The change in the modulus of rigidity caused by cold-working and subsequent annealing was measured on brass wires containing 10.14, 30.15 and 40.24 per cent zinc and a commercial brass wire (32.66 per cent zinc), and compared with that of pure copper wire. The results showed that; (1) in well annealed state, the modulus of rigidity of brass wires decreases quasi linearly with the increase of zinc content, (2) the modulus of rigidity of a brass wire always decreases with the increase of the degree of cold-working, but the relative decrease of the modulus of rigidity compared with the decrease of a pure copper wire equally cold-worked different according to the zinc content and (3) the variations in the temperature coefficient of the modulus of rigidity with the method of cold-working and with the degree of cold-working have a characteristics according to the zinc content.
