Nickel-copper Alloy N4
Pure nickel (N4) is a core material in many high-end manufacturing fields due to its high purity (nickel content ≥99.9%), excellent corrosion resistance, good electrical conductivity, and high-temperature stability. High purity is ensured through vacuum induction melting, and various forms of N4 products are available, such as bars, tubes, strips, wires, and plates, with a full range of specifications. Production can be carried out according to domestic and international standards.
Nickel Alloy 200
Nickel Alloy 200 is manufactured using vacuum induction melting (VIM) to ensure high purity and low gas content. Subsequent processes such as hot rolling, cold drawing, and precision grinding can produce products of various shapes and tolerances. It exhibits excellent resistance to reducing media, alkaline solutions (especially caustic soda), and numerous salt solutions; possesses high electrical conductivity and good magnetostrictive properties, making it widely applicable in the electronics field; and in sulfur-free reducing atmospheres, NI200 can be used for extended periods up to approximately 600°C, and features low gas solubility and low vapor pressure, making it suitable for aerospace components and energy applications.
Nickel Alloy 201
The core technological advantage of Nickel Alloy 201 lies in its high-purity material and extremely low carbon content design, ensuring its stability in high-temperature environments. It is used in various applications including the alkali industry (ion-exchange membrane caustic soda production), chemical equipment, food processing, electronics and electrical engineering, automotive exhaust catalysts, and aerospace. With a production capacity of 500 tons per year, the mature and stable production system can meet continuous customer demand. The product is available in various forms including plates, tubes, rods, wires, strips, and foils, with diverse specifications to meet the customized needs of customers in different industries.

III. N07750 High-Temperature Alloy Machining Properties:

Hot deformation range is 950-1205 degrees Celsius, with large deformation at 1040 degrees Celsius. Cold working properties are relatively easy to harden, so timely solution treatment is necessary to prevent cold working cracking.

IV. N07750 High-Temperature Alloy Processing:

The solution heat treatment process for plates, strips, and tubes in their supplied state is 980℃±15℃, air cooling. For intermediate heat treatment of materials and parts, the following processes can be selected: Annealing: 955～1010℃, water cooling. Annealing before welding of welded parts: 980℃, 1h. Stress-relief annealing of welded parts: 900℃, wet annealing for 2h. Stress-relief annealing: 885℃±15℃, 24h, air cooling.

V. N07750 High-Temperature Alloy Application Areas:

N07750 high-temperature alloy is mainly used to manufacture corrosion-resistant flat wave springs, circumferential helical springs, helical compression springs, spring retainers, and sealing rings for aero-engines operating at temperatures below 540℃.
