Applications of Ni/Cu Clad Rod Nickel-Copper Composite Rod

Production Method of Copper Nickel

Product Prep work: Select top-notch copper and nickel steels as basic materials, guaranteeing they satisfy the defined pureness and structure needs. Thawing and Alloying: The copper and nickel steels are thawed together in a heater at a heat. The melting procedure is thoroughly regulated to guarantee consistent blending of the steels and to prevent contamination. Extra alloying components might be included at this phase to change the residential properties of the last alloy.

Casting: The molten copper-nickel alloy is then poured into molds to form ingots or other shapes. The cooling process is carefully managed to minimize defects and to ensure a homogeneous microstructure.

Hot Rolling and Annealing: The ingots are hot rolled to reduce their thickness and improve their mechanical properties. Annealing may be performed after rolling to relieve internal stresses and further refine the microstructure.Additional finishing processes may be conducted on the rolled copper-nickel alloy, including cutting, drilling, and surface treatment, in order to meet particular application needs

Quality Control and Testing: Throughout the production process, rigorous quality control measures are taken to ensure that the copper-nickel alloy meets the specified standards and specifications. This may include chemical composition analysis, mechanical testing, and corrosion resistance testing.
