Material designation Material properties and typical applications EN Cu-HCP Chemical composition* deoxidized, oxygen free *Reference values in % by weight Wieland-K12 is an copper which is resistant during heat treatment in reducing atmosphere (resistant to hydrogen embrittlement according to EN ISO 2626). As the amount of phosphorus added for deoxidation is only limited, the material retains its high electrical and thermal conductivity. Joining operations such as soldering and welding are possible without restriction. Physical properties* Types of delivery Electrical MS/m > 57 Thermal conductivity W/(mK) > 385 Thermal expansion coefficient *Reference values at room temperature The Extruded and Drawn Products Division supplies bars, wire, sections and tubes. Please get in touch with your contact person regarding the available delivery forms, dimensions and tempers. Fabrication properties Capacity for being excellent mechanical good cold worked electrolytic excellent Corrosion resistance Pure copper and high-copper alloys generally exhibit good corrosion resistance due to their inert character and are practica[[y insensitive to stress corrosion cracking.
