en Research Paper Research Paper This paper reports the wear behavior of <em>Cu</em>, high <em>Cu-Sn</em> alloy, high <em>Cu-Pb</em> alloy and high <em>Cu-Sn-Pb</em> alloy under dry sliding at ambient conditions. These four materials were chosen for the wear resistance characterization of <em>SnPb</em>-solder affected old/scraped copper (high <em>Cu-Sn-Pb</em> alloy) to explore its reusing potentials. Wear tests were conducted using a pin-on-disk&nbsp;tribometer with the applied load of 20N for the sliding distance up to 2772 m at the sliding speed of 0.513 ms^-1. The applied load was also changed to observe its effect. The investigation reveals that the presence of a little amount of <em>Sn </em>increased the hardness and improved the wear resistance of <em>Cu</em>, while a similar amount of <em>Pb</em> in <em>Cu</em> reduced the hardness but improved the wear resistance. The general perception of &lsquo;the harder the wear resistant&rsquo; was found to match partially with the results of <em>Cu, Cu-Sn</em> alloy and <em>Cu-Sn-Pb</em> alloy. Coefficient of friction (COF) values revealed non-linearly gradual increasing trends at the initial stage and after a certain sliding distance COF values of all four sample materials became almost steady. <em>SnPb</em>-solder affected <em>Cu</em> demonstrated its COF to be in between that of <em>Cu-Pb</em> alloy and <em>Cu-Sn</em> alloy with the maximum COF value of 0.533.
