“…Again, particle size reduction due to mechanical rolling also contributed to the increase in hardness of the brass alloy as the percentage reduction increases. As reported by Nowosielski, [14], Song et al, [23] higher zinc content (30%) in combination with higher degree of mechanical deformation can significantly increase the mechanical properties of brass. Thus, increase in dislocation density, high zinc content and particle or grain size reduction due to rolling all contributed to the high hardness value of the deformed brass.…”

“…The deformation characteristics of brass have been studied by Verma et al, [13] and he affirms that higher copper content (larger than 60%) is needed to produce products by cold working so as to have enough formability. Higher zinc content in the brass promotes brittleness and optimal mechanical properties are display in brass containing 30% zinc which is characterized by considerable plastic properties together with high tensile strength and hardness [14].…”

The mechanical properties as well as microstructure of Cu-30.6 wt% Zn alloys containing 0.01 wt% lead has been investigated. The brass alloy was cast and then cold rolled at various percentage reductions: 20%, 25%, 30%, 35% and 40% followed by stress relieving annealed at 450˚C. Hardness, ultimate tensile strength (UTS) and impact toughness values were evaluated at every stage of reduction. It was discovered that the strength, hardness and impact energy all increased with increased percentage reduction. Finally, the optical microscope of the samples was done and the result achieved correlated with the mechanical properties.

“…The % of zinc added to brass varies from 30 to 42% and is easily hot worked for improved strength, but the higher content of zinc also increases brittleness. Generally, optimal mechanical properties can be achieved by 30% zinc addition and the degree of deformation during production of the alloys, while at the same time heat treatment also has considerable impacts on the mechanical properties of brass alloys [5,6]. Quan Li et al [7] concluded from an experimental analysis that HPb59-1 brass can be replaced by Sb-Mg brass due to its higher mechanical properties and good cutting performance, as well as to protect the environment.…”

The significant demand for copper and brass in industrial applications, the automotive industry and building industry is increasing; this requires the improvement of their mechanical properties by the addition of suitable alloying elements. The objective of this research is to study the effect of adding various alloys to copper and brass and their effects on their tensile strength, hardness and microstructure. The mechanical properties of two copper alloys and two brass alloys have been characterized in terms of tensile strength, impact strength and Rockwell hardness. The mechanical properties and microstructure of annealed specimens of Cu and brass alloys were observed. The results showed that by increasing the addition of alloys, the tensile strength also increases for both cases. The microstructure of the fracture surface after tensile testing has been examined using an inverted microscope. The experimental result shows that after the annealing at two temperatures of specimens of two copper alloys and two brass alloys, E-Cu shows more ductility than pure copper and C38500 brass alloy shows more ductility, yield strength and tensile strength than brass type 1.
