Copper alloys are commonly divided into several categories depending on the alloying element(s) and the amount of alloying. The dominant strengthening mechanism varies according to the same parameters as noted above. Some general comments on the alloy families, based on categories used by the Copper Development Association, follow. The discussion is general due to the […]
Stamping process is used to convert blank metal strip into contacts or shields by cutting and forming it. The press brings the pressure to the die which performs cutting and forming steps. Figure 1.31a illustrates the die into the press, when figure b shows inside the die (in between the two parts). On the c

The vast majority of connector contacts are stamped and formed from copper alloy strip. This discussion of copper strip processing begins with the cast slabs of the chemical composition of the desired copper alloy, say 70 percent copper and 30 percent zinc for cartridge brass. The dimensions of the slabs vary with the alloy and
