Size range and international standards of C12000 copper plate:
Size range
Thickness: 0.3 mm to 150 mm (customization is supported).
Width: 200 mm to 3100 mm.
Length: up to 8100 mm (some data show 8000 mm or 12000 mm, which may vary slightly due to production process or customer needs).
International standards
C12000 copper plate complies with the following international standards:
ASTM (American Society for Testing and Materials):
ASTM B4152 standard clearly covers the production requirements of C12000 copper plate.
ASTM B280 standard lists C12000 as a copper tube material for air conditioning and refrigeration equipment (note that this standard is mainly for tubes).
DIN (German Industrial Standard): Applicable to copper plate manufacturing and acceptance.
EN (European Standard): EN 12735 (involving copper tube applications).
JIS (Japanese Industrial Standard): JIS H3100, H3300, etc.
GB/T (Chinese National Standard): GB/T 29094-2012 on the status of copper plates
Main ingredients:
Copper (Cu): content ≥99.90% (with other elements the sum does not exceed 0.1%).
Phosphorus (P): content ranges from 0.004% to 0.012% (some standards such as ASTM B152/B152M-2019 stipulate 0.004% to 0.035%). The role of phosphorus is deoxidation, improving weldability and corrosion resistance.
Impurity elements (extremely low content, usually not exceeding the following limits):
Lead (Pb), iron (Fe), nickel (Ni), antimony (Sb), arsenic (As), bismuth (Bi), sulfur (S), etc.: total impurity content ≤0.1%, and the content of each element alone is usually ≤0.02%.
Oxygen (O): controlled by phosphorus deoxidation process, the residual content is extremely low.
Mechanical properties:
Tensile strength (σb): ≥295 MPa (room temperature tensile properties of the strip)
Elongation (δ10): ≥3% (reflects the plasticity of the material)
Hardness:
Annealed state: about 55~80 HV (Vickers hardness)
Cold working state: up to 80~100 HV
Other properties:
Good cold bending and welding properties, suitable for pipeline forming
No tendency to "hydrogen disease", can be used in reducing atmosphere
Physical properties:
Electrical conductivity and thermal conductivity: high, but the addition of phosphorus makes it slightly lower than pure copper
Corrosion resistance: good performance in fresh water, sea water and general atmospheric environment, but susceptible to nitric acid and sulfur-containing media
Production process and product advantages of C12000 copper plate:
1. Production process
Basic processing technology: The production of C12000 copper plate mainly adopts hot rolling, cold rolling and forging processes. The specific process includes smelting, casting, milling, hot rolling, cold rolling, annealing, pickling, finishing, leveling, shearing and other steps to ensure the high precision and uniformity of the material.
Surface treatment: A variety of surface treatments can be performed according to needs, such as polishing, polishing, mirroring, sandblasting, etc., to meet the requirements of different application scenarios.
Quality control: International standards (such as ASTM, GB, etc.) are strictly implemented during the production process, and multi-stage quality inspections are performed to ensure stable product performance.
2. Product advantages
Excellent electrical and thermal conductivity: C12000 is a low-phosphorus deoxidized copper alloy, and its electrical conductivity and thermal conductivity are better than TP2 copper materials, especially suitable for applications with high electrical conductivity requirements.
Good processing performance:
It shows good plasticity and ductility in both cold and hot processing, and is easy to stamp, bend, weld and form.
Suitable for processing in reducing atmospheres, and low residual phosphorus content, further improving processing stability.
Mechanical properties and corrosion resistance:
It has high strength, toughness and wear resistance, and the bright surface further enhances corrosion resistance, making it suitable for high stress environments (such as electric vehicle battery contact points).
No tendency to "hydrogen disease", high reliability in long-term use.
Wide range of applications:
Electronics and electrical: used in cooling systems, connectors, circuit components, etc. to improve thermal management and signal stability.
Construction and home appliances: suitable for decorative materials, water and gas pipelines, heat exchangers, etc.
Transportation and energy: plays a key role in photovoltaic cells and electric vehicle charging systems.
Economic benefits: Compared with other high-performance copper alloys, C12000 has more cost advantages while maintaining comprehensive performance.
