MEASURING THE EFFECT OF ADDING COPPER ON THE QUALITY OF THE THERMAL CONDUCTIVITY OF PURE ALUMINUM

In this research, an experimental work had been conducted to measure the effect of adding copper (Cu) with different percentages to the pure Aluminum (AL) and noise variables (error) on the quality of thermal conductivity (k). Alloys had been prepared by changing percentages addition of copper to pure Aluminum and the percentageswere (5, 10, 15, 20&25%). The effect of an average deviation and variability on the thermal properties after an addition of copper through use of normal probability plot. The results shows as that copper percentage was increasing lead to increase thermalconductivity by (15.47%) and the property of thermal conductivity had goodness of fit test and percentages the effect of adding copper to pure Aluminium (AL) and error were (97%, 3%) respectively.
