Abstract:The factors of thulium，excessive silicon，Al-Ti-B thulium additive and quench with wind and with water， which influence the intension of 6063 aluminum alloy, were investigated. The change of the inner structure were illustrated in theory. The results show that the amount of thulium and Al-Ti-B and thulium additive and the way of heat treatment have influence on intension.
Key words: 6063 aluminum alloy; thulium; Al-Ti-B; improving intension
