Disclosed is a NiCr-based brazing alloy including, on the basis of mass %: 15%<Cr<30%; 3%<P<12%; 0%<Si<8%; 0.01%<C<0.06%; 0%Ti+Zr<0.1%; 0.01%<V<0.1%; 0%Al<0.01%; 0.005%<O<0.025%; 0.001%<N<0.050%; 0%Nb<0.1%; and the balance being Ni and incidental impurities. Inequality (1): 0.20.24V %/C %1.0 is satisfied if the alloy contains no Nb, and Inequality (2): 0.2(0.24V %+0.13Nb %)/C %1.0 is satisfied if the alloy contains Nb. Also disclosed is an inexpensive NiCr-based brazing alloy containing a trace amount of V for use in the production of stainless steel heat exchangers and other steel articles. The alloy has a low liquidus temperature and high corrosion resistance, and achieves high brazing strength.

A metal joined body in which a joint is formed from a first metal member and a second metal member. Brazed joint portions provided intermittently with a brazing material and solder joints filling the spaces between the brazed joint portions with a solder having a fusion point lower than the brazing material, are formed at a seam of the joint. The resulting metal joint has excellent sealing properties and little thermal strain.

An electrical connector assembly method, including the steps of: step 1: providing a terminal having a soldering portion; step 2: heating the soldering portion to a melting temperature of a solder; step 3: providing the solder, and press-fitting the solder to the soldering portion by a jig, so that the solder is fused and fixed to the soldering portion; and step 4: inserting the terminal fixed with the solder into an insulating body. Because only the soldering portion of the terminal is heated, less thermal energy is needed, thereby saving energy and reducing the production cost of the electrical connector. Moreover, the insulating body does not need to be heated, thus preventing the insulating body from being warped and deformed due to heat.
