General characteristics

Sheet NP-2 is made from nickel of 99.5% purity. This grayish-yellow metal was discovered at the end of the 18th century and was nicknamed after the harmful dwarf Nick. And for good reason. Although nickel ore is almost the same as copper ore, no one has ever been able to smelt a drop of metal from it. Pure nickel is a very hard, malleable metal. It retains its magnetic properties at temperatures up to +300°C. Ni became the base of superalloys - heat-resistant steels that are used everywhere from aerospace equipment to medical instruments and kitchenware.

Chemical composition (GOST 492 - 2006)

Impurities

The properties of nickel sheets depend on the impurities. Sulfur, antimony, zinc, bismuth and lead impair nickel characteristics. Sulfur forms a sulfide film on the sheet surface that melts at low temperatures and makes the sheet brittle. The main method of removing the sulfide film is electrorefining. To do this, the sheet is placed in an electrolyte, and another nickel sheet serves as a cathode on which the chemically pure metal is deposited. During NP-2 purification the sheet generates so called anodic sludge, which can be easily broken down into valuable chemical components that pay for the total cost of the purification procedure.

Mechanical properties

Application

NP-2 alloys are used to produce anodes and cathodes in accordance with GOST 2132-90 and technical specifications. NP-2 sheets are used in mechanical engineering and instrument making. Such sheets can be added to the charge to enrich the melt with nickel. NP-2 sheet is widely used for production of accumulators, coin minting. Widespread electroplating of nickel on products, for which the sheet NP-2 is also used. Nickel coating almost does not oxidize and can protect parts from corrosion for a long time. Air, water, many alkalis and acids do not affect its condition.

Supplies

Parameters: 5 to 20 mm thick, 500 to 800 mm wide and 500 to 2,000 mm long. Allowable deviation from length ±20 mm. Sheets NP-2 are made according to GOST 492-73 and can be measured, unmeasured length, multiple of measured.
