2017 T4 T451 extruded aluminum round bar

Apr 25, 2023

The 2017 T4 T451 extruded aluminum round bar is the first 2 series alloy to obtain industrial applications. It has high strength and good cutting performance, but has poor corrosion resistance. The 2 series aluminum bar is characterized by high hardness, of which the original copper content is the highest, about 3-5%. [1] The 2 series aluminum bar belongs to aviation aluminum and is not often used in conventional industry. With the development of China's aerospace industry, the production technology of 2 series aluminum bars will be further improved.



The alloy element of 2017 T4 T451 extruded aluminum round bar is copper, which is the first 2 series alloy to be used in industry. It has high strength and good cutting performance, but has poor corrosion resistance. 2017 T4 T451 extruded aluminum round bar is used in rivets, general mechanical parts, aircraft, ships, transportation, building structural parts, transportation structural parts, propeller components and accessories
