AMETEK SMP Pure Nickel Strip has been the premier material for battery connections for decades. The high purity of our material offers the highest conductivity of commercially manufactured nickel products due to the low impurity level. These non-metallic inclusions are impurities that are imparted to cast products as a result of hot rolling slabs in an unprotected environment. AMETEK maintains a low temperature cold rolling process to minimize the impurities from forming. As discussed in our Ultra Power Technical Bulletin the conductivity of our Nickel Strip is 15-20% higher than competitive materials. This higher conductivity allows for manufacturers and designers to continue miniaturizing the sizes of the battery connections without sacrificing power handling capabilities.
