What is cold drawn steel wire?

It specifically refers to steel wire made by cold drawing process, which is a production method that can be used to cold draw galvanized wire, cold draw low carbon steel wire, cold draw stainless steel wire, cold draw aluminum alloy wire, etc. Its production process is to draw the hot rolled wire through a die at room temperature to reduce its diameter and increase its length, while improving the toughness, precision, durability, strength, and surface finish of the material.

Commonly used materials for cold-drawn steel wires

Weight formula for cold drawing of different materials

1. Weight of Cold Drawn Mild Steel / Medium to High Carbon Steel Wire

Weight (kg/m) = (π × diameter² × 7.85 g/cm³) / 4

 

2. Weight of cold drawn stainless steel (304) wire

Weight (kg/m) = (π × diameter² × 7.93 g/cm³) / 4

 

3. Cold-drawn copper (C1100) wire weights

Weight (kg/m) = (π × diameter² × 8.96 g/cm³) / 4

 

Example: Calculate the weight per meter of mild steel wire with a diameter of 2 mm.

 

Weight = (3.14 × 2² × 7.85) / 4 = 24.63 g/m ≈ 0.0246 kg/m.

Cold drawn Steel Wire Properties

1. High precision: small diameter tolerance (usually ±0.02mm), suitable for precision parts manufacturing, which is not a feature of hot rolling.

2. High strength: cold work hardening to improve tensile strength, suitable for high strength demand scenarios.

3. High quality surface: smooth surface, no oxidized skin, reduces subsequent processing costs.

4. Good dimensional consistency: suitable for automated production, improves assembly precision.

5. Strong customizability: hardness, toughness, and surface treatment can be adjusted according to demand, very flexible.

Cold-drawn wire applications

Commonly used Wire Gauge (Wire Gauge) and typical applications

The specifications of cold drawn steel wire are usually expressed in diameter (mm) or wire gauge (SWG, AWG), and different wire gauges are suitable for different fields:

Wire gauge（SWG）	diameter（mm）	Typical application
8 SWG	4.06 mm	Construction reinforcement, heavy machinery parts
10 SWG	3.25 mm	Structural components, hardware
12 SWG	2.64 mm	Springs, metal mesh
14 SWG	2.03 mm	Wires and cables, hardware
16 SWG	1.63 mm	Automobile parts, fasteners
18 SWG	1.22 mm	Electronic components, precision instruments
20 SWG	0.91 mm	Medical instruments, fine springs
22 SWG	0.71 mm	Electronic connecting wires, jewelry making

Note:

1. SWG (Standard Wire Gauge): British standard wire gauge, widely used in Europe and Asia.

2. AWG (American Wire Gauge): American wire gauge, mainly used in North America.

 

Cold Drawn Steel Wire Application Areas

Construction Industry:

1. Prestressed concrete structure: It has high strength and can provide a strong prestressing force for the concrete structure. Prestressed steel wire is often used in the construction of large bridges, floor slabs of high-rise buildings, and roof panels.

2. Reinforcing steel mesh: It can be used for reinforcement of building walls and floors, and can effectively improve the seismic performance and structural stability of buildings.

 

Mechanical Manufacturing:

1. Spring: with good elasticity and fatigue properties, it is an ideal material for manufacturing various kinds of springs, such as coil springs in automobile suspension systems and winding springs in mechanical clocks and watches.

2. Transmission components: cold-drawn wire can be used as transmission chain or wire rope material; its high strength and wear resistance can withstand greater tension and friction.

 

Automotive Industry:

1. Tire radials: Steel cord made of cold-drawn wire is an important part of automotive tire radials, which can enhance the strength and abrasion resistance of tires. Improve the load-carrying capacity of tires and reduce the rolling resistance of tires.

2. Automotive seat adjustment mechanism: seat slides and adjustable springs, etc., to meet the frequent seat adjustment requirements. Provide reliable support and flexible adjustment performance.

3. Others: Suspension springs, pneumatic rods, clutch wires, brake lines.

 

Other Areas:

1. Overhead transmission lines: often used as ground wire and wire reinforcement core in overhead transmission lines, capable of withstanding large tensile force.

2. Musical instrument strings: piano, violin, guitar, and other stringed instruments, their good sound quality and stable pitch can meet the requirements of musical instruments.

3. Fishing gear: fishing line is sometimes made of cold-drawn steel wire, especially in fishing or for sea fishing. Cold-drawn steel wire made of high-strength, good abrasion resistance, is not easy to be bitten off by fish, and can withstand greater tension.

4. Aerospace: superior to have high strength and corrosion resistance, can be used for high-strength structural components, special wire rope, and stranded chain.

5. Hardware: Nails, screws, bolts and nuts that do not require corrosion-resistant treatment, metal nets, fences.
