Micro Shield, an alternative to stainless steel shielding, was engineered specifically for high strength coaxial shielding applications. It is a copper-nickel-tin alloy processed for both high strength and long flex life. 

Key Attributes of Micro Shield

  • Strong with tensile strengths in excess of 150,000 psi (1030 MPa or 105 kg/mm squared).
  • Highly solderable
  • Excellent resistance to corrosive environments.
  • Has identical chemical, mechanical and electrical properties to CS-95.

Micro Shield is available bare or electroplated with nickel, silver or tin. And, in ultra-find gauges as single end wires or as multiple wire bobbins.
