What is TP1/C12000 copper?
The C12000 Copper Plate, classified as low-phosphorus deoxidized copper (DLP), stands as a premier material for applications demanding superior electrical and thermal performance. This high-purity Copper Plate minimizes oxygen content to prevent hydrogen embrittlement, ensuring reliability in critical environments like aerospace, power generation, and electronics manufacturing. Its unique properties bridge industrial durability with precision machining versatility.

C12000 Chemical Composition
The C12000 alloy features rigorously controlled chemistry: ≥99.95% copper (Cu) maximizes conductivity, while trace phosphorus (0.003–0.005%) acts as a deoxidizer. Oxygen content is capped at ≤0.003% – significantly lower than standard copper plates – eliminating porosity risks during welding. Impurities (Pb, Fe, Sb) are restricted to ≤0.02%, ensuring corrosion resistance and structural integrity. This composition makes C12000 Copper Plate ideal for high-reliability applications where purity dictates performance.
C12000 Exceptional Physical & Mechanical Properties
Engineered for excellence, the C12000 Copper Plate achieves ≥100% IACS electrical conductivity – the highest among commercial copper alloys. Its thermal conductivity (390 W/m·K) enables efficient heat dissipation in thermal management systems. Mechanically, it balances tensile strength (220–270 MPa) with exceptional elongation (up to 45%), supporting complex cold-forming operations like deep drawing and stamping. The Copper Plate's hydrogen-embrittlement resistance ensures stability in reducing atmospheres, while its fine-grained structure guarantees precision in EDM electrode applications.
Diverse Industrial Applications
This C12000 Copper Plate excels across critical sectors:
Electrical Systems: Busbars, transformer windings, and circuit breakers leverage its unmatched conductivity.
Thermal Management: Heat exchangers, condenser tubes, and solar thermal collectors utilize its heat-transfer efficiency.
Automotive & Defense: Brake lines, ammunition components, and naval fittings benefit from its vibration resistance.
Precision Fabrication: EDM electrodes, semiconductor fixtures, and photovoltaics rely on its machining consistency.
The C12000 grade outperforms alternatives like C11000 in high-stress, high-corrosion environments.
