viewpoint, as the pilot or passenger you want flame retardant and strong.
Some exotic materials can
