I am research student I need any one interest in casting of copper base alloy or high copper alloy with chrome in different ratios (0.46 - 5)% chrome and copper base alloy with aluminum in different ratios (3 -9)% Al ,I need know how can cast of chrome in molten copper that has 1907 C temp whereas the copper 1085 C, can I add chrome to molten copper as powder? Did the chrome dissolved in molten copper.
then I will try to make solution treatment to these alloy for strengthening (quenching and aging) to ...then I will to compare between these alloy with mechanical properties, corrosion and wear resistance. Please if you any one can help me to achieved these requirements. Did the copper chrome alloy has more than properties from copper aluminum alloy with the ratios above
Thank with my regards
You would need to know the solubility of chrome in copper to know how
much you can add but modern pewter (Britannia metal) is made by melting
tin and then adding the copper and stirring to dissolve the copper.
Copper has a much higher melting temperature than tin but will readily
dissolve up to a point.
