1. The significant difference between pure nickel and nickel-plated steel is the ability of corrosion resistance and electrical conductivity. Most users choose the first method, such as placing a scratched nickel sheet in a corrosive liquid.
2. The hardness of pure nickel is controllable in the annealed process. Pure nickel can be very hard or very soft, so the hardness cannot be used as a basis for distinguishing whether strips are pure or not. All the 0.15mm and 0.2mm pure nickel strips from Shonan.Systems are a little softer than 0.1mm so that users can better spot welding the strips to batteries.
3. Whether nickel strips are easy to weld is affected by many factors, such as the surface of the nickel strip, the material of battery poles, and the power settings of your welding tool. When spot welding thicker nickel strips (thickness ≥ 0.15 mm), to make reliable spots, please increase the power settings of your battery welding tool.
4. For different batteries, the materials of poles will be different, most of them are made of stainless steel, iron-plated nickel and iron. In terms of the degree of weldability, stainless steel > iron-plated nickel > iron, which means a 0.15 mm pure nickel sheet can be welded to a battery’s pole made of stainless steel easier than a pole made of iron.
