Definitions
- the invention relates to a deep-drawn and weldable AlMgSi type aluminum alloy in the form of strips or sheets and a process for their manufacture.
- the inventor has the Task, an alloy of the type mentioned to create a good strength compared to alloys improved forming behavior according to the prior art with the least possible springback after deep drawing shows.
- the alloy composition according to the invention enables the production of deep-drawn body parts with optimal Mechanical strength and Forming behavior.
- zinc By adding 0.05 to 0.4% by weight, in particular 0.1 up to 0.3% by weight zinc can further increase the strength combined with a slight improvement in formability can be achieved.
- the average grain size in the sheet should not exceed 80 ⁇ m and is preferably less than 60 microns.
- the alloy according to the invention is carried out in the usual way Continuous or strip casting, hot and cold rolling into one Sheet or strip processed.
- Continuous or strip casting hot and cold rolling into one Sheet or strip processed.
- the solution annealing in one Continuous belt furnace in a temperature range of 520 ° C up to 580 ° C or up to the solidus temperature of the alloy is carried out.
- Optimal mechanical strength values and properties can be achieved if the alloy is preferably at the latest 60 min after the solution annealing of a so-called stabilization annealing of a maximum of 24h in a temperature range from 50 ° C to 150 ° C.
- the alloy can be rolled to final thickness, solution annealed and then a temperature range of 160 ° C to 220 ° C can be thermoset. It is advantageous also a maximum of 25% deformation after solution annealing and before final annealing in the temperature range mentioned.
- the alloy according to the invention is particularly suitable for the production of deep-drawn body parts.
