(gun metal about 20, phosphor bronze about 80). It is very soft, especially when heated to 600, but after forging and rolling it becomes very liard ; it is more difficultly acted Upon by air and water than other kinds of brass, and preserves its golden yellow colour for any length of time, especially if well polished. 'It is used for making bearing's, screw propellers, valves, and many other articles. In general the alloys of Cu and Zn con- taining about | p. C. By weight of copper were for a l...ong time almost exclusively made io Sweden and England (Bristol, Birmingham). These alloys for the most part are cheaper, Larder, and more fusible than copper alone, and form good castings. The alloys con- COPPEB, SILVER, AND GOLD 415 colour of the latter to a considerable degree / with a certain amount of zinc the colour of the copper becomes yellow, and with a still larger proportion of zinc an alloy is formed w hich has a greenish tint In those alloys of zinc and copper which contain a larger Amount of zine than of copper, the yellow colour disappears and is replaced by a greyish colour.
