Definitions

  • the invention is therefore based on the object of specifying a copper alloy which has a high thermal conductivity, a high mechanical strength, in particular at temperatures above 300 ° C. and a high degree of hot plasticity.
  • the material should be used in particular for the production of continuous casting molds.
  • a copper alloy consisting of 0.05 to 0.4% zinc, 0.02 to 0.3% magnesium, 0.02 to 0.2% phosphorus, the rest copper and production-related impurities, the alloy can optionally contain 0 to 0.2% silicon and / or 0 to 0.15% zirconium.
  • silicon up to 0.2%, preferably up to 0.1%, has a positive effect on the hardness and thus on the wear resistance.
  • the invention further relates to a method for producing a copper alloy as described above.
  • the alloy is then hot worked at 300 to 550 ° C for 1 to 5 hours and finally cold worked by at least 10%.
  • Cold working of at least 10% between hot working and aging at 300 to 550 ° C has a positive effect on the state of homogenization and the combination of properties.
  • the alloy is particularly advantageous for the alloy to be thermoformed above the temperature of the maximum solubility of the alloy components and then to be quenched by at least 750 ° C. With this measure, an additional curing effect can be achieved. However, solution annealing can also be carried out separately from hot working.
  • the technological properties of the alloy are somewhat more favorable if the hot working at solution annealing temperature is heard and quenched and then the operations described above are followed. By eliminating intermediate phases from the copper matrix, even more favorable strength and conductivity values can be achieved.
