Abstract

Fishing boat propellers are generally made of aluminum which is easily damaged when hit by rocks, waves and corrodes. The development was carried out by adding brass (Cu-Zn) to ADC 12. The specimens were successfully made by adding 30% Cu-Zn to ADC 12 using the casting method followed by die casting and sand casting methods. ADC 12 specimens and ADC 12+CuZn alloy were tested for tensile and impact according to ASTM E8 and ASTM E23 standards to determine changes in the mechanical properties of these materials. Based on the results of the tensile test, it was found that the presence of Cu-Zn reduced the tensile strength of ADC 12 (141 MPa) and the alloy ADC 12+CuZn (55.1 Mpa). Impact strength test results show the average hardness level of ADC 12 (15.61 joules) and alloy ADC 12+CuZn (15.98 joules)
