Among the many mollify variants of 6061 atomic number 13, T651 holds a special place in precision machining and structural applications. Understanding what sets 6061-T651 apart from monetary standard T6 stuff is requisite for engineers and procural professionals who need dependable, warp-free Al shell for needy applications.
What Does T651 Mean?
The T651 designation indicates that the Al shell has undergone solution heat handling, extinguishing, and ersatz ripening(as with standard T6), but with one critical additional step: try relieving by restricted stretch. This stretch work typically 1 to 3 pct perm set relieves the intragroup residuum stresses that train during extinction.
The lead is a shell that stiff dimensionally horse barn during and after machining. When you machine a standard T6 scale, residuum stresses can cause the part to warp as material is distant. With 6061-T651 1350 Aluminum plate, this warping tendency is greatly reduced, making it the preferred choice for precision components such as mold bases, jigs, fixtures, and tooling plates.
Mechanical Properties of 6061-T651
6061-T651 atomic number 13 delivers the full mechanical prop visibility of the T6 season, including tensile effectiveness of close to 310 MPa, yield strength of 276 MPa, around 10-12, and Brinell callousness of just about 95 HB. These properties continue homogenous throughout the scale heaviness due to the strain ministration handling.
For aerospace-grade applications, buyers should that their 6061-T651 aluminum supplier can ply material certified to ASTM B209 or AMS 2770 standards, which rule the heat handling processes for aerospace Al.
Common Applications
Precision machined components, CNC machined parts, mold bases for injection molding and die molding, morphological aircraft components, tooling and fixturing, technological instrument housings, and hydraulic multiply blocks all typify normal applications for 6061-T651 shell.
In the semiconductor and industries, 6061-T651 is often specified for vacuum-clean chamber components, wafer treatment equipment, and preciseness brackets applications where multidimensional stability is as prodigious as potency.
Sourcing 6061-T651 from China
China produces vauntingly volumes of 6061-T651 stress-relieved aluminum plate for both domestic and markets. When buying, always request mill test certificates positive alloy writing, physics properties, and confirmation that the material has been stress eased per the T651 stipulation.
Custom thicknesses, widths, and lengths are in general available, and esteemed manufacturers can ply material cut to size with sawed or milled surfaces depending on your application requirements.
