This paper presents an analysis of the origin, microstructures, and make-up of fines in nonferrous products during rod production and wiredrawing. It includes a morphological genus for these contaminants leading to descriptions of eight different formation mechanisms - surface oxides, abrasive and third body wear, adhesive wear, slivers, surface deformation, delamination, and chemical compounds. It also includes a new method to quantitatively determine the fines-potential of rod samples.

Contradictory results and misidentification of oxide layers on metallic surfaces have caused ambiguity in interpretation of results leading to incorrect use in industrial application. This paper focuses on the effect of experimental parameters, such as electrolyte composition and concentration, current density, coating, time constant, surface roughness, and concentration of depolarizer on cathodic reduction of oxides on metallic wires to yield precise measurement and correct identification of oxide layers.

An instrument, commonly referred to as the "surface oxide tester," is used worldwide to monitor oxide thickness of copper rod for grading and diagnosing the production process. This paper provides a deeper understanding of this test and introduces several enhancements, which dramatically increase test accuracy and repeatability with little increase in test time or complexity. A new automated instrument has been developed to incorporate these improvements and a method of comparing instruments is described.

This paper reviews some steel tire cord manufacturing aspects that can affect fatigue properties like patenting, plating, and diffusion. Other manufacturing issues, both up- and down-stream can influence fatigue. One key to superior fatigue performance lies in plated stock quality; other issues are more intuitively obvious and easily understood and so can be more quickly addressed. Tire design plays a role in real-world carcass-cable fatigue life, the strict domain of tire manufacturers.

A hardened layer around 0.04 mm in depth, referred to as the "additional shear strain layer," is generated beneath the surface layer of the wire, and the additional shear strain layer affects the tensile strength of fine wire. The purpose of this paper is to investigate the cause of an increase in tensile strength. The microstructure of the surface layer was made finer than that of the center layer. It was concluded that the tensile strength of the surface layer was greater than that of the center layer because of this crystal grain refinement.

The United States and Canada share what is often described as the world's longest undefended boundary. In three areas, however, the boundary is situated in the middle of a river that is crossed by a wire-supported suspension bridge. A series of wire bridges have connected the two nations for almost 160 years. This historical paper traces the social, economic, and metallurgical conditions surrounding the use of wire for bridge construction across the U.S.-Canada border, beginning with the first bridge in 1848.
