This Spring Wire, also known as Piano Wire, is made from precision-drawn high-carbon steel for strength, resilience, and durability. The nominal diameter for 20 SWG is 0.914 mm, with a small manufacturing tolerance, so it is commonly referred to as 0.9 mm wire.
The wire offers excellent rigidity and consistent roundness, making it suitable for a wide range of uses, including RC aircraft control rods, linkages, springs, and general workshop projects where durable tension or structural support is required.
Supplied in a straight 5-meter length, this size is practical for medium-duty constructions and detailed engineering work.
