ABSTRACT:
A dispersion strengthened copper alloy and a method for producing the alloy are provided. The alloy preferably comprises aluminum, titanium and hafnium as alloying elements that are internally oxidized under controlled conditions to produce a dispersion strengthened copper material having good hardness and high conductivity. A method for reducing the adverse effects of hydrogen on such materials is also provided. The dispersion strengthened material can be useful in many applications, including welding electrodes and electrical contacts.
