Brass alloy consists of copper and zinc. It is used as an industrial material because of its hardness and workability, high corrosion resistance, magnetism and good forging ability. This paper evaluates the mechanical properties of brass alloy subjected to cold working which caused plastic straining of the surface of brass specimen resulting from burnishing forces. Forces have a significant role in a burnished surface of brass sample which squeeze it against the samples making plastic twisting of the specimen surface. Burnishing results under variable forces are investigated. The best results of surface roughness have the forces rate of more than 100 N. with a feed rate (0.07 mm/rev).
