Oxidized Battery Cold Rolled Nickel 200 Pure Nickel Strip

Nickel 200 min 99% Purity Nickel Strip for Battery Building Application

1.Product Description

Ni 200 is a 99.6% pure wrought nickel alloy. Sold under the brand names Nickel Alloy Ni-200, Commercially Pure Nickel, and Low Alloy Nickel, Ni 200 offers users a wide range of benefits including its primary component, nickel. Nickel is one of the world’s toughest metals and imparts a number of advantages to this material. Ni 200 has excellent resistance to most corrosive and caustic environments, media, alkalis, and acids (sulfuric, hydrochloric, hydrofluoric). Used both indoors and outdoors, Ni 200 also has:

The surface of the pure nickel strip should be smooth and clean without wind layers, cracks, bubbles, spikes, bends and inclusions. Minor local defects, such as scratches, spots, pits, dents, roll marks, etc., that do not exceed the allowable deviation of the strip thickness are allowed. Slight oxidation, blackening, and slight local oil marks are not used as the basis for scrapping. Cut strips on both sides without burrs, cracks, or curls. The strip should be straight, but slight waves are allowed; the lateral bend of the strip should not exceed 3 mm per meter.

Pure nickel belts show good corrosion resistance in many acidic and alkaline environments and are mainly used in reducing media. It has good mechanical properties in a relatively wide temperature range and is easy to cold work. Therefore, it is widely used in plate heat exchangers, bellows compensation expansion joints, caustic soda, chemical equipment, etc. However, in the actual production of pure nickel strip, as with titanium strip coils, there are also many technical difficulties in the annealing of the entire strip of nickel strips. If the annealing temperature is too high and the holding time is too long, the entire nickel belt roll is easily annealed and bonded, but if the holding time is not enough, the entire roll cannot be retracted. Therefore, low temperature and long time annealing is an effective way to reduce the overall coil annealing of nickel strip steel.
