Definitions

  • the invention relates to rolled or spun aluminum alloy products of the series 4000 having both good mechanical strength and good resistance to corrosion.
  • Aluminum alloys containing silicon as the main alloying element are widely used for manufacturing molded parts. They are however more rarely used in the form of rolled or extruded products. Uses in form of extruded bars or profiles are linked to good resistance to wear and temperature alloys with a high silicon content, and mainly concern the manufacture of parts mechanical components such as connecting rods, drive shafts, bearings and components motors and compressors.
  • the Si content is between 1.4 and 2%, the copper content between 0.3 and 0.5%, the manganese content between 0.9 and 1.2%, the iron content less than 0.7% and the magnesium content less than 0.15%.
  • the products according to the invention are distinguished from 4015 alloy products by a higher copper content and lower magnesium content. So unexpected, a controlled copper content of between 0.2 and 0.8%, and preferably between 0.3 and 0.5%, leads to an improvement in resistance to corrosion, whether it is pitting corrosion or filiform corrosion.
  • This corrosion resistance is also favored by a low content of magnesium, less than 0.20%, and preferably 0.15%.
  • the drop in resistance mechanical resulting from the reduction of the magnesium content is more than compensated by the increase in the copper content, so that the resistance mechanical is higher than for similar products in 4015.
  • the products according to the invention exhibit corrosion resistance in the naked state, measured by the depth of bites in the SWAAT test (Sea Water Acetic Acid Test) according to ASTM G85, significantly better than that of alloy 4015. They can therefore be used in industrial environments, for example for insulation panels for cables or pipes in workshops, signage and the building ..
  • the alloys A and B are according to the invention, the alloys C to E are alloys 4015.
  • the manufacturing range is conventional, and includes a casting of plates, a hot rolling, cold rolling, and final work hardening in the H12 state.
  • the sheet of alloy A according to the invention has better mechanical resistance than sheet of the same thickness in alloy C. which contains less copper but more magnesium.
