Question

Up to what size can wires can be drawn by wire drawing process?

(a) 0.01mm

(b) 0.02mm

(c) 0.03mm

(d) 0.04mm

The question was posed to me during an internship interview.

This key question is from Extrusion and Wire Drawing topic in chapter Forming Process of Casting-Forming-Welding II

Answer 1

Correct answer is (c) 0.03mm

To explain I would say: It may be counted among one of the limitations of drawing process, that very thin wires can only be drawn from it. In wire drawing process, wires can be drawn up to the size of 0.03mm.
