Pre-drawing wire

Pre-drawing wire is a wire rod or semi-finished wire product supplied in coil form, used as the starting material for further wire processing. It is produced via casting, rolling, or extrusion and is then subjected to multi-stage cold forming, such as drawing, rolling, or profiling, to achieve the desired final dimensions, surface quality, and mechanical properties.

Pre-drawing wire features a consistent cross-sectional shape along its entire length, which may be approximately round, triangular, or polygonal. The maximum cross-sectional dimension typically exceeds 6 mm, making it well-suited for subsequent forming operations.

Key characteristics

• Uniform geometry – Ensures stable, high-efficiency processing
• Defined cross-section types – Round, triangular, or polygonal, depending on application needs
• Optimized for cold forming – Suitable for drawing, profiling, or precision shaping
• Good surface quality – Low surface roughness reduces tool wear and improves finish
• Supplied in coil form – Enables continuous processing in drawing lines or rolling mills

Common materials
Pre-drawing wire is available in various metals and alloy groups, such as:

• Copper and copper alloys
• Brass and bronze
• Stainless and alloy steels
• Nickel-based alloys and special materials
• Aluminium and aluminium alloys

Applications

• Wire drawing plants – For the production of fine wire, medium wire, and profile wire
• Electrical engineering – For conductors, multi-strand wires, or contact wires
• Spring and fastening technology – As a base for spring and bent wire production
• Medical and precision industries – Starting material for micro wire or shaped profiles
