| ign="center"> | | | | high-carbon nickel steel, called "Platinum Class" |
| Nickel oxide with ferromagnetic metals, it can be | | | | because of its expansion coefficient and platinum, |
| highly polished and corrosion resistant. Mainly used | | | | the glass is similar to the high-nickel steel can be |
| in alloys (such as nickel steel and nickel silver) and | | | | welded to the glass. Production is important in the |
| used as a catalyst (such as pull-in nickel, especially | | | | light bulb can be used as a substitute for platinum |
| as a hydrogenation catalyst), used to make | | | | wire. Through the frame of some precision, but |
| money, etc., can be plated on other metals to | | | | also to do with this class of platinum steel, lens, |
| prevent rust. | | | | thermal expansion and contraction will not fall |
| Large number used in the manufacture of nickel | | | | from the box. By the 67.5% Ni, 16% iron, 15% |
| alloys. In the steel containing nickel, can improve | | | | chromium, 1.5% Mn alloy composition, with great |
| the mechanical strength. Such as the nickel | | | | resistance, used to make all kinds of varistors |
| content in steel increased from 2.94% 7.04%, the | | | | with electric heaters. |
| tensile strength will be from the 52.2 kg / mm 2 | | | | Nickel oxide are magnetic, can be a magnet to |
| to 72.8 kg / mm 3. Nickel steel used to make | | | | attract. And aluminum, cobalt and nickel alloy |
| machines to take greater pressure to bear part | | | | made of magnetic stronger. This alloy is attracted |
| of load impact and reciprocating parts, such as | | | | by the magnet, not only that they will be smoking |
| turbine blades, crank, connecting rod and so on. | | | | in the past, and it hung below its weight six times |
| 36% nickel, 0.3-0.5% nickel carbon steel, and its | | | | higher than what would not fall. In this way, you |
| expansion coefficient is very small, almost no | | | | can use it to create electromagnetic crane. |
| thermal expansion and contraction, used to | | | | Nickel salts are mostly green. Nickel hydroxide is a |
| produce a variety of precision machinery, | | | | brown-black, nickel oxide is gray black. Nickel oxide |
| precision gauges and so on. 46% nickel, 0.15% of | | | | used to produce iron-nickel alkaline batteries. |
