The coefficient of linear expansion initially decreases sharply with addition of nickel, then more slowly (Fig. 8). The specific heat (at 20 °C) of copper is 0.385 J/(g.K) and of nickel is 0.452 J/(g. K). As nickel content increases, it first diminishes slightly and a mean value of 0.377 J/(g.K) can be expected.
