Abstract

The Cu-Sn composite is one of material for frangible bullet application. Frangible bullet are designed to disintegrate on impact against rigid surfaces to avoid ricochet hazards in shooting ranges or law enforcement training facilities. The manufacturing process of CuSn is based on powder metallurgy with variation of weight percent of Sn and compacting pressure. Sintering is performed at temperature of 260°C within 30 minutes period with nitrogen gas atmosphere. The secondary phase (Cu3Sn and Cu6Sn5) was identified. The highest density and hardness are 7,446 g/cm3, 83 HRF for Cu-5 wt% Sn at 500 MPa. The pressure strength and modulus of elasticity are 275,72 MPa and 59,43 GPa.
