  • the invention relates to a method for producing a clad aluminum alloy sheet for brazing purposes and a sheet produced by the method.
  • brazing sheet typically comprises a core alloy and at least one cladding layer.
  • Fe-levels in core alloys intended for tube stock applications are deliberately kept low in order to achieve a good corrosion resistance in the post-brazed condition. Consequently, the production of such tube stock materials demands the use of high grade primary aluminum that does not allow any significant re-use of aluminum brazing sheet scrap material.
  • brazing sheet scrap During the production of brazing sheet, large quantities of brazing sheet scrap become available. This scrap contains significant levels of alloying elements, particularly silicon, copper (Cu) and iron. These levels of alloying elements severely limit the re-use of the scrap, particularly for producing new brazing sheet long life core alloys.

Cladding the core alloy with an Al-Si alloy on at least one side with a clad ratio of 3-25%; c.

  • brazing sheet scrap is at least 25% in weight of the total metal added to prepare the charge, for producing an aluminum alloy sheet comprising chromium containing (AI 1 Fe 1 Mn) and (AI 1 Fe 1 Mn 1 Si) intermetallics.
  • the core alloy ingot may be a conventional ingot, or a continuously cast slab, thin cast slab or cast strip.
  • the clad ratio is defined as the percentage of clad layer thickness of the total thickness of the entire brazing sheet comprising the core alloy and the clad layer or layers.

  • AA4343 AA4145
  • Si is an important alloying element in the alloy according to this invention.
  • the addition of Si results in an increased solution and precipitation hardening of the alloy. Above 1.3% it may result in the formation of detrimental low-melting eutectics and also in the formation of large intermetallic particles.
  • a more suitable minimum Si content is 0.75%.
  • a Si-level at this medium range is regarded as detrimental.
  • An advantage of this medium range Si-content is that the alloy has a tolerance for impurity elements, and allows this alloy to be composed from large amounts of scrap material.
  • the sum of Si+Mn is in the range of 1.45-2.75%, and more preferably in the range of 1.5-2.75%, because this allows for a good compromise in desired properties of the alloy such as post-braze strength and corrosion resistance.
  • Si is between 0.4 and 0.7%.
  • Mn is also an important alloying element in the alloy according to this invention.
  • a Mn-level between 0.5 and 1.5% proves to result in satisfactory properties over the entire range.
  • a preferred lower limit for the Mn content is 0.55%.

  • the addition of chromium and the use of scrap as charge material alters the composition of the intermeta ⁇ ics, thereby preventing the formation of large Fe-Mn intermetallics as a result of the high Mn content.
  • the Mn level should not exceed 1.5%. However, above 1.2% Mn a successful casting requires judicious combination of casting parameters.
  • Mg increases the strength of the alloy significantly, but has a detrimental influence on controlled atmosphere brazeability because it tends to interact with the flux applied. For this reason the Mg content is restricted to a maximum of ⁇ 0.25%.
  • Fe is present in all known aluminum alloys.
  • An Fe-content between 0.06 and 0.60% proved to result in a suitable compromise of formability, corrosion performance and solidus temperature.

  • a suitable Fe content is in the range of 0.25 to 0.48%, and allows for a good compromise in desired properties of the alloy such as post-braze strength and corrosion resistance, while the alloy can be manufactured without great difficulties using scrap material.
  • Cu is preferably included as a strengthening or hardening component. Above copper contents of 1.2%, successful casting of commercial size ingots can be affected due to hot cracking. A suitable maximum for the Cu content is up to 1.05%. A suitable minimum for the Cu content is 0.30%. Preferably the Cu- content is between 0.33 and 1.0% as a compromise in achieving post-braze strength, corrosion resistance and brazeability. In an embodiment of the invention the Cu-content is between 0.55 and 1.0 wt.%. With regard to the role of copper in corrosion resistance, the most recent work shows rather a favourable influence, while the copper remains in solid solution.
  • Zn addition must remain below 0.25% in order to avoid a too high susceptibility to generalised corrosion.
  • a more preferred maximum is 0.10% to reduce the tendency to generalised corrosion even further.

  • the total of these elements should not exceed 0.3%.

  • Zr in a range of up to 0.2% may optionally be used as alloying element to the alloy of this invention in order to further improve the strength of the alloy in the post-braze condition. Further, this element may be tolerated as an impurity element without affecting the properties of the alloy.
