Commercially available two different compositions of (α+β) brass and lead-tin-brass were annealed, normalized and solution treated at 815°C for 1/2hr. The tensile test data were analyzed to fine the UTS (ultimate tensile strength), elastic modulus, %elongation and reduction in area. The UTS of (α+β) brass with different heat treatments was found to vary between 360.81 to 417.40 MPa with elongation of 8.6-32.0% and between 399.72 to 474.00 MPa with elongation of 4.6-9.9% for lead-tin-brass. The Rockwell hardness (HRF) with these heat treatments was observed to decrease variably for (α+β) brass and also for annealed and normalized samples of lead-tin-brass but increased for solution treated sample.
