Production process and product advantages of C61300 copper plate and copper strip:

1. Production process

Melting and casting process

Using submerged horizontal continuous casting technology, nitrogen protection is used to reduce metal oxidation, shorten the process flow and reduce energy consumption (such as horizontal continuous casting reduces the flow channel link to avoid cooling of molten metal).

Micro rare earth element smelting technology is applied in the casting process to improve material performance and increase the yield rate.

Rolling process

Hot rolling: large ingot rolling and thickness closed-loop control technology are used to increase rolling speed and reduce unit energy consumption.

Cold rolling: Through AGC closed-loop thickness control and roller type technology, product accuracy is ensured, and the yield rate is significantly improved.

Precision rolling equipment (such as two-roll hot rolling unit) realizes high-precision tolerance control, and the surface finish meets international standards.

Annealing and surface treatment

Using high hydrogen atmosphere expansion annealing technology, combined with low-temperature and low-tension continuous annealing process, optimizes material mechanical properties and reduces energy consumption.

Surface cleaning and degreasing passivation treatment (such as online atomization degreasing technology) reduce pollutant emissions and improve product surface quality.

Finishing and packaging

Mechanized packaging machine arrays and strip slitting technology improve the yield rate, while standardized sea transportation packaging ensures transportation safety.

2. Product advantages

Excellent mechanical properties

Tensile strength ≥ 600MPa, elongation ≥ 6%, suitable for high-strength industrial applications (such as heavy machinery, automotive parts).

It has good hot and cold processing properties and can be subjected to a variety of forming processes such as hot forging, rolling, and bending.

Corrosion resistance and durability

It performs well in harsh environments such as marine engineering and chemical equipment, and is resistant to sulfuric acid corrosion, but is not suitable for nitric acid environments.

Aluminum bronze material (containing 90% copper, 7% aluminum, and 2.7% iron) provides high wear resistance and oxidation resistance, extending the service life of the equipment.

High precision and customization

Tolerance control (such as ±0.001mm level accuracy) is achieved through digital process management to meet the high-precision requirements of electronic connectors, semiconductors, etc.

Support customized size (width 20-1500mm), surface treatment (polishing, coating, etc.) and packaging requirements.

Energy saving, environmental protection and economy

The comprehensive yield rate is 10% higher than that of traditional processes, and the unit energy consumption is reduced by more than 20%.

Flexible payment terms (30% advance payment + 70% final payment) and 7-25 days fast delivery cycle to optimize customer supply chain management.

Wide application

Covering automotive electronics, 5G communications, condenser tubes, marine composite panels and other fields, especially suitable for high value-added products such as bolts and corrosion-resistant containers.
