6061-t651 Atomic Number 13 Plate Properties, Applications, And Sourcing Guide
Among the many season variants of 6061 atomic number 13, T651 holds a specialised direct in precision machining and morphologic applications. Understanding what sets 6061-T651 apart from standard T6 stuff is requirement for engineers and procurance professionals who need trusty, warp-free aluminium scale for exigent applications.
What Does T651 Mean?
The T651 designation indicates that the atomic number 13 plate has undergone root heat handling, extinguishing, and artificial ripening(as with monetary standard T6), but with one vital extra step: strain relieving by restricted stretch. This stretching work on typically 1 to 3 percent perm set relieves the internal residuum stresses that prepare during extinction.
The result is a shell that stiff dimensionally horse barn during and after machining. When you machine a monetary standard T6 plate, residual stresses can cause the part to warp as material is removed. With 6061-T651 5052 Work Hardened Aluminum plate, this warping trend is greatly low, qualification it the preferred choice for preciseness components such as mold bases, jigs, fixtures, and tooling plates.
Mechanical Properties of 6061-T651
6061-T651 Al delivers the full mechanical prop profile of the T6 temper, including tensile effectiveness of around 310 MPa, yield potency of 276 MPa, around 10-12, and Brinell callosity of some 95 HB. These properties stay uniform throughout the shell thickness due to the stress succour treatment.
For aerospace-grade applications, buyers should confirm that their 6061-T651 aluminum supplier can provide material certified to ASTM B209 or AMS 2770 standards, which govern the heat handling processes for aerospace atomic number 13.
Common Applications
Precision machined components, CNC machined parts, mold bases for shot moulding and die casting, biological science aircraft components, tooling and fixturing, technological instrumentate housings, and mechanics multiply blocks all represent normal applications for 6061-T651 scale.
In the semiconductor device and electronics industries, 6061-T651 is often specified for hoover components, wafer handling equipment, and preciseness brackets applications where dimensional stability is as evidential as strength.
Sourcing 6061-T651 from China
China produces big volumes of 6061-T651 stress-relieved aluminum plate for both house servant and markets. When purchasing, always request mill test certificates Gram-positive alloy penning, natural philosophy properties, and check that the material has been stress alleviated per the T651 specification.
Custom thicknesses, widths, and lengths are in the main available, and respectable manufacturers can ply material cut to size with sawed or polished surfaces depending on your application requirements.
