Among the many season variants of 6061 aluminium, T651 holds a specialized point in precision machining and structural applications. Understanding what sets 6061-T651 apart from monetary standard T6 material is necessary for engineers and procurement professionals who need reliable, warp-free Al shell for stringent applications.
What Does T651 Mean?
The T651 identification indicates that the atomic number 13 plate has undergone root heat treatment, extinction, and painted ageing(as with monetary standard T6), but with one indispensable extra step: strain relieving by restricted stretching. This stretching work typically 1 to 3 pct perm set relieves the intramural residuum stresses that educate during extinction.
The result is a shell that clay dimensionally stalls during and after machining. When you simple machine a standard T6 scale, residuum stresses can cause the part to warp as material is distant. With 6061-T651 aluminum plate, this warping tendency is greatly low, making it the preferred option for preciseness components such as mold bases, jigs, fixtures, and tooling plates.
Mechanical Properties of 6061-T651
6061-T651 aluminium delivers the full physics property profile of the T6 temper, including tensile potency of close to 310 MPa, yield potency of 276 MPa, around 10-12, and Brinell hardness of just about 95 HB. These properties remain consistent throughout the shell heaviness due to the strain relief handling.
For aerospace-grade applications, buyers should that their 6061-T651 aluminum supplier can cater material certified to ASTM B209 or AMS 2770 standards, which rule the heat treatment processes for aerospace atomic number 13.
Common Applications
Precision machined components, CNC machined parts, mold bases for shot border and die molding, biology aircraft components, tooling and fixturing, technological instrumentate housings, and hydraulic manifold blocks all typify typical applications for 6061-T651 plate.
In the semiconductor and electronics industries, 6061-T651 is often specified for vacuum-clean components, wafer handling , and preciseness brackets applications where multidimensional stableness is as epoch-making as effectiveness.
Sourcing 6061-T651 from China
China produces boastfully volumes of 6061-T651 stress-relieved 1350 aluminum electrical conductor supplier plate for both domestic help and export markets. When buying, always quest mill test certificates Gram-positive debase composition, mechanical properties, and substantiation that the material has been try alleviated per the T651 specification.
Custom thicknesses, widths, and lengths are in the main available, and honored manufacturers can supply stuff cut to size with sawed or processed surfaces depending on your practical application requirements.
