Abstract

A manganese-containing, cobalt-based alloy with zirconium, tantalum and carbon, and good cohesive joint connections, is provided.

First claim

1 - 9 . (canceled)

10 . A cobalt-based solder alloy comprising:
8% by weight-16% by weight of zirconium (Zr); 6% by weight-10% by weight of tantalum (Ta); 0.5% by weight-1.5% by weight of carbon (C), 8% by weight-12% by weight of manganese (Mn); at least 0.5% by weight of titanium (Ti); and having no boron (B), no silicon (Si), no germanium (Ge) and no gallium (Ga).

11 . The alloy as claimed in claim 10 , including 15% by weight of zirconium (Zr).

12 . The alloy as claimed in claim 10 , including 8% by weight of tantalum (Ta).

13 . The alloy as claimed in claim 10 , including 1% by weight of carbon (C).

14 . The alloy as claimed in claim 10 , including 10% by weight of manganese (Mn).

15 . The alloy as claimed in claim 10 , including 1% by weight of titanium (Ti).

16 . The alloy as claimed in claim 10 , consisting of zirconium (Zr), tantalum (Ta), carbon (C), manganese (Mn), cobalt (Co) and optionally titanium (Ti).

17 . The alloy as claimed in claim 10 , consisting of zirconium (Zr), tantalum (Ta), carbon (C), manganese (Mn), cobalt (Co) and titanium (Ti).

18 . The alloy as claimed in claim 10 , having at most 5% by weight of titanium (Ti).

19 . A powder having an alloy as claimed in claim 10 .

20 . A component comprising, in particular consisting of an alloy, as claimed in claim 10 .

21 . A soldering method using an alloy as claimed in claim 10 .

22 . The method as claimed in claim 16 , for soldering cobalt-based alloys which is carried out with heat treatment according to the prior art for a cobalt alloy that differs markedly from the alloy in particular that has no manganese.
