Advantages of TiNi Alloy
NiTi has the ability to "remember," and has a strong memory, and over a long period of time, can accurately repeat millions of times. Its "memory" ability is to remember its original shape, so people call it "shape memory alloy". It has been proved that the alloy has a characteristic transition temperature. When the temperature is higher, it has one structure, while below it, it has another structure. Different structure, different performance.
For example, nickel titanium shape memory alloys are hard above the transition temperature, but below this temperature they are soft and easy to cold work. So when we want it to remember a shape, we can make it into that shape, its "permanent memory" shape, and below the transition temperature, because it is soft, we can deform it a lot. When you want it to return to its original shape, just heat it above the transition temperature.
Nickel is mainly used in electroplating industry. Nickel plated products are beautiful, clean and not easy to rust. A fine powder of nickel, usually used as a catalyst in the chemical industry, that is magnetic and attracted by magnets. Alloys made of aluminum, cobalt and nickel are more magnetic. The alloy, which is attracted by the electromagnet, will not only pass by itself, but also hang something six times its weight under it without falling off. So it can be used to build a crane. Nickel salts are mostly green. Nickel hydroxide is brown and black, while nickel oxide is gray and black. Nickel oxide is often used to make iron alkaline nickel batteries.
