Copper C10300 bars and rods are high-purity, oxygen-free copper alloys similar to C10100 but with minimal variations in processing parameters. They have excellent thermal and electrical conductivity and are designed for high-reliability electrical systems and industrial uses. C10300 has excellent resistance to hydrogen embrittlement and provides exceptional forming, bending, and weld properties. These bars are typically made with accuracy for high-performance electronic, power, and heat transfer applications. Their clean surface and fine grain structure enable them to perform well in those environments where maximum conductivity and corrosion resistance are crucial for efficiency and durability of operation.
Copper C10300 has 99.95% minimum purity copper with an oxygen content of not more than 0.001%. It has electrical conductivity more than 100% IACS and thermal conductivity more than 385 W/m·K. It has tensile strength of 220–380 MPa in general. It possesses excellent ductility and is therefore applicable for forming and cold working. C10300 has high resistance against corrosion and low volatility with physical stability even in vacuum and at high temperatures. It is also resistant to stress corrosion cracking and is suited for cryogenic and vacuum uses.
