Definitions

  • the invention relates to aluminum alloys of the genus AIMgSi.
  • Such hardenable alloys are used in most of the manufacturing processes customary for aluminum alloys, for example for extrusion, rolling and hot pressing products. Such products can then be subjected to a heat aging treatment to achieve high strength.
  • the silicon and magnesium contents are selected and, if necessary, further alloying elements, for example up to 1% manganese, up to 1% copper or up to 0.35% chromium, are added.
  • Vanadium additives are also known to reduce the quenching sensitivity of extruded products.
  • An aluminum alloy is known from FR-A-2 078 965 with 0.4 to 1.0% Mg, 0.4 to 0.9% Si, 0.03 to 0.4% Cr, 0.03 to 0.2% Zr, up to 0.50% Zn, up to 0.30% Cu, up to 0.15 % Fe, up to 0.15% V, up to 0.10% Ti, 0.03-0.4 Mn and up to 0.008% B.
  • this object is achieved by an aluminum alloy which consists of 0.3 to 1.0% magnesium, 0.3 to 1.2% silicon, 0.1 to 0.5% iron, 0.05 to 0.20% vanadium, to 0.4% copper, a manganese content that is 1/4 to 2 / 3 of the iron content, and optionally a cobalt content that is 1/4 to 1/2 of the iron content, the rest is aluminum and impurities.
  • the fine-grained recrystallized state which is mainly due to the vanadium content, increases the cold formability of rolled and pressed products. Furthermore, it contributes to more uniform material properties and increases the strength level compared to coarse-grained recrystallized structure. In addition, the pressability is promoted in all its aspects.
  • Manganese which is in a range from 1/4 to 2/3 of the iron content, forms ternary phases together with aluminum, silicon and iron, which, thanks to their dimensions and distribution, significantly increase toughness. A manganese / iron ratio between 1/3 and 1/2 has proven to be particularly favorable.
  • Iron contents below 0.25% are particularly suitable to prevent edge cracking and the occurrence of press fleas during extrusion.
  • cobalt is added in a proportion by weight of 1/4 to 1/2 that of iron.
  • the ternary phases formed from Al, Co, Fe and Mn prevent embrittlement by means of their shape and arrangement. This also improves the pressability. However, if the manganese or cobalt content is above the specified limits, the pressability is reduced again.
  • the Cu content which contributes to the increase in strength without significantly increasing the required hot-forming force, should not exceed 0.25% if susceptibility to corrosion is to be specifically avoided.
  • Alloys 1 to 3 were processed into extruded products.
  • the alloys (E) according to the invention differ from the conventional ones (H) in particular in the better bendability of the thermally hardened profiles.
  • Alloys 4 were processed into hot pressed parts (forged).
  • the thermoformability of 4 U was significantly better than that of 4 H. While the hot-hardened forgings made of 4 H had considerable coarse grain and thus, in addition to the uneven and in places deep strengths, could not be decoratively anodized, the workpiece made of 4 E was characterized by very fine grain .
  • Alloys 5 were processed into sheet metal and deformed before heat hardening.
  • the sheet 5 E showed both in the deep drawing ability, as well in the toughness better values.
