Manufacturing process

The manufacturing process of pure nickel wire in the aerospace industry typically includes the following steps:

Material preparation: Select high-purity metallic nickel as raw material. The purity of nickel is usually required to be above 99.5% to ensure the quality of the final product.

Smelting and Preparation: Put high-purity nickel raw materials into the furnace for melting. Molten nickel is drawn into filaments from the molten metal through specific production processes, such as horizontal drawing, vertical drawing or jet drawing.

Cold drawing: The preliminary pure nickel wire produced by melting is drawn through a series of cold drawing processes. The purpose of cold drawing is to improve the mechanical properties and dimensional accuracy of pure nickel wire through continuous stretching. The process typically involves multiple passes of drawing, each of which gradually reduces the diameter of the filament while increasing its strength and ductility.

Annealing: Cold drawn pure nickel wire needs to be annealed to eliminate internal stress and restore its grain structure. During the annealing process, pure nickel wire is heated to a specific temperature and then slowly cooled to achieve structural stability and optimization of mechanical properties.

Surface Treatment: To meet the high requirements of the aerospace industry for pure nickel wire, surface treatment may be required. This includes steps such as surface oxide removal, cleaning and polishing to ensure the surface finish and purity of pure nickel wire.

Inspection and quality control: At all stages of the manufacturing process, pure nickel wire is subject to strict inspection and quality control to ensure that the product meets the specified technical requirements and standards. This includes dimensional measurements, mechanical property testing, chemical composition analysis, etc.

Packaging and Delivery: Quality inspected pure nickel wire is packed and ready for delivery to customers in the aerospace industry. Packaging is usually protected against moisture, oxidation, and damage to ensure that its quality and performance are maintained during transportation and use.

It should be noted that the manufacturing process of pure nickel wire may vary depending on specific product needs, specifications and suppliers, and the above steps are for general reference only. In the actual manufacturing process, there may be other specific processes and processing steps to meet the high requirements of the aerospace industry for pure nickel wire.
