Spring wire diameter choices
This non-alloy carbon spring wire offers ten diameters: 1, 1.2, 1.5, 1.8, 2, 2.5, 3, 5, 8 and 10mm. JIS G3522, SWP-A, SWP-B and SW-C are named material or standard references. Specify the exact class and applicable standard needed by the spring drawing rather than treating the references as interchangeable.
Agree the required temper, surface cleanliness and dimensional acceptance for the selected wire. The descriptive 0.20–12.50mm span does not create extra fixed options. Smooth, oil-free, crack-free or joint-free wording should be supported by inspection requirements for the actual supply. No numeric tensile strength, fatigue result, acoustic performance or finished spring load rating is supplied. Bending and welding services do not independently establish qualified performance for every class and diameter.
