Copper Round Rod With Mill Certificate 2mm-250mm Cold-Drawn Non-Magnetic
Cold-Drawn Non-Magnetic Copper Round Rods are precision-engineered for industries requiring zero magnetic interference, high conductivity, and certified material traceability. Manufactured from C10100 oxygen-free copper (99.99% purity) with diameters from 2mm to 250mm, these rods are ideal for MRI components, semiconductor equipment, and aerospace systems. Each rod includes a mill certificate (EN 10204 3.1) verifying compliance with ASTM B170, EN 13600, and ISO 1337 standards, ensuring reliability for sensitive applications.
Key Advantages:
- Non-Magnetic Properties: Permeability <1.001 μH/m for MRI and quantum computing applications.
- Ultra-Pure Material: Cu ≥99.99%, O ≤0.001%, Fe ≤0.003% for minimal electrical resistance.
- Cold-Drawn Precision: Diameter tolerance ±0.01mm (≤50mm) to ±0.05mm (≥50mm).
- Certified Quality: Mill certificates ensure batch traceability and chemical/mechanical compliance.
- Global Compliance: RoHS, REACH, and ISO 9001/13485 certified for medical/industrial use.
- Custom Solutions: Cut-to-length (100mm–12m), polished (Ra ≤0.2µm), or passivated surfaces.
