Bright Manufacturing Wire

Liberty Steel produces a range of Bright Low-Carbon Wire for general manufacturing applications. These wires are cold drawn to the required diameter and not subjected to any subsequent treatment process. They are often used for automotive and agricultural components, shopfittings and shelving where finished components are subsequently electroplated, powder coated or painted to the desired customer finish.

These hard drawn low-carbon wires will take moderate bending or flattening, machineability is fair and the wire can be roll threaded. A dedicated range of products for high-speed 2D and 3D bending machines including Truform® and HiForm® wire extends our traditional hard drawn low-carbon material range.

This is a general purpose manufacturing wire suitable for a large range of applications. Various applications include display shelving for retail stores, baskets, racks, hooks, automotive and general engineering and construction components.

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 +/- 0.05
over 5.00mm up to and incl. 8.00mm +/- 0.06
over 8mm +/- 0.08

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 500/800
