According to the phase transformation rule of nickel, before melting in solid phase region, using the subsection reduction method to reduce the harmful impurity sulfur and phosphorus in nickel and then using slagging method and vacuum electron to refine. Compared with the traditional nickel wire manufacturing process, it is obvious that the advantages of using international technology of direct forging and rolling of nickel plate after the pretreatment of nickel plate. First, it saves time of the traditional process of smelting, planing surface, hot forging, hot rolling and other processes, so that the production cycle is greatly shortened. Secondly, the process avoided some problems such as the declining metal purity, increased resistance and poor plasticity caused by adding accessories in the melting process. The process can produce high purity nickel wire without changing the chemical composition and the purity of the original electrolytic nickel metal plate, so that it can ensure that the nickel wire has high purity, high conductivity ( the resistance is 7% lower than the traditional production process of wire ) and high toughness, high rate of qualified products and excellent product quality.

The processing properties: In addition to Ncu28-2.5-1 and Ncu40-2-1 soft foil, as for other nickel alloy strip, when the user needs to specify in the contract, the supplier can carry out the foil cup test.
