Description

Ni200 is made of pure Nickel and has an extremely high temperature coefficient. Nickel wire is very soft and springy, making it more difficult to work with when compared to Kanthal or Titanium. When wrapping Nickel, it’s a good idea to space the wraps apart so the heat is evenly distributed throughout the length of the wire. If there are any wraps in the coil that are touching each other, you’ve created a potential hotspot that can cause the coil to short. Because of this, many people have started twisting the wire before they make their coil. This allows for equal heat distribution (if done correctly) with tight wraps; however, it can be time consuming. For this reason some people consider Ni200 to be problematic, whereas other people swear by it to be the best metal for Temperature Control devices.
