Common Profiles
| Item | Specification / Description |
|---|---|
| Specification | (custom tooling available) |
| Flat / rectangular wire | most popular for spiral springs, brushes, reeds |
| Square wire | square circlips, locking components |
| D-shape / half-round wire | anti-slip & fitting assembly |
| Trapezoidal wire | wedge wire filter, retaining rings, piston rings |
| Triangular wire | filter mesh, engagement structures |
| Specification | Step profile, grooved, ribbed, toothed, oval and other special custom profiles |
Tempers
| Item | Specification / Description |
|---|---|
| Specification | ANN soft, 1/2H half hard, SH spring hard; carbon steel available quenched & tempered |
| Note | Austenitic stainless steel (301/302/304/316) gains strength from cold rolling only, not heat treatable. Carbon / martensitic / alloy spring steel can be quenched & tempered after profiling. |
Surface Finishes
| Item | Specification / Description |
|---|---|
| Specification | BA bright, matte dull, pickled, blued, phosphated, nickel plated, zinc plated |
Size Range
| Item | Specification / Description |
|---|---|
| Single side / thickness | 0.05～6.0 mm, tight tolerance down to ±0.003~±0.005 mm. Supplied in coils or spools. Sample development & mass production available, tooling cost applies for new profiles. |
Features
- Profile engineered to fit design; higher load capacity & anti-rotation function vs round wire in limited space
- Cold rolled forming for stable dimension; edges can be radiused to reduce stress cracking
- Lead time: simple profile 3–7 days; complex profile 7–15 days, pre-production sample available
Applications
Spiral springs, circlips, piston rings, wedge filter wire, motor brush wire, connector springs, medical device wire, wiper reeds, blade blanks, textile & automotive precision elastic parts
Material Selection Guide
Grade selection guide: High spring force → 301 / SK85 / 65Mn General corrosion resistance → 304 Chloride / salt spray environment → 316L High load & elevated temperature → 631 / 50CrVA
