bedra, a global manufacturer of precision copper alloys, will present its latest innovations in materials aimed at AI data center hardware and medium- and high-voltage power equipment at IEEE PES T&D 2026, with its Vietnam-based subsidiary representing the company on site. The focus is on materials for higher-current power delivery and liquid-cooling components as rack power density increases, plus contact and structural members used in power transmission and distribution gear.
For liquid-cooled AI servers, bedra highlights high-purity copper used in liquid cooling plates for heat dissipation at GPU and CPU hot spots. The company also points to its Powerway copper alloys, which it says are designed for resistance to high-temperature softening; bedra reports post-brazing strength >30% higher than pure copper, positioning the alloys for smaller liquid-cooling components.
On the power-delivery side inside the data center, bedra describes oxygen-free copper with electrical conductivity up to 101% IACS. The company says the materials are intended to reduce voltage drop and energy loss under high-current conditions. bedra also calls out formability for compact electrical cabinet designs and tight dimensional tolerances for rack-level busbars that it says are compatible with OCP standards, with optional silver and tin plating available.
For grid and switchgear applications tied to rising electricity demand, bedra lists several engineered alloys. bedra18200 is described as a Cu-Cr precipitation-strengthened alloy with about 75% of pure copper’s conductivity, with higher strength and hardness, and resistance to softening, wear, and deformation at elevated temperatures; bedra targets it at stationary contacts, contact stems, contact bases, and other current-carrying structural members. bedra18150 (Cu-Cr-Zr) is positioned as an upgrade for demanding high-voltage environments, with improved creep resistance and high-temperature stability to support reliability and service life. For HV vacuum interrupters, bedra10100 (Cu-OFE oxygen-free electronic copper) is described as a fit for high-reliability parts to reduce energy losses and improve dielectric performance.
The engineering takeaway: as AI pushes higher currents and more aggressive thermal designs, the mechanical stability of conductors after joining steps (like brazing) and the conductivity-strength tradeoff in contact materials become practical constraints, not just datasheet details.
bedra says its Vietnam production facility has 50,000 tons of annual capacity and certifications including ISO 9001, ISO 14001, ISO 45001, and IATF 16949. The company also cites an EcoVadis Bronze Medal and a CDP Grade B rating.
