which parts are case hardened and because no quenching is required after exposure to the ammonia gas. Heat-Treatment of Nonferrous Metals Aluminum Alloys In the wrought form, commercially-pure aluminum is known as 1100. It has a high degree ... said to be in the H condition. The most widely used alloys in aircraft construction are hardened by heat-treatment rather than by cold-work. These alloys are designated by a somewhat different set of symbols: T4 and W indicate…
