Oxygen-free black anneal wire for Airbag Emitter

 Hard Drawn Low Carbon Wire has been cold drawn to the required diameter and heat treatment is available. Often used for plating, redrawing and coating, it is important that the surface finish of the wire is clean and smooth. It will take moderate bending or flattening, machine ability is fair and the wire can be roll threaded.

This is a general purpose manufacturing wire suitable for a large range of applications. Various applications include super market trolleys, shelving, baskets, racks, hooks and general automotive parts.

Hard Drawn Low Carbon Wire Specifications

Diameter Properties

Hard Drawn Low Carbon Wire is manufactured to comply with the following diameter tolerances:

Nominal Wire     Diameter

Tolerance (mm)

1.60mm up to     and incl. 1.80mm

+/- 0.02

over 1.80mm up   to an incl. 2.80mm

+/- 0.03

over 2.80mm up     to and incl. 5.00mm

+/- 0.03

over 5.00mm up   to and incl. 8.00mm

+/- 0.03

Tensile Strength (MPa)

The tensile strength is defined as the maximum load achieved in the tensile test, divided by the cross-sectional area of the wire test. The tensile strength developed depends on the amount of reduction in area to the finished size. Tensile is not considered of prime importance to this product however the following table is given as a general guide:

Nominal Wire     Diameter

Tensile Range     (Mpa)

less than or     equal to 1.75mm

800/1100

over 1.75mm up   to and incl. 2.00mm

750/1050

over 2.00mm up     to and incl. 2.24mm

700/1000

over 2.24mm up   to and incl. 2.70mm

650/950

over 2.70mm up     to and incl. 2.80mm

600/900

over 2.80mm up   to and incl. 4.20mm

550/850

over 4.20mm up     to and incl. 10.00mm

500/800

over 10.00mm   up to and incl. 11.50mm

450/750

over 11.50mm     up to and incl. 12.50mm
