7075 T651 aluminium extrusion profiles is regarded as the best product of aluminium alloy. T651 indicates that the alloy T6 and T651 have 572 MPa tensile strength and 503 MPa yield strength after heat treatment and pre-stretching. At the same time, 7075 alloy has good mechanical properties and anodic oxidation properties. ASTM Standard Degree Trade Union of the United States assesses 7075 alloy as type B mechanical properties because of its ability to produce curls or fragile chips, and excellent properties. Surface treatment.
Brief Introduction of
7075 T6510 aluminium extrusion profiles Alloy:
7075 T651 aluminium extrusion profiles can be slightly straightened after stretching, while
7075 T6510 aluminium extrusion profiles can not be straightened after stretching.
Brief Introduction of
7075 T6511 aluminium extrusion profiles:
7075 T6511 has more stretching stress-relieving technology than
7075 T6.
7075 T651 can be slightly straightened after stretching. 7075 T6511 needs slight straightening (roll straightening) after stretching (tension straightening) to meet dimensional tolerance, while T6510 is not straightened after stretching.
Summary: The three forms of 7075 are the same material with the same chemical composition.
7075 T6/T651/T6510/T6511 aluminium alloy are in different heat treatment states. Their mechanical properties are similar. The internal stress of T651 is smaller than that of T6, so it is not easy to deform during processing.
