II. Multiple applications

1. Power field

It can be used to manufacture conductors for ultra-high voltage transmission lines. Compared with traditional materials, conductors made of GK-CUL45 copper alloy rods can significantly reduce line losses, improve transmission efficiency, and ensure stable power transmission. At the same time, its good mechanical properties can also adapt to complex natural environments and reduce line failures caused by bad weather.

2. Electronic information industry

GK-CUL45 copper alloy rods can be used as ideal materials for high-end chip pins, electronic component connection wires, etc. Its high conductivity can effectively reduce signal transmission delays and improve the operating speed and stability of electronic equipment; high hardness and corrosion resistance can ensure the reliability of electronic components during long-term use.

3. Aerospace field

Lightweight and high strength are key considerations for material selection. The density of GK-CUL45 copper alloy rods is about 5% lower than that of traditional copper alloys. While achieving lightweight, it maintains high strength. It can be used to manufacture aircraft engine components, aircraft structural parts, etc., which helps to improve the performance and fuel efficiency of aircraft and provide strong support for the development of aerospace industry.

III. Precautions

1. Storage requirements

Store in a dry environment with a temperature of 5-35℃ and a humidity of ≤45% RH, and avoid storage with acidic and alkaline substances;

2. Transportation specifications

Use wooden/rubber supports to prevent rolling, and use shockproof foam to wrap the rods with a diameter of ＜20mm to prevent vibration, and avoid collision deformation and surface damage throughout the process.

3. Application in corrosive environments

When used in marine engineering or industrial atmospheric environments, it is recommended to electroplate a 5-8μm nickel layer on the surface of the alloy rod, or spray an epoxy resin or other corrosion-resistant coating to improve corrosion resistance. For parts that are in long-term contact with seawater or chloride ion solutions, zinc alloy sacrificial anodes can be installed, and cathodic protection can be performed at a current density of 0.01-0.03A/㎡.

4. Recycling and reuse

When recycling GK-CUL45 copper alloy rods, they must be strictly classified to prevent mixing with other copper alloys. During the regeneration smelting, the temperature is controlled at 750-800℃ to avoid the volatilization of boron elements; the cutting waste can be processed by the "mechanical crushing - magnetic separation - vacuum melting" process. Recycled materials are suitable for the manufacture of low-performance structural parts. If used in high-end fields, it is recommended to add 5%-10% new materials to stabilize the performance.

IV. Conclusion

The advent of GK-CUL45 copper alloy rods marks a major breakthrough in the field of high-end copper alloy materials, which is expected to reshape the industry landscape and lead a new round of industrial transformation. As its application scope continues to expand, we have reason to expect it to play a key role in more fields and inject new vitality into promoting high-quality economic and social development.
