Copper Rod - Ø 3.2mm L 10mm

Details

SKU: 1000051827 Product Code: CU00-RD-000120
Copper Rod is a precision-engineered cylindrical conductor made from copper with purity levels ranging from 99.0% to 99.999%, delivering exceptional electrical conductivity (up to >100% IACS), thermal performance, and corrosion resistance. Ultra-high-purity rods are essential in vacuum electronics, microfabrication, and quantum devices, while standard high-purity variants are widely used in energy systems, electromagnetics, and structural conductors. Applications include HV busbars, motor windings, RF components, and earthing rods. Notable use cases involve cryogenic feedthroughs, discharge electrode blanks, and electroplated tooling substrates. Copper rods are central to research in grain boundary conductivity loss, recrystallization under pulsed current, and hybrid joining with non-ferrous alloys. Their unparalleled blend of purity, mechanical stability, and conductivity ensures their enduring value across high-demand applications in electronics, clean energy, and advanced materials development.
