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, AlSi12 (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.
  • inventive alloy A and two comparative alloys B and C with the compositions given in Table 1 were cast starting from a melt temperature of 660 ° C in die casting at a mold temperature of 150 ° 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 3 the results of thermal conductivity measurements on the die-cast components made of the inventive alloy A and the Comparative Alloy C compiled.
  • the alloy A according to the invention exhibits 30 to 40% higher thermal conductivity than the comparative alloy C.
  • Table 1 chemical composition of the alloys in% by weight alloy Si Fe Cu mg Mn Cr tl V Sr A 8.66 0.60 0,006 0.001 0.005 0.001 0,008 0,006 0,012 B 9.40 0.63 0,008 0.001 0,006 0.001 0,008 0,008 0,008 C 10.0-13.0 0.6 0.1 12:10 0.5 - 0.2 - - alloy Mesastalle M1 [m / ⁇ mm 2 ] Measuring point M2 [m / ⁇ mm 2 ] A 26,06 24.48 B 24.35 23.09 C 22.08 21.21 alloy Number of measurements Temperature [° C] Sample thickness [mm] Thermal conductivity [W / mK] A 5 23 5.76 169.4 C 5 23
