• Hardness: Depending on the processing technology and treatment method, the nickel strip can present different hardness states, such as soft (M), semi-hard (Y2), hard (Y), etc., to adapt to different use scenarios.
3. Chemical properties:
• Corrosion resistance: Nickel itself has excellent antioxidant properties, at room temperature, nickel in seawater, salt solutions and organic media (such as fatty acids, phenols, alcohols, etc.) is extremely stable, especially resistant to alkali corrosion, in high temperature or molten alkali is also relatively stable, but not resistant to inorganic acid corrosion, in acetic acid and formic acid stability is poor.
• Magnetic properties: It has certain magnetic properties and is a transition metal.In some applications that require the use of magnetism, such as electromagnetic equipment, magnetic sensors, etc., nickel strips can play a role in its magnetic properties.
4. Electrical characteristics:
• Electrical conductivity: It is a good conductive material, although its electrical conductivity is not as good as copper, silver and other metals, but in some occasions with high electrical conductivity requirements, such as battery connectors, electronic components, nickel strip can still meet the demand, and its electrical conductivity is stable, not easily affected by external factors.
5. Processing characteristics:
• Weldability: It has good weldability and can be connected with other metal materials by welding and other means to form a strong structure, which is convenient for assembly and connection in the manufacturing process.
• Machinability: It can be processed by a variety of processing methods, such as cutting, stamping, drilling, etc., and can be processed into products of various shapes and sizes according to the specific requirements of use to meet the needs of different application scenarios.
Product Description

 

The main uses of nickel strip are as follows:
