aluminum sheet 6061 t6 vs t651

The processing performance of 6061 aluminum alloy sheet has good corrosion resistance, high toughness and remarkable oxidation effect. 6061 t6 aluminum sheet and 6061 t651 aluminum sheet are two tempers of alloy aluminum sheet 6061, and they are similar and different. Next, let’s compare the performance of aluminum 6061 t6 vs t651.

aluminum-6061-t6-vs-t651-1

aluminum 6061 t6 sheet plate

6061 t6 aluminum sheet has high strength, high hardness (up to HB90 degrees or more), good processing effect, and good oxidation effect. In addition, T6 has no trachoma pores and good flatness. It is the best choice for low-price and high-quality materials. The 6061-T6 aluminum plate series is an alloy of aluminum, magnesium, and silicon, which is a heat-treated corrosion-resistant alloy.

aluminum 6061 t651 sheet

T651 can also be called t6511, but the writing form is different. After heat treatment and pre-stretching process, 6061 t6511 aluminum properties are excellent, and because of its magnesium and silicon alloy characteristics, aluminum 6061 t651 has excellent processing performance, excellent welding characteristics and electroplating. At the same time, 6061 t651 aluminum has good corrosion resistance, high toughness and no deformation after processing. And t651 is easy to polish and has excellent oxidation effect.

The difference between 6061 t6 vs t651 internal stress

The difference between 6061 aluminum plate state T6 and T651 is that under normal circumstances, the internal stress of T6 will be relatively large, and the processing will be deformed. The state suitable for processing should be T651, which is stretched on the basis of T6 to eliminate internal stress.

The difference between t6 and t651 processing methods

T6: Solution treatment + artificial aging, suitable for products that do not undergo cold processing after solution heat treatment (straightening and leveling can be carried out, but the mechanical performance limit is not affected).

T651: Solution treatment + artificial aging + a certain amount of stretching to eliminate internal stress, suitable for thick plates, rolled or cold finished bars that are stretched according to the specified amount after solution heat treatment or cooling from the high temperature forming process As well as die forgings, forged rings or rolled rings, these products are no longer straightened after stretching.

The difference between t6 and t651 applications

Under normal circumstances, if there is no precise requirement for dimensional stability and elastic margin, the T6 state is used; for precision workpieces, in order to avoid elastic recovery after processing and the size cannot be stabilized, T651 should be used.
