[origin: FR2772657A1] A brazing paste, comprising a brazing metal matrix (10) containing a homogeneous dispersion of superelastic alloy particles (5) coated with a wettable metal, is new. An Independent claim is also included for production of the above by incorporating the superelastic alloy particles (5) in the brazing metal matrix (10). Preferred Features: The paste contains 5-30 vol.% of 1-50 mu diameter spherical superelastic alloy particles (5) which consist of Ni-Ti, Cu-Zn-Al or Cu-Al-Ni shape memory alloy and which are coated with Cu, Ni, Au, Sn, Ag or Pb.
