Abstract Gold alloys used in jewellery applications are designed to improve mechanical properties and reduce cost. Compositions of low carat gold alloys, in particular 9 carat gold, vary from ternary gold-silver-copper alloys to quaternary alloys where zinc is added to counteract the red colour induced by copper. Although gold is inherently noble and exhibits high resistance to corrosion, these alloys have shown susceptibility to stress corrosion cracking (SCC), however, little is known about their susceptibility to other forms of corrosion such as pitting, intergranular corrosion and selective leaching.
