Recently GNEE has successfully delivered a batch of 400 kg of high quality FILO RAME 0.071 F D.S. 155℃ G2 tinned copper wire to a leading Italian manufacturer under a long term on time supply contract.
Technical Deep Dive: Understanding FILO RAME 0.071 F D.S. 155℃ G2 Specifications
This specialized copper wire represents the pinnacle of precision engineering for critical electronic applications. Let's decode its technical nomenclature:
Base conductor: Oxygen-free copper (Cu-OF) with 99.99% purity
Coating: Dual-layer tin plating (Sn99.9%)
0.071mm nominal diameter (±0.002mm tolerance)
Consistent circularity (<=1% ovality)
: Annealed soft temper (conductivity >=101% IACS)
D.S. coating: 2-3μm per side tin thickness (meeting IEC 60851-5)
155℃ rating: Continuous operation temperature (3000hrs lifespan)
G2 grade: Passes EN 13602:2013 salt spray test (96hrs)
Complies with EU RoHS 3 and REACH regulations
1. Micro-Tolerance Manufacturing
