Aluminum oxide dispersion strengthened copper (ODS)

Aluminum oxide dispersion strengthened copper (ODS) is a conductive material with excellent heat resistance that does not soften even at high temperatures of 930℃ and high conductivity of over IACS 80%. Since ODS has high strength and high conductivity characteristics that are contrary to other copper alloys, it has been used as electrode materials for resistance welding and spot welding of electric vehicles, relay contacts, various electronic parts such as heat-resistant substrates, and reinforcing materials.

Our strength lies in plastic work technology of aluminum oxide dispersion strengthened copper (ODS). Various sizes can be processed from large diameter to small diameter and irregular shape.

Precision machining and quality control of conductive materials such as precision cutting

Aluminum oxide dispersion strengthened copper (ODS) is known as a material that is difficult to work plastically due to its high heat resistance and strength. However, it is possible to perform ultra-precision cutting according to your needs with our unique technology. In handling valuable materials, we have implemented strict quality control in each process to ensure high-quality manufacturing.
