Recycle aluminium has been mixed with palm oil fly ash based on fraction weight of overall weight of palm oil fly ashes to aluminium recycle. The ratios discussed on this paper are 0%, 3% 6%, 9%, 12% and 15%. The samples have been developed via sand casting method. The result shows that the best composition has been achieved when we added 3% of palm oil fly ashes, with the new composite aluminum have a highest hardness with the value of 119.7HV, with the Modulus of raptured of 7.71Mkg/m2

In this experiment, comparison analysis of mechanical properties, porosity and grain size of Pure Al (powder), 95%AL + 5% B4C (With sand casting method) and 95%AL + 5% B4C (With ECAP method) are determined. The ECAP method value is much greater than the sand casting method,because of metal matrix composite microstructure refinement during the pressing operation. Because of material porosity value decreases, powder particle consolidation, the closure of porosity, grain refinement and improve in dislocation occurs as ECAP method gives the results of Mechanical properties as like tensile strength 105.8Mpa, Hardness 94HV, density 888.88kg/m3values increase. At the same time, porosity and grain size value will be reduced because of individual power consolidation happening during ECAP methods like as 1.63% and 8μm. In this metal matrix composite is applied to aeronautical and automobile industry

A new approach to evaluate fluidity of semi-solid rheo-slurries was developed. The equipment was designed in order to reduce pouring error by using bottom tapping and heated tapping ladle. Commercial AC4C aluminum alloy slurries were tested in spiral sand mold by gravity casting. The slurries were prepared by introducing fine gas bubbles into molten metal above the liquidus temperature at different rheocasting times. Average fluidity and microstructures of cast spirals were reported. Results show that the spiral microstructure is non-dendritic and the fluidity of AC4C alloy decreases with increasing solid fraction. In conclusion, the spiral casting method using bottom tapping can be used to evaluate the fluidity of rheocast slurries in gravity sand casting.

Aluminum 6061 Alloy

This research is aimed to get a better understanding on the effort of reducing the porosity level in aluminum alloys. The degassing process (2, 5 and 8 minutes) is done to reduce the hydrogen content in liquid aluminum and cooling rate modifications (13 °C / min, 20 °C / min and 26 °C / min) was performed to reduce the porosity by reducing the size of Dendrite Arm Spacing (DAS). The casting method used in this research is sand casting and raw materials were melted using an electric furnace at 720 °C. The microstructural images showed the DAS size are decreased by size from 137.3 μm to 87.58 μm obtained from cooling rates of 13 °C / min and 26 °C / min respectively. In the other hand, the level of porosity is also decreased from 3.58% at 2 min degassing and the cooling rate of 13 °C / min to 1.8% at 5 min degassing and 26 °C / min cooling rate. Furthermore, the tensile test results show that the value of tensile strength increases when the DAS size and porosity level are smaller. The highest ultimate tensile strength value is 105.9 and the lowest is 70,53 MPa.

Recycle Aluminum

The development of the automotive industry brings impact of increasing use of aluminum for vehicle components that will ultimately produce more aluminum waste. If it is not addressed properly, it will be a serious problem for the environment. One of the solutions is to recycle the waste of drum brake to be a raw material for motorcycle accessories brake handle. The process of making motorcycle brake handle using the sand casting method can be done by varying the temperatures of casting molten metal which are at temperatures of 650°C, 700°C and 750°C. Furthermore, the testing of the mechanical properties and microstructure of the resulted product is done. The result shows that motorcycle brake handle required high impact strength in which the highest impact strength was 0.011 Nm/mm2 that was obtained when temperature of casting was 700°C.

The effect of tin composition and pouring temperature on the length of fluidity, microstructure, density, hardness, tensile strength and bending of Cu-Sn alloy with sand casting method has been investigated. 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.
