Definitions

  • the invention relates to a zinc casting alloy.
  • Alloys are used for cost-effective production of heavy-duty components used, for example used in the field of drive or connection technology become.
  • a zinc casting alloy known under standard designation Z410 (ZnAl4Cu1) commonly used for die casting has (in% by weight) 0.4-1.1% Cu, 3.5-4.3% Al, 0.02-0, 06% Mg and balance zinc and unavoidable impurities.
  • the impurities include (in% by weight) up to 0.05% Fe, max. 0.005% Cd, max. 0.005% Pb, max. 0.002% Sn, max. 0.02% Ni and max. 0.03% Si. The sum of all impurities is limited to less than 0.027 wt .-%.
  • the known zinc casting alloy achieves tensile strengths of 220-260 N / mm 2 , a yield strength R p0.2 of 170-200 N / mm 2 , an elongation at break A5 of 0.5-2 %, a hardness HB of 85-105 and bending fatigue strengths. which at 20 x 10 4 load changes 70 - 100 N / mm 2 amount.
  • the problems described above could not be solved in principle by using a higher alloyed zinc casting alloy, which is available on the market under the name Z430 (ZnAl4Cu3).
  • This alloy has an increased copper content compared to the Z410 alloy with otherwise equal contents of Al, Mg and impurities, which may be 2.5-3.2% by weight.
  • the known Z430 alloy has tensile strengths of 280-350 N / mm 2 , a yield strength R p0.2 of 220-250 N / mm 2 , an elongation at break A5 of 2-5 % and a hardness HB of 50-65 .
  • the object of the invention is a Zinc alloy to create the most cost-effective Manufacture of castings that allows over a wide temperature range optimized material properties exhibit.
  • Zinc casting alloys according to the invention are based on Zinc melted that won in a recycling process has been. Unlike commercial fine zinc, whose production-related unavoidable components on one Minimum reduced, recycled zinc has higher levels on impurities. These can be up to 0.135% by weight, preferably up to 0.100 wt .-%, wherein Minimum levels of 0.05 wt .-% and more are the rule. Surprisingly, it turned out that one In spite of this, the cast zinc alloy is composed according to the invention the circumstance that they are due to the use of Recycled zinc a significantly higher proportion Impurities, has a property profile, that the characteristics of the state of the art known, usually for the production of Zinc castings used alloys is superior. This success sets itself even if the proportion the impurities in the recycled zinc 0.075 wt .-% and is more.
  • the load at the one with a vertical load one from a Alloy manufactured specimen to a break comes, in each case at least 40% to 80% is higher than the load at which a corresponding, from the known Z410 alloy sample breaks.
  • the span in the Cu of the alloy according to the invention can be added is that the for the respective application optimized properties of the Alloy can be adjusted.
  • the alloy according to the invention Cu contents from 3.50 to 4.90% by weight.
  • invention Cast alloys with Cu contents in this range can be shed at lower casting temperatures, at which also the wear of the casting machine is reduced.
  • the impurities present in a zinc casting alloy according to the invention are usually composed of the elements which are also present in the case of fine zinc-based alloys.
  • the individual contents of these elements should be limited as follows (in wt .-%): Fe ⁇ 0.075%, pb ⁇ 0.005%, CD ⁇ 0.004%, sn ⁇ 0.003%, Ni ⁇ 0.02%, Si ⁇ 0.02%, Mn ⁇ 0.002%.
  • a zinc casting alloy E1 containing 5.500% by weight of Cu, 4.000% by weight of Al and 0.050% by weight of Mg is melted and 50 is used as specimens Determining the breaking load used wedge pieces have been cast, which are used in a drive gear. Subsequently, the wedge pieces have been subjected to a mixed load of tensile and compressive forces, which have been produced in the form of a pressing acting on the inclined surface of the wedges on a surface of 60 mm 2 . This pressure was increased in each case, until it came to the break of the wedge. It was found that in the average of 50 samples the fracture occurred at a pressure of 255 bar.
