Definitions

  • the invention relates to an aluminum alloy with good electrical conductivity and good thermal conductivity for the production of die-cast components.
  • the standard alloy LM 6 to BS 1490 (AC 47000, AISiI 2 (Cu)) is used as standard.
  • the invention has for its object to provide a suitable for die casting aluminum alloy with respect to the known from the prior art alloys of improved electrical conductivity and thermal conductivity.
  • the sum of the elements manganese, titanium, vanadium and chromium is ⁇ 0.02% by weight.
  • a preferred field of application of the aluminum alloy according to the invention is the production of components with good electrical conductivity and good thermal conductivity, for example heat sinks for electronic components, by die casting.
  • novel alloy A and two comparative alloys B and C with the compositions shown in Table 1 were cast starting from a melt temperature of 660 0 C in die casting at a mold temperature of 15O 0 C to heat sinks for electronic components with a weight of 2.2 kg. After removal from the die, the samples were cooled in still air.
  • the comparative alloy B differs from the alloy A according to the invention essentially by an increased silicon content.
  • Table 1 chemical composition of the alloys in% by weight
