    摘要: A homogenous brazing material essentially consisting of relatively low amounts of silver and nickel together with copper, zinc, and other constituents is provided. The brazing material has a working temperature exceeding 630° F. and is preferably between about 1250° F. and 1500° F. The brazing material preferably has about 30 percent by weight of silver, about 36 percent by weight of copper, about 32 percent by weight of zinc, and about 2 percent by weight of nickel. The addition of nickel in the above-specified amount improves resistance against interface corrosion in aqueous solutions, aids in the strength of the alloy, and provides improved wettability on ferrous and non-ferrous substrates. The brazing material may also include a flux, such as a core or a coating.

    摘要: Disclosed is a Pb-free solder alloy consisting of, in mass %, 0.1-1.5% of Ag, 0.5-0.75% of Cu, Ni in an amount satisfying 12.5≦Cu/Ni≦100, and the balance of Sn and unavoidable impurities. The solder alloy preferably contains, in mass %, 0.3-1.2% of Ag and 0.01-0.04% of Ni. Also disclosed is a solder ball obtained by spheroidizing the solder alloy. In addition, the solder alloy is suitable for a solder joint onto an Ni electrode. The solder alloy has excellent drop impact resistance, while being suppressed in decrease of joining strength under high temperature conditions for a long time.
