Configurations

Construction options

Available construction approaches. Specify the geometry and materials your design requires.

D = d + 2t

The overall diameter D is the metal core diameter d plus twice the radial glass thickness t.

Glass-insulated microwire

A cast metal core in a glass coating for electrical and thermal insulation, mechanical protection, chemical resistance and dielectric properties. Cast on self-developed equipment.

Nanowire

Glass-insulated wire with a metal core below 1 µm.

Bare microwire

Glass removed by chemical etching for applications that need an insulation-free wire.

Sensing applications

Point electrodes on precious metals, micro–nano probes based on gold, filamentary nanostructured compositions and Wiegand sensors.

Technical detail

Product details

A metal core. A glass coating.

A fine metal core surrounded by a glass coating. Core material, metal diameter and overall diameter are specified separately.

Define the wire you need

Include the metal or alloy, target core diameter, insulation requirements and required length. State whether the wire will be wound, connected or used as a sensing element.

Check the complete specification

Ask for the available material and dimensional range for your application. Confirm electrical requirements, glass thickness, handling and termination before choosing the wire.
