Dia 5mm Pure Nickel Rod

Pure Nickel rods are solid rod-shaped metal materials made from pure nickel or nickel alloys through processes such as forging, rolling, and drawing. They are one of the most widely used profiles among nickel-based materials. Their properties can be optimized through composition control and heat treatment processes to meet the stringent requirements of various fields such as chemical engineering, electronics, and aerospace.

Dia 5mm pure nickel rod, with their high purity, excellent corrosion resistance, stable conductivity, and ferromagnetic properties, combined with their "small diameter" structural advantage, have precise and irreplaceable applications in multiple fields.

According to size specifications:

• Small nickel bars: Diameter typically 0.004mm~15mm, length 500mm~6000mm, primarily used for precision and miniaturized applications, such as electronic components and medical microelectrodes.
• Regular nickel bars: Diameter 15mm~150mm, suitable for machining mechanical parts and chemical equipment components.
• Coarse nickel bars: Diameter >150mm, mostly used as forging blanks for manufacturing core structural components of large equipment.

According to manufacturing process:

• Forged nickel bars: Forged at high temperatures, resulting in dense internal grains and excellent mechanical properties, suitable for high-load conditions.
• Rolled nickel bars: Processed by rolling mills, offering high dimensional accuracy and a smooth surface finish, suitable for mass production.
• Cold-drawn nickel bars: Drawn at room temperature, significantly improving strength and reducing surface roughness, allowing direct use in precision parts machining.

1. Corrosion resistance: It exhibits extremely high stability in neutral and alkaline media (such as seawater and caustic soda solution); it has good resistance to organic acids (such as acetic acid and citric acid); however, it is easily corroded in strong oxidizing acids (such as concentrated nitric acid).
2. Electrical and thermal conductivity: Its electrical conductivity is approximately 22% that of copper, but it maintains stable performance within a temperature range of -200℃ to 600℃; its thermal conductivity is moderate, making it suitable for applications requiring balanced heat conduction.
3. Mechanical properties: Annealed pure nickel bars have a tensile strength of approximately 345 MPa and an elongation of ≥40%; after cold drawing, the tensile strength can be increased to over 550 MPa, while the toughness decreases slightly.
4. Magnetic properties: It exhibits ferromagnetism below 340℃ (Curie temperature), but loses its magnetism above this temperature, making it suitable for manufacturing magnetic devices.
5. Biocompatibility: Pure nickel has low irritation to human tissues and can be used in basic components of medical devices.

The production of pure nickel rods requires multiple rigorous processes to ensure dimensional accuracy and performance stability. A typical process is as follows:

1. Raw Material Preparation: High-purity nickel ingots or nickel alloy ingots are selected, and surface oxide scale and impurities are removed to ensure raw material purity.
2. Heating and Forging: The raw material is heated to 1000℃~1200℃ and forged into a coarse bar shape using a forging press to refine the grain and eliminate internal defects.
3. Rolling/Drawing: The forged bar is rolled to the target diameter using a rolling mill, or cold-drawn using a cold-drawing die to improve dimensional accuracy and surface quality.
4. Heat Treatment: Annealing and solution treatment are performed as needed to eliminate processing stress and adjust mechanical properties (e.g., annealing improves toughness, and solution treatment improves high-temperature strength).
5. Finishing: Processes such as turning, grinding, and polishing further improve surface finish and dimensional tolerances to meet the requirements of precision applications.
6. Quality Inspection: Chemical composition analysis, mechanical property testing, dimensional accuracy inspection, and corrosion resistance testing are conducted. After passing these tests, the bar is packaged and shipped.
