Abstract

DC60 (10/02/15) This invention provides a method for producing AIMn designs or sheets for component making. By brazing, including products obtained by the above method. In particular, this method deals with fin material. The thin gauge used in the heat exchanger produces rolled slabs from molten material containing (less than) 0.3% Si, (less than or equal to) 0.5% Fe, (less than or equal to) 0.3% Cu, 1.0. -2.0% Mn, (less than or equal to) 0.5% Mg, (less than or equal to) 4.0% Zn, (less than or equal to) 0.5% Ni, (less than or equal to) 0.3% each of the group elements. IVb, Vb, or Vib, and its inevitable impurities, including aluminum, are the remainder of which are preheated, rolled slabs, pre-rolled at a heating temperature. Less than 550 ° C in advance to control the number and size of particles, displacement, and hot slabs.

To get 0.2% of the proof that is 50 -90% of its proof stress. In the condition as it is cold rolled to the proof stress In the range between 100 and 200 Mpa, an alternative could be produced by strip casting. The twin molten mixtures refine the micro-structure development during the completion of the process to provide the desired post-weld properties and the brazing performance in the mix with the appropriate transmission properties of the band, especially the latter strength. High cohesion combined with good flow resistance and low susceptibility. It is also possible to penetrate the liquid core during brazing, also for thin bands and slow bridging cycles, as well as relatively good formability.
