Nickel Cards

The nickel card is the result of cutting nickel cathode sheets. The cutting operation is carried out to increase the speed of the loading / unloading process, as well as to more accurately meet the needs of the customer. A nickel card is used as one of the main components of modern superalloys – heat-resistant materials used in aerospace for parts of power plants. Nickel superalloys are also white gold, used in a variety of jewelry, monel metal, nichrome, as well as nickel and chromium-nickel steels. The use of nickel in these metals significantly increases their corrosion resistance. It is interesting that alloys of some metals with nickel have the so-called “shape memory” effect. In practice, this means that if the original shape given to the product was broken, it can be restored by heating. For example, a titanium nickelide connecting pipe, which is widely used in military aircraft hydraulic systems: first, the pipe is set to the desired shape and projections for fixing, then it is cooled to −196 ° C, smoothing out all irregularities and making it perfectly smooth inside. Then the tube is put on 2 connected pipes and at room temperature it restores its original fixing protrusions. In a “regular” fighter, the number of such compounds is from 300 thousand and higher. However, due to the high strength of the alloy itself, there have never been reports of failures of such compounds.
