Product characteristic

In terms of physical properties, high purity nickel round bars are silvery white and shiny. Its density is about 8.9g/cm³ and its melting point is around 1450℃. Nickel bars have good electrical and thermal conductivity, which makes them widely used in the electronic and electrical fields. At the same time, its corrosion resistance is excellent and it can remain stable in many chemical media, especially in alkaline environments.

In terms of mechanical processing performance, nickel bars have good plasticity and forgeability, and can be made into products of different shapes and sizes through various processing techniques to meet various industrial needs. For example, it can be processed into parts in precision instrument structures, and can also be used to manufacture corrosion-resistant components in chemical equipment.

In addition, nickel bars have good thermal stability and can maintain stable performance within a certain temperature range. However, compared with some high-strength alloys, the strength of pure nickel rods is relatively low, but this does not affect its important position and wide application in specific fields.

Chemical properties:

Nickel bars have excellent corrosion resistance and can resist the erosion of various media such as acids, alkalis, and salts, especially in alkaline environments.

Product application

Nickel round bars are widely used in multiple fields due to their excellent performance:

- Chemical equipment: used for reactor linings and evaporator heating tubes of alkali-making equipment, resistant to high-temperature alkali corrosion
- Nuclear energy facilities: used as guide tube materials for control rods of nuclear reactors, meeting the requirements of neutron absorption rate
- Aerospace: manufacturing fuel nozzles for aviation engines
- Electronic industry: processing high-purity nickel target substrates, with impurity content ≤ 0.01%.
