Wrought zinc alloys are also fabricated into forged and extruded products, but have found limited application. These alloys are of two systems, zinc–aluminum–copper and zinc–copper–titanium. ZA is used for extrusion and forging, as well as for high-strength gravity and die castings.

In general, the addition of alloying elements to copper increases tensile strength, yield strength and the rate of work hardening. All three of these properties will affect forming characteristics. An example of the effect of alloying is shown in Table 3.

Copper and copper alloys offer a suite of infinitely recyclable materials providing many property combinations suited to a wide range of applications that facilitate and enhance our daily lives. Copper’s performance can be expanded to suit many industrial applications by alloying: making a solid material out of two or more different metals. Copper alloys are metal alloys that have copper as their principal component. They have high resistance against best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both of these are imprecise terms, having both been commonly referred to as lattens in the past. Today the term copper alloy tends to be substituted, especially. Copper provides further precipitation hardening, forming CuAl 2 and an intermetallic of the copper–zinc system. Welding of the hardened high-strength alloys results in a major loss of strength, the high-strength alloys such as (AlZn5Mg3Cu) or (AlZn MgCu) in particular suffering a considerable reduction in strength. The important alloys of copper and zinc from an industrial point of view are the brasses comprised within certain limits of zinc content. That portion of the constitutional diagram which refers to these alloys is given in the Figure 1. Figure 1. Constitutional Diagram of the Copper-Zinc Alloys.

  Brass: % Zn by weight, it's used in musical instruments, valves, and hardware. Nickel silver: 20% Zn by weight, it's used for its shiny silver appearance in jewelry, silverware, model train tracks, and musical instruments. Zinc die casting alloys: >78% Zn by weight, it usually contains small amounts (less than a few percentage points) of Pb, Sn, Cu, Al, and Mg to improve die casting. Only the sand cast alloy was brittle at low temperature. For most alloys the tensile strength, yield strength, elongation and notch tensile strength increased in the temperature range from to 20 K. Ultimate and yield strengths of most alloys are less at 4 K than at 20 K. Discontinuous yielding is evident in all stress-strain curves at 4 K. Abstract. This study analyzes the effects of test temperature and strain rate on the tensile properties of some copper-and zinc-based alloys. The copper-based alloys comprised a leaded-tin and an aluminum bronze, whereas the zinc-based alloys were added with various quantities of by: 1.

Through the development of a wide range of alloys, however, very varied strengths and ductility can be achieved, and this has led to the many.
