FIELD: metalworking.
SUBSTANCE: wire blank intended for mesh fences or catalytic systems and a method for its manufacture. The workpiece contains a metal base with a metal shell consisting of metal layers. The metal shell is made with a bending radius smaller than its thickness, while the metal layers of the metal shell are conjugate with each other, and the areas of their connection are offset relative to each other. In the method, metal layers are fixed around the axis of the metal base, a metal shell is formed, the metal layers are mated to each other, the areas of their connection are shifted relative to each other and recrystallization annealing of the workpiece is performed, while the metal shell is fixed on the base with a bending radius smaller than the thickness of the shell.
EFFECT: creation of a blank resistant to physical impact for manufacture of strong wire.
