82A/82B Spring Wire for Consistent Spring Coiling
Spring performance depends on wire tensile range, diameter tolerance and straightness, because these determine coil diameter, spring rate and the stability of automatic coiling machines. This spring wire is supplied in 82A and 82B grades, with diameters selectable within the 0.15-12mm range.
Wire is cold drawn and can be supplied in bright or oiled condition. Tensile range is confirmed per diameter and coil weight so that the spring set matches the design requirement. Diameter and straightness are inspected before packing, since small deviations repeat across every coil formed from that wire.

Applications
Mattress and Furniture Springs
Spring wire for mattress units and furniture springs, where consistent tensile and coil behavior affect comfort and durability.
Compression and Extension Springs
Wire for compression springs, extension springs and torsion springs produced on automatic coiling equipment.
Clips and Retaining Parts
Formed wire parts such as clips, retaining rings and snap parts requiring predictable spring-back.
General Wire Forming
Bending and forming of spring-type wire components for industrial and consumer products.
Product Advantages
- Controlled tensile range - tensile is confirmed per diameter and coil weight, so spring rate and coil behavior remain predictable across batches.
- Diameter and straightness control - diameter, tolerance and straightness are inspected to support stable automatic coiling.
- Oiled surface options - oiled wire reduces friction and die wear on high-speed coiling lines.
- Two grades for different requirements - 82A and 82B grades allow selection between tensile level and forming behavior.
- Full range 0.15-12mm - fine spring wire and heavier sections from one qualified source, with test reports per shipment.
Quality Control
Each batch is inspected for grade, diameter, tolerance, straightness, surface condition, tensile properties and packing against the agreed specification. Test reports are available per shipment.
Quick Selection Guide
- Confirm the spring type (compression / extension / torsion / formed part)
- Select the grade (82A / 82B per tensile requirement)
- Confirm the wire diameter within 0.15-12mm
- Specify the surface (bright / oiled)
- Confirm coil weight and packing for your coiling equipment
Send your grade, diameter, tensile requirement and spring design for a technical confirmation and quotation.
