Drawing is a process by which a workpiece is pulled against a die to produce a wire, bar, or tube with smaller cross sectional area compared with the initial stock. This article discusses the variables that affect the drawing process and the parameters that influence friction, lubrication, and wear. These parameters include process, lubricant, workpiece, and tooling. The article provides information on dry and wet lubrication in wire drawing. The dry lubrication refers to use of solid lubricants while wet lubrication refers to the practice of providing a liquid lubricant to the workpiece-die interface. The article describes the most common types and causes of die wear: abrasive wear, adhesive wear, surface fatigue wear, thermal fatigue wear, and catastrophic failure. It concludes with a discussion on the surface treatment and texturing that are used to reduce die wear in drawing operations.

This article is a comprehensive collection of tables containing formulas for metals processing, namely, casting and solidification, flat (sheet) rolling, conical-die extrusion, wire drawing, bending, and deep drawing. Formulas for compression, tension, and torsion testing of isotropic materials are included. The article also lists the formulas for effective stress, strain, and strain rate (isotropic material) in arbitrary and principal coordinates; dimensionless groups in fluid mechanics; and anisotropic sheet materials at various loading conditions.

This article contains nine tables that present useful formulas for deformation analysis and workability testing. The tables present formulas for effective stress, strain, and strain rate in arbitrary coordinates, principal, compression and tension testing of isotropic material. The article also provides formulas for flat rolling, conical-die extrusion, wire drawing, deep drawing of cups from sheet metal, and bending, and formulas for anisotropic sheet materials.

This article provides an overview of the classification system of coppers for conductors and for wires and cables, as well as wire rod fabrication techniques such as rolling and continuous casting. Wiredrawing and wire stranding operations, including the preparation of rod surface, drawing, production of flat rectangular wire, annealing, and coating, are discussed. The article also provides information on electrical insulation and jacketing techniques, including polymeric insulation, enamel insulation, and paper-and-oil insulation.

This article begins with an overview of steel wire configurations and sizes followed by a discussion on various wiremaking practices. The wiredrawing operation is discussed, including cleaning, die design, use of lubricants and welds, finishes, coating, and thermal treatments. Metallic coatings can be applied to wire by various methods, including hot dip processes, electrolytic process, and metal cladding by rolling metallic strip over the wire. These wires are normally grouped into broad usage categories. These categories, as well as some items in each category, are described in the article under their quality descriptions or commodity names. These include low-carbon steel wire for general usage, wire for structural applications, wire for packaging and container applications, wire for prestressed concrete, wire for electrical or conductor applications, rope wire, mechanical spring wire for general use, wire for fasteners, mechanical spring wire for special applications, upholstery spring construction wire, and alloy wire.
