Frequently Asked Questions

Copper-coated fiber reaches a higher maximum temperature (+600°C short-term, up to +400°C continuous) versus aluminum-coated fiber's +400°C, and uses an additional carbon underlayer to improve coating hermeticity and mechanical strength.

A thin carbon layer beneath the copper coating improves the hermetic seal and further increases mechanical strength compared to copper coating alone.

Yes — the solderable metal coating allows the fiber to be fed into high-vacuum systems without outgassing, unlike polymer-coated fiber.
