Cu(20-24)wt.%Sn were casted in two different pouring temperatures (1000 ºC  and 1100 ºC)  in strip plate pattern sand mold. The sand mold has a length of 400 mm, width of 10 mm with a thickness of the mold cavity varied from 1.5 to 5 mm. The results show that the increase in composition (20-22) wt.% Sn decreases the length of fluidity while the composition (22-24) wt.% Sn length fluidity increase again. Increase of the pouring temperature and mold cavity thickness can increase the length of fluidity. Increasing tin composition and pouring temperature can increase the phase of α structure, porosity, hardness of the alloy and trigger the growth of dendrite columnar and secondary dendrite (DAS) microstructure.While the density, tensile strength and bending strength of the alloy tend to decrease. Increasing tin composition and pouring temperature in Cu(20-24) wt.% Sn caused the alloy to be more brittle.</p>}, number={4}, journal={Journal of Mechanical Engineering and Sciences}, author={Slamet, Sugeng and ., Suyitno and Kusumaningtyas, Indraswari}, year={2019}, month={Dec.}, pages={6022–6035} }
