What is a nickel plate?
Nickel is a ferromagnetic metal element, which can be highly polished and corrosion-resistant. Nickel plate is extracted from nickel ore by electrolysis, and its purity is generally as high as 99%-99.99%. Mainly used in alloys (such as nickel steel and nickel silver) and as catalysts (such as raney nickel, especially for hydrogenation)? , can be used to make money, etc. Plating on other metals can prevent rust.
Nickel plate specifications:
Specification of nickel plate (thickness * width * length/mm): 0.5-20 * 200-1000 * 500-3000.
Nickel plate price:
The price of nickel plates varies from place to place. Many factors such as transportation distance, supply and demand will cause the price fluctuation of nickel plate. At present, the domestic nickel plate price is generally at 120000- 123000 yuan/ton.
The purpose of nickel plating:
Nickel plates are widely used in highways, railways, civil buildings, water conservancy and other buildings; All kinds of machinery, electrical appliances, window protection, aquaculture.
One purpose of nickel plate: it is mainly used for cement batching in civil construction, protection of machinery and equipment, handicraft manufacturing and high-grade speaker net cover. Highway guardrail, stadium fence, road green belt protective net, stainless steel, electroplating, nickel-hydrogen battery, etc.
The second use of nickel plate: heavy nickel plate can be used for heavy machinery and oil tanker pedal network, working platform, escalator, walkway, etc. of boilers, oil mines, locomotives, 10,000-ton ships, etc. It can also be used for strengthening the construction industry, highways and bridges.
The third use of nickel plate: it is widely used to make alloys. Adding nickel to steel can improve mechanical strength. When the nickel content in steel increases from 2.94% to 7.04%, the tensile strength increases from 52.2 kg/mm2 to 72.8 kg/mm2.
Four uses of nickel plate: Nickel steel can be used to manufacture machine parts that bear heavy pressure, impact and reciprocating load, such as turbine blades, crankshafts and connecting rods.
Five uses of nickel plate: nickel steel containing 36% nickel and 0.3-0.5% carbon. Its expansion coefficient is very small, and it hardly expands with heat and contracts with cold. It is used to manufacture a variety of precision machinery and precision gauges.
The sixth application of nickel plating: 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, and this high-nickel steel can be welded into glass. It is very important in bulb production and can be used as a substitute for platinum wire. Some precision frames are also made of this kind of platinum-like steel, and the lenses will not fall off from the frames because of thermal expansion and cold contraction.
Usage 7: Nickel plate is an alloy composed of 67.5% nickel, 16% iron, 15% chromium and 1.5% manganese. It has great resistance and is used to manufacture various varistors and electric heaters.
Usage 8: Nickel plate 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 alloy with high nickel content is not easy to corrode. It is also used as a hydrogenation catalyst and in the preparation of ceramic products, special chemical utensils, electronic circuits, green glass and nickel compounds.
