6351 aluminium flat bar tube

6351 aluminum alloy is one of the 6 series alloys with higher strength. The strength is higher than 6061 alloy and slightly lower than 6082 alloy. For example, 6351-T6 aluminium profile requires a minimum tensile strength of 295Mpa and good extrusion formability. 6351 aluminium flat bar tube is an extruded structural part of a vehicle, a pipeline for water, oil, etc.
