        Parametric Investigation of Metals (Au, Ag, Pt and Cu) Using Analytical Hierarchy Process

        Muhammad Asif,Faiz Rasool,Zubair Butt,Muhammad Shahzad,Nouman Ahmad,Abdul Rehman Chishti 한국전기전자재료학회 2019 Transactions on Electrical and Electronic Material Vol.20 No.2

        Metals especially gold, silver, platinum and copper are getting more attention for application in electronics fi eld due to their versatile properties. In this paper, we selected the materials after comparison on the basis of their signifi cant properties. Those properties are conductivity, physical properties, reactivity, cost and demand and supply. We investigate the conductivity of metals at various temperature values, their historically monthly prices along with their worldwide demand and supply. First, we compare their conductivity and resistivity for various values of temperature as well as by adding impurity into them. Secondly, we examined their responses when they are in contact with the atmosphere, their historically monthly prices, availability in the earth crust, and a brief discussion on the structure of these metals. These metals are widely used in electronics and jewelry because of their good conductivity, chemical stability and long lasting. We implemented the analytical hierarchy process for the parametric investigation of these metals which is a general theory of measurement. It has been used to derive ratio scales from both continuous and discrete paired comparison. This comparison is taken from actual measurement which refl ects the relative strength of preferences. The metals are also useful to design electrical stimulator with low-frequency current to regulate the blood of the human body. By using the stimulator at acupuncture points to pass through small electrical signal is useful to control blood fl ow in the human body as well as provides relief in pain.
