ABSTRACT:
In order to provide a method of producing magnetron anode at a good mass-produceability, according to the invention, so-called straight type steel cylinder blank the inner peripheral surface of which is not tapered is used and, at the same time, the step of quench-hardening of the steel cylinder blank is omitted. After fitting a copper block to the inside of the straight type steel cylinder blank which has not been quenched, both members are compacted to each other. Then, a press working is effected on the copper blank such that the steel cylinder blank and a back-up punch are forced to move relatively to each other, when a press-working shaping punch is forced into the copper block, thereby to form a copper anode. In order to avoid the bursting of the steel cylinder blank, the press work on the copper block is effected at a temperature of 200.degree. to 650.degree. C.
