Oxide Dispersion Strengthened Copper

Due to the dispersion of aluminium oxide in the copper matrix in the diameter of only a few nanometres, and the percentage content is very small, so the dispersion of copper with pure copper and other copper alloys more similar to the electrical and thermal conductivity.

In manufacturing, materials are selected for their different properties. Copper is known for its thermal and electrical conductivity; however, its high manufacturing costs make it a no-go in many applications. ODS copper is a modification that increases strength by incorporating nanometer-sized oxide particles which reinforce the copper to make it stronger. Oxide dispersion-strengthened (ODS) variants improve high-temperature resistance properties and are designed to add strength (e.g., creep rupture, tensile, and fatigue strength) while retaining other good properties. ODS materials have been found to be stable to irradiation of temperatures up to 800 °C.

There are many applications for ODS copper where high strength is needed, such as fusion reactor components, particle accelerators, X-ray absorbers, and more.

We are able to manufacture meters-long ODS copper rods directly from powder.
