Copper Alloys DataBase v1

Copper alloy calculator


A copper alloy is any combination of elements that contains more than 50% copper.

Copper alloys are generally preferred for electrical and corrosion resistant applications, but in the correct form; i.e. including Beryllium and/or Chromium can be as strong as carbon steel but with far greater corrosion resistance.

Whilst most data tables and collections contain only a fraction of the alloys and their properties, dependent upon availability, CalQlata has managed to compile a database of over 200 UNS copper alloys that includes more than 99.5% of their properties. Where reliable property values were unavailable they have been calculated and/or interpreted from known data and phase diagrams. For example, melting temperatures have been interpolated from the phase diagram(s) for all the alloy(s) included along with all bulk and shear moduli, which have been calculated from recognised formulas using known elastic moduli and Poisson's ratios.

Copalloys is a comprehensive and simple to use database of copper alloys and their principle physical properties (including chemical composition) in metric or Imperial units, all of which can be found and sorted with no more than two clicks of your mouse.

Data that has been calculated and interpreted by CalQlata is labelled thus; {Q}
