Abstract
Changes in tensile strength of recycled aluminium from the piston as a problem encountered. The objective of this research is to know the tensile strength of recycled aluminium from piston for the next use. The methods used are: design and manufacture of tensile specimen mold, specimen casting, tensile testing, material composition testing and data analysis. The test results showed that the tensile strength of the motorcycle piston aluminium worth 376 MPa was decreased to 191 MPa for the 1st recycled (49%) from the 1st recycled to the 2nd recycled value of 118 MPa (38.3%) and from 2nd recycled to 3rd recycled worth 117 MPa (0.8%) caused by loss of elements during recycling include Cu, Si and Fe. The shrinkage tolerance in a successful foundry into a tensile test specimen is smaller than 6%. The SEM photographs show that the porosity of the 3rd recycled aluminium is less than in the 2nd and 1st recycled which means the solubility of the alloying element is preferable, wherein the insoluble elements (Cu, Si and Fe) are decreased.
