The　world＇s　first　database　on　the　effect　of　stabilizers　on　the　resistivity　and　thermal　conductivity　of　20　different　commercial　REBa2Cu3O7-delta　(REBCO)　tapes　was　established.　The　resistivity　and　thermal　conductivity　in　the　radial　and　circumferential　directions　were　listed.　The　charging　loss　and　self-protection　ability　of　20　different　commercial　REBCO　tapes　in　the　no-insulation　coils　were　evaluated　via　simulation.　By　comparing　and　analyzing　the　data,　the　Cu/Ag　interface　was　found　to　be　the　most　probable　primary　factor　determining　the　resistivity　and　thermal　conductivity　of　REBCO　tapes.　Such　a　database　can　support　abundant　data　for　the　design　of　the　REBCO　magnet　or　even　the　choice　of　REBCO　switch　or　current　lead.　Another　goal　was　to　help　the　REBCO　manufacturers　find　a　feasible　way　to　adjust　the　resistivity　and　thermal　conductivity,　thereby　meeting　different　requirements　of　the　REBCO　magnet.
