Nickel plate is mainly used for civil engineering construction of cement, mechanical equipment protection, handicraft manufacturing, high-end speaker net cover. Highway guardrails, stadium fences, road green belt protection nets.
The use of nickel sheets is used in large quantities for the manufacture of alloys. By adding nickel to the steel, the mechanical strength can be improved. If the nickel content in the steel increases from 2.94% to 7.04%, the tensile strength increases from 52.2 kg/mm2 to 72.8 kg/mm3.Nickel steel is used to make parts that are subjected to high pressure, shock and reciprocating loads, such as turbine blades, crankshafts, connecting rods, etc. Nickel steel containing 36% nickel and 0.3-0.5% carbon, its expansion coefficient is very small, almost no thermal expansion and contraction, used to manufacture a variety of precision machinery, precision gauges and so on. A high-nickel steel containing 46% nickel and 0.15% carbon is called "platinum-like" because its expansion coefficient is similar to that of platinum and glass. This high-nickel steel can be welded into glass. It is very important in the production of light bulbs and can be used as a substitute for platinum wire.
The use of nickel plates is mainly used to make stainless steel and other corrosion-resistant alloys, such as nickel steel, nickel-chromium steel and various non-ferrous metal alloys. Copper-nickel alloys with high nickel content are not easy to corrode. Also used as hydrogenation catalysts and in ceramics, special chemical vessels, electronic circuits, glass green and nickel compound preparation.
