ABSTRACT:
A multi-layer metal composite for microwave tubing and the like, which comprises a tubular shaped copper alloy base metal (e.g., brass or phosphorus bronze) lined with silver. A relatively thin interliner layer of a grain refiner containing copper alloy (e.g., copper-zirconium alloy (C15100), tellurium-copper (C14530), cadmium-copper (C14300), manganese-copper (C15500), alumina-copper (C157XX), beryllium-copper (C17410), or the like) is provided between the base metal and the silver, for limiting diffusion of impurities from the base metal into the silver coating and for maintaining a smooth, relatively constant cross section of silver.
