Definitions

  • the invention relates to a deep-drawable and weldable aluminum alloy of the AlMgSi type in the form of strips or sheets for the production of inner skin parts of a body, in particular an automobile body.
  • a method for producing the alloy and an inner skin part produced by deep drawing are also within the scope of the invention.
  • the alloy AA6016 and AA6116 which has become known as Anticorodal-120 (Ac-120), has established itself as the material for outer skin parts of car bodies.
  • the alloy AA5182 is also used as the material for the inner skin.
  • the alloy is intended to create the possibility of recycling the overall component of body parts consisting of outer and inner skin parts into the inner material (production scrap and end-of-life vehicles), with minor impurities from other automotive materials based on aluminum, steel, copper wires, etc should be catchable.
  • the contents (% by weight) of the alloy elements Mg and Si by the trapezoid ABCDE with the coordinates Si Mg A 0.50 0.35 B 0.50 0.60 C. 0.95 0.60 D 0.95 0.40 E 0.80 0.35 are limited and the alloy in addition Cu 0.15-0.45 Mn 0.05-0.20 Fe 0.05-0.55 Zn 0.05-0.50 as well as further alloy elements individually max. 0.10, total max. 0.30 and aluminum as the rest.
  • the contents (% by weight) of the alloy elements Mg and Si through the corner points are A * B * C * D * with the coordinates Si Mg A * 0.80 0.40 B * 0.80 0.55 C * 0.95 0.55 D * 0.95 0.40 limited.
  • the copper content of the alloy according to the invention is preferably between 0.2 and 0.4% by weight.
  • the average grain size in the sheet should not exceed 80 ⁇ m and is preferably less than 60 ⁇ m.
  • the alloy according to the invention is processed in the usual way by continuous casting or strip casting, hot and cold rolling to form a sheet or strip.
  • it has proven to be particularly advantageous if the solution annealing in a continuous belt furnace in a temperature range of 520 ° C. up to 580 ° C or up to the solidus temperature of the alloy.
  • Optimal mechanical strength values and properties can be achieved if the alloy is subjected to a so-called stabilization annealing of a maximum of 24 hours in a temperature range of 50 ° C to 150 ° C, preferably no later than 60 minutes after solution annealing.
  • the alloy can be rolled to its final thickness, solution-annealed and then heat-cured in a temperature range from 160 ° C to 220 ° C. Forming by a maximum of 25% after solution annealing and before final annealing in the temperature range mentioned is also advantageous.
  • the alloy according to the invention is particularly suitable for producing deep-drawn inner skin parts of a body, in particular an automobile body.
  • Ac120 is the preferred material for outer skin parts.
  • the contents (% by weight) of the alloy elements Mg and Si through the corner points A'B'C'D 'with the coordinates Si Mg A ' 0.50 0.35 B ' 0.50 0.50 C ' 0.75 0.50 D ' 0.75 0.35 limited, with a preferred area by the corner points A''B''C''D '' with the coordinates Si Mg A '' 0.55 0.35 B '' 0.55 0.45 C '' 0.7 0.45 D '' 0.7 0.35 is limited.
  • Both of the above-mentioned outer skin materials can be easily recycled into the inner material with the inner skin material according to the invention as the overall component of a body part.
  • the mechanical strength values and properties of the alloy according to the invention and the comparison alloy determined on sheet metal samples are compared below.
  • the sheets were deep-drawn in practical tests and subjected to further forming operations that are common in the manufacture of body parts. Tests were also carried out to weld the alloy according to the invention with Ac120. The practical tests have confirmed the improvements to be expected in the alloy according to the invention compared to alloys according to the prior art on the basis of the above measured values.
