Key Product Data

1. Cross-sectional ratio of cladding copper ranges from 15% - 30% (the standard cross-sectional ratio of cladding copper is 20%. Upon inquiry, any ratio could be made by special ordering).
2. Mass ratio of cladding copper ranges from 30% - 60% (the standard mass ratio of cladding copper is 45%).
3. Coating layer uniformity: The thinnest point > 90% of the average thickness of the cladding copper.
4. Straightness deviation ≤ 0.15%
5. Tolerance: Width ±0.3mm, thickness ±0.05mm
6. Interfacial bonding strength (shear strength) shall be great than the anti-shear strength of aluminum (50MPa ~ 80MPa under normal condition).
7. Shape: The side of the cross-section are rounded, R=1/2 thickness
8. Temper: Soft or hard
9. When bend the broad-side 90°, the cladding copper shall exhibit no crack, the cladding copper and the aluminum s core shall not separate.
10. Surface: After sanding and polishing, no visible defects
11. Shipping condition: coated with anti-oxidant protection (lifespan under normal temperature conditions is over 1 year), wrapped with thin plastic insulating film.
