Title:
非常に高い強度を有する超耐たわみ性、且つ耐融解性フィン材料
Document Type and Number:
Japanese Patent JP6472378
Kind Code:
B2
Abstract:
Method for producing AIMn strip or sheet for making components by brazing and products obtained by said method, in particular fin materials of thin gauge used in heat exchangers. Rolling slabs are produced from a melt with <0.3% Si, ≦0.5% Fe, ≦0.3% Cu, 1.0-2.0% Mn, ≦0.5% Mg, ≦4.0% Zn, ≦0.5% Ni, ≦0.3% each of group IVb, Vb, or Vib elements, and unavoidable impurity elements, as well as aluminum that, prior to hot rolling, are preheated at <550° C. to control the number and size of dispersoid particles, hot rolled into a hot strip, cold rolled into a strip with total reduction of at least 90%, and heat treated to obtain a 0.2% proof stress value that is 50-90% of its proof stress value in the as cold rolled condition and in a range between 100 and 200 MPa. The strip may alternatively be produced by twin-roll strip casting.
