C44300 copper plate production process and product advantages:

Production process

Raw material processing:

Copper plate production starts with raw materials (copper ingots), and then goes through pre-treatment steps such as water washing, degreasing, and cleaning to remove surface impurities.

The milling process is used to ensure that the surface of the material is flat and uniform.

Hot processing:

Hot rolling: Rolling at high temperature to form a preliminary plate, and further adjust the shape through straightening.

It is necessary to control the content of impurities (such as lead, iron, etc.) to avoid cracking during hot pressing.

Cold processing and annealing:

Cold rolling: Improve the strength and surface accuracy of the plate.

Annealing: It is carried out in the temperature range of 600-700°C to eliminate internal stress and improve processing performance. Evidence shows that the annealing time needs to be adjusted according to actual needs.

Surface treatment and finishing:

After cold rolling, pickling is required to remove the oxide layer, followed by finishing rolling (medium/fine) to improve the surface quality.

Some processes may involve painting or drying (such as primer and topcoat spraying) to enhance corrosion resistance.

Inspection and packaging:

The finished product must pass mechanical property tests (such as tensile strength, hardness) and corrosion resistance tests, and finally be packaged and stored.

Product advantages

Excellent corrosion resistance:

Contains trace amounts of arsenic (0.03-0.06%) and tin (0.8-1.3%), which can effectively inhibit dezincification corrosion, especially suitable for marine environments and corrosive media such as sulfur compounds.

Excellent mechanical properties:

Tensile strength ≥410 MPa, elongation ≥8%, Brinell hardness up to 80 HB, suitable for high-load scenarios.

Excellent cold processing performance, supporting a variety of processing methods such as casting, forging, welding, etc.

Good thermal performance and conductivity:

The thermal conductivity is 64 Btu/sq ft/ft hr/°F, with excellent conductivity, suitable for heat exchangers, electrical components, etc.

Wide range of applications:

Mainly used in marine engineering (condensers, seawater pipelines), thermal power plants (heat exchangers), ship parts and architectural decoration.

Processing flexibility:

Supports customized thickness (such as 1mm-10mm), width (20-2500mm) and hardness (soft/hard) to meet diverse needs.
