2124 T851 aluminum plate blocks

Jan 25, 2023

Introduction of 2124 T851 aluminum plate blocks:
Compared with T351 state, 2124 T851 aluminum plate blocks not only has higher tensile yield strength, compression yield strength and corrosion resistance, but also has better thermal stability. T351 state has serious tendency of intergranular corrosion, spalling corrosion and stress corrosion, while T851 state has no tendency of intergranular corrosion and spalling corrosion, and has good stress corrosion resistance, but the plasticity and toughness of T851 state are lower than that of T351 state.
