Why ammonia corrosion are common for copper and its alloys?

Ammonia is an important raw material for the manufacture of nitric acid, ammonium salt and amine. Ammonia is gas at room temperature and can be liquefied under pressure. Most metals such as stainless steel, aluminum, magnesium, titanium, etc. have excellent corrosion resistance to ammonia gas, liquid ammonia and ammonia water, except copper and other copper […]

Heat treatment of Beryllium Copper C17200

The heat treatment of Cu-Be alloy is mainly solid solution annealing and aging hardening. Unlike other copper alloys whose strength is obtained only by cold machining, wrought copper beryllium is obtained by cold machining and hot aging hardening processes up to 1250-1500 Mpa. Aging hardening is often referred to as precipitation hardening or heat treatment. […]
