The application properties of nickel and nickel base alloy
Nickel is mainly used in electroplating industry, nickel plated articles are beautiful, clean, and not easy to rust. Nickel powder is very fine, which is used as a catalyst in the chemical industry.
A large number of nickel is used for the manufacturing of alloy. Adding the nickel into steel can improve the mechanical strength. For example, the nickel content in steel increases from 2.94% to 7.04%, the tensile strength increases from 52.2 kg / mm 2 to 72.8 kg / mm 3. Nickel steel is used to make the machine parts, which can bear the big pressure, impact and load, such as turbine blades, crankshaft, connecting rod and so on. The nickel steel with 36% nickel and 0.3-0.5% carbon has small coefficient, which is used in the manufacture of various precision machinery. The high nickel steel with 46% nickel and 0.15% carbon is called "Platinum", because its expansion coefficient is similar to that of platinum and glass, this high nickel steel can be welded to the glass. It is important in the bulb production, which can be used as a substitute for platinum wire.
Titanium nickel alloy has "memory" ability, and memory is very strong, after quite a long time, it also is accurate. It's "memory" is the ability to remember its original shape, so people call it "shape memory alloy". This alloy has a transition temperature, above the transition temperature, it has an organizational structure, and below the transition temperature, it is another kind of organizational structure. The structure is different, the performance is also different.
The nickel is magnetic, which can be attracted by magnets. The alloy made of aluminum, cobalt and nickel has stronger magnetic. In this way, it can be used to manufacture the electromagnetic crane.
