COPPER ALLLOE
Because of their corrosion resistance and the fact that copper alloys have been used for niany thousands of years, the number of copper alloys available is second only to the ferrous alloys. In general
copper alloys do not have the highstrength qualmes of the frrrous alloys, while their density is comparable. The cost per strength-wenght ratio is high; however. thry have the advantagr of ease ofjoining
hv soldering, which is not shared hy other metals that have reasonable corrosion resistance.
