Gold Rod

Gold Rod is available in purities from 99.9% (3N) to 99.98% (3N8) in hard and as-drawn tempers, combining the noble metal's absolute chemical inertness, high density, and excellent electrical conductivity with the mechanical strength of work-hardened rod stock in a directly machinable format. Unlike annealed gold, the hard and as-drawn tempers provide substantially greater tensile strength and resistance to deformation under mechanical load — critical for precision machined electrical contact pins, connector components, and instrumentation parts where soft gold would deform during assembly or in service. Its density of 19.32 g/cm³, melting point of 1064 °C, and face-centred cubic structure support reliable performance across the temperature range encountered in electronics assembly and precision instrumentation. Gold's resistance to oxidation and surface tarnish under all conditions of service ensures consistent contact resistance throughout the component lifetime — the defining property that makes gold the reference material for high-reliability electrical contacts in aerospace, defence, and precision instrumentation connectors. Electrochemical applications exploit its chemical inertness as a stable, reproducible working or reference electrode material in corrosive or biologically active media. The 3N to 3N8 purity range suits demanding industrial and analytical applications; higher-purity grades are available where trace metallic contamination would compromise electrochemical measurements or surface chemistry studies. In research, gold rod is machined into electrode blanks, spectroscopic substrates, and SERS substrates, and serves as feedstock for high-purity gold film deposition and nanoparticle synthesis.
