BU013

Material 0.15mm Stainless Steel

Size 18 coils of 4mm, 2 half end coils at right angles

These Isochron springs are made to the original design but are made from Stainless steel instead of Invar or C902. They are a cheaper and more robust alternative. They are exactly the same size as BU004., but will not perform the  temperature compensating to the same high degree.

Each is supplied in a clear perspex box.

Please read the Isochron story for further information.
