详细报告
## Background
Implantable devices like pacemakers require leads that are highly conductive but absolutely resistant to body fluids.
## The Challenge
Pure copper corrodes in the body. Pure nickel is resistant but has higher resistance. Alloys often compromise on one or the other.
## The Solution
Raytron Nickel Clad Copper (NCC) wire (27% Nickel).
- **Barrier**: The outer nickel layer forms a perfect barrier against the environment.
- **Core**: The copper core carries the signal with minimal resistance.
- **Process**: Our Clad & Weld process ensures no pinholes in the nickel layer.
## Results
- **Longevity**: Simulated 10-year life successfully.
- **Biocompatibility**: Passed ISO 10993 tests.
- **Manufacturing**: Excellent drawability for ultra-fine wire production (down to 0.05mm).
