Abstract
Age hardening behaviour and consequent properties of several copper-ni ckel-tin alloys were studied by means of hardness and conductivity mea surements and analytical electron microscopy. Alloy CuNi6Sn7 (in wt%) was spinodally decomposing, and the properties of the alloy were fairl y similar to the well known alloy CuNi9Sn6. The decomposition behaviou r of low-nickel alloys CuNi(2 to 4)Sn7 was dependent on the age harden ing temperature. The electrical conductivity of the low-nickel alloys was not found to be significantly better than of the standard spinodal alloys. Long-term isothermal heat treatments indicated that the equil ibrium solubility of nickel and tin in copper is lower than expected.
