Brass Wire - Material Information

Brass wire, particularly the Cu63/Zn37 composition, is widely appreciated for its excellent balance of strength, corrosion resistance, and machinability. With its golden appearance and versatile mechanical behavior, this alloy remains a top choice across industrial and decorative sectors.

Material Overview

Cu63/Zn37 brass is a binary copper-zinc alloy containing approximately 63% copper and 37% zinc by weight. This composition corresponds to the H63 grade, known for its superior tensile strength (~396.8 MPa) and moderate ductility (elongation ~3.4%) [(Ma et al., 2015)]. The alloy demonstrates high work hardening rates, especially under cold working conditions, and displays cyclic hardening under repeated stress cycles [(Ma et al., 2015)]. The elastic modulus is measured around 97.6 GPa, indicating good stiffness. Brass also exhibits significant resistance to corrosion in atmospheric and saline environments due to the passivating nature of its surface oxides.

Applications and Advantages

Thanks to its strength and formability, Cu63/Zn37 brass wire is used extensively in architectural elements, including grills and reflectors, as well as mechanical fasteners such as rivets and screws. Its excellent thermal and electrical conductivity, combined with its mechanical robustness, also make it ideal for components in electronic assemblies and heat exchangers. Furthermore, its resistance to fatigue and aesthetic appeal contribute to its popularity in musical instruments and decorative applications [(Atay et al., 2020); (Sousa, 2019)].
