Copper forgings have significant advantages in multiple fields due to their combination of material properties and forging processes. The following is a detailed analysis of its main advantages:

1. Excellent mechanical performance

High strength and toughness: Forging refines the grain structure of copper through high-temperature and high-pressure processing, eliminates casting defects such as porosity and shrinkage, significantly improves tensile strength, hardness, and fatigue resistance, while maintaining good toughness, suitable for withstanding dynamic loads.

Impact resistance: Forged copper parts perform more reliably in impact or vibration environments, such as ship components and mechanical connectors.

2. Excellent conductivity and thermal conductivity

Conductivity: Pure copper has conductivity second only to silver. After forging, its density increases and its conductivity efficiency is better than that of cast or powder metallurgy copper parts. It is widely used in electrical connectors and switch components.

Thermal conductivity: Its efficient heat dissipation capability makes it an ideal material for radiators and heat exchangers (such as electronic device cooling systems).

3. Corrosion resistance

Anti environmental erosion: Copper is naturally resistant to atmospheric, seawater, and most chemical media corrosion. Forging reduces internal pores and further blocks the penetration of corrosive media, making it suitable for harsh environments such as marine engineering and chemical pipelines.

Long lifespan: No need for frequent replacement, reducing maintenance costs (such as ship accessories, seawater desalination equipment).

4. High precision and complex forming capability

Near net forming: The forging process can produce workpieces that are close to the final shape, reducing the amount of subsequent processing and saving materials and time.

Complex structure: Achieving complex geometric shapes (such as valves and gears) through mold design to meet the requirements of precision equipment.

5. Economy and environmental friendliness

High material utilization rate: Forging reduces waste, especially suitable for high cost copper materials, reducing production costs.

Recyclability: Copper can be 100% recycled, meeting the requirements of sustainable development and reducing resource waste.

6. Wear resistance and self-lubricating properties

Low friction coefficient: Copper alloy (such as tin bronze) forgings have self-lubricating properties, suitable for friction components such as bearings and sliders, reducing wear and extending service life.

Typical application scenarios

Electrical and electronic: high voltage switch contacts, busbar connectors.

Industrial equipment: pumps and valves, gears, hydraulic components.

Automotive field: bearing bushings, heat dissipation components.

Architecture and ships: corrosion-resistant pipelines, marine hardware.

Advantages compared to other processes

VS Casting: Higher strength, fewer defects; Suitable for high reliability scenarios.

VS machining: saving materials, especially more economical for complex parts.

summarize

Copper forgings have become the preferred choice in high demand industrial fields due to their high strength, electrical/thermal conductivity, corrosion resistance, and process flexibility. Although the initial cost may be high, its long lifespan and low maintenance cost are more cost-effective in long-term use.
