Physical properties: Pure nickel wire has good ductility and plasticity and can be easily drawn into filaments. Its diameter can be very small, ranging from a few microns to a few millimeters.
Chemical properties: Pure nickel wire has good corrosion resistance to most common chemicals. It has good stability to water, air and most acids at room temperature. However, under high temperature and strong oxidizing conditions, pure nickel wire may undergo oxidation reactions.
Thermal properties: Pure nickel wire has a high melting point (about 1455 degrees Celsius) and a low linear expansion coefficient. This makes pure nickel wire have good stability and heat resistance in high temperature environments.
Application areas: Pure nickel wire is widely used in many fields. It is often used as a material for resistance wires, heating wires and heating elements. Pure nickel wire is also widely used in the chemical industry, electronics industry, aerospace and medical fields.

The thermal expansion coefficient of pure nickel wire may be somewhat different compared to other materials. The coefficient of thermal expansion is a material property that describes the rate of dimensional change of a material as a result of temperature changes.
Pure nickel generally has a higher coefficient of thermal expansion relative to other common engineering materials such as steel, aluminum and copper. This means that under the same temperature change conditions, the length or volume change rate of pure nickel wire may be higher.
Specifically, the following is the approximate range of the thermal expansion coefficient of some common materials (taking the linear expansion coefficient as an example, the unit is 10^-6/℃):
Pure Nickel: 13.3 - 14.3
Steel: 10 - 13
Aluminum: 22 - 24
Copper: 16 - 18
It can be seen that pure nickel has a higher thermal expansion coefficient compared to steel and copper. This means that under the same temperature change, the length change rate of pure nickel wire may be greater, so more attention needs to be paid to the impact of thermal expansion when applied in high temperature environments.
