2011 - Characterization of 14-Karat Gold Alloys

0.00

Data about the characterization of 18-karat gold alloys were presented by Progold at the 2010 Santa Fe Symposium. In this paper we are going to discuss the chemical and physical properties of 14-karat red-, yellow-, and white-gold alloys. As with 18-karat gold alloys, knowing the alloy's properties enables us to choose the most suitable composition for each particular production process. Color is fundamental to the selection of a gold alloy but how to get the desired color and favorable working properties is a question. In this paper we analyze how small additions of some elements may improve some important characteristics in the production cycle. The goal is to correlate the features of each alloy with its chemical composition so you can choose the optimum 14K gold alloy for each use. The methods and tests used to collect data are not presented here as they are the same used with the 18K gold alloys reported in the 2010 proceedings.
