Abstract: A method for producing a Cu--Ag alloy based conductive material containing about 10% to about 20% at % Ag, that involves the steps of continuously casting the alloy into a rod followed by quickly cooling the rod, cold-working the rod to a reduction in area of 80% or more, then heat treating the cold-worked rod at a temperature of 250.degree. C. to 350.degree. C. for 1 hour or more to form a heat-treated rod, and thereafter cold-working the heat-treated rod to a reduction in area of 90% or more as defined based on the cast rod to produce conductive material having a high strength of 700 MPa or more and conductivity of 75% IACA or more.

Abstract: A can for use in a canned motor made of a soft magnetic metal plate. Said metal plate has the magnetically hard direction of the texture oriented to the circumferential direction of the can body. Said metal plate also has the magnetically easy direction of the texture oriented to the normal direction of the can body.
