Abstract
Composition and pouring temperature are important parameters in the casting. Incorrect composition and pouring temperature settings can cause defects in cast product. Material used in Cu-(20-24)wt.%Sn. The pouring temperature was varied 1000°C and 1100°C. The mold was made using a wax pattern and coated in clay (SiO2). The mold has a length of 400 mm, width of 10 mm and thickness of the cavity varied from 1.5-5 mm. The length of the fluidity tends to decrease with the addition of the composition, while the increase in pouring temperature and the thickness of the mold cavity increases the length of the fluidity. The density increases with increasing composition and temperature of the pour. The high density indicates low porosity. Material hardness and bending decreases to increase composition and pouring temperature. Tensile strength decreases with the addition of composition, while the pouring temperature increases
