0.5mm Spring Wire / Piano Wire – 5m Length

This Spring Wire, also referred to as Piano Wire, is made from precision-drawn high-carbon steel for strength, resilience, and durability. At 25 SWG, the nominal diameter is 0.508 mm. As with all drawn wire, a small manufacturing tolerance applies, so the actual diameter may measure slightly above or below the stated size.

This tolerance is the reason it is commonly referred to as “approximately 0.5 mm.” The wire maintains consistent roundness and strength, making it ideal for applications that require fine structural support or spring tension.

Common uses include hobby and model making, RC aircraft control rods, linkages, and general workshop projects.

Supplied in a 5-meter length, this size is especially practical for lightweight constructions and detailed engineering tasks.

Includes:

• 1 × 5m length of 25 SWG (≈0.5mm) Spring Wire / Piano Wire on the Coil
