The high strength heat resisting aluminum bus tube is manufactured by Chalco Aluminum through special processing techniques such as horizontal hot top casting, transverse perforation hot rolling, deformation heat treatment and cold drawing, using its own new materials of high performance rare earth Aluminum alloy and heat resistant Aluminum alloy.Among them, the latest development of 6 z63 (6063 - Zr) of  high strength heat resisting aluminum bus tube added rare earth and rare metals zirconium, besides having the advantages of conventional pipe busbar,  more important is 6z63 (6063 - Zr) of high strength heat resistant aluminium alloy tubular busbar can work at a higher temperature (150 ° C to 200 ° C) safe operation, high temperature (250 ° C) soften the mechanical properties (tensile strength) can keep the normal temperature of more than 88%, reached more than 200 mpa, the welding heat affected after OuDeQiang degree coefficient reaches room temperature of more than 80%,It is more suitable to be used in the ice melting plant project, large capacity substation project, old substation reconstruction project and the place with high temperature requirement.
