High-conductivity alloys
Advantages of high-conductivity alloys
For high-conductivity alloy bars, including copper busbars, copper tubes, and profiled bars, bedra employs large-tonnage vacuum casting technology and rigorous quality management processes. By precisely controlling the size and distribution of precipitated phases, bedra ensures uniform composition and microstructure. For the flagship product bedra18150 alloy, the hardness (HRB) reaches 85 or higher, while electrical conductivity exceeds 88% IACS. This material meets the stringent requirements of high-speed cold upsetting machining and is widely applied in various industry fields including smart terminal devices, welding equipment, special motors (e.g., rail transit and power systems), medical devices, the steel industry, UHV power transmission and transformation systems, precision die-casting molds, and other advanced industries.
