High-temperature properties of aluminum alloy EN6082AW T6

An optimum selection of alloy for aluminium structures exposed to fire

“…A special problem in civil engineering practice is the behaviour of aluminium when subjected to elevated temperatures (fire). Considering the topicality of worldwide research focusing on the behaviour of aluminium in fire [5][6][7], the studies on behaviour of aluminium alloys and structural elements in fire conditions have also been a subject of research in the Republic of Croatia [8][9][10]. Aluminium structures are sensitive to the effects of high temperature due to the high value of the thermal conductivity coefficient (>100 W/m 2 K) and the low melting point of the material (between 560-660 °C) [5][6][7].…”

“…High value of thermal conductivity causes faster heating of aluminium compared to steel, while low melting temperature increases creep sensitivity of aluminium, which was the initial motivation for the research started in the Republic of Croatia. Current research in the field of aluminium behaviour in the field of fire in the Republic of Croatia is related to the analysis of time-dependent deformation (creep) that occurs in the presence of certain thermo-mechanical boundary conditions, all of which have been presented in a series of scientific papers [8][9][10]. The aforementioned studies demonstrated the creep sensitivity of aluminium columns and quantified their creep resistance expressed as the total time during which aluminium columns retain their load-bearing capacity for a given temperature and load utilization factor.…”
