Among the many season variants of 6061 aluminum, T651 holds a specialised point in precision machining and structural applications. Understanding what sets 6061-T651 apart from monetary standard T6 stuff is necessity for engineers and procurement professionals who need trusty, warp-free atomic number 13 scale for exigent applications.
What Does T651 Mean?
The T651 designation indicates that the Al shell has undergone solution heat treatment, quenching, and bleached aging(as with monetary standard T6), but with one indispensable extra step: stress relieving by limited stretch. This stretching work typically 1 to 3 percent permanent wave set relieves the intragroup residue stresses that educate during extinguishing.
The result is a shell that stiff dimensionally stable during and after machining. When you simple machine a standard T6 scale, remainder stresses can cause the part to warp as stuff is removed. With 6061-T651 aluminum plate, this warping tendency is greatly low, making it the preferred pick for preciseness components such as mold bases, jigs, fixtures, and tooling plates.
Mechanical Properties of 6061-T651
6061-T651 aluminum delivers the full physics property visibility of the T6 temper, including tensile effectiveness of more or less 310 MPa, yield effectiveness of 276 MPa, around 10-12, and Brinell insensibility of roughly 95 HB. These properties stay homogeneous throughout the plate thickness 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 govern the heat handling processes for aerospace atomic number 13.
Common Applications
Precision machined components, CNC machined parts, mold bases for injection moulding and die molding, biology aircraft components, tooling and fixturing, scientific instrumentate housings, and mechanics multiply blocks all stand for normal applications for 6061-T651 shell.
In the semiconductor device and industries, 6061-T651 is often specified for vacuum components, wafer handling , and preciseness brackets applications where dimensional stableness is as operative as strength.
Sourcing 6061-T651 from China
China produces boastfully volumes of 6061-T651 stress-relieved 5052 Work Hardened Aluminum plate for both house servant and markets. When purchasing, always bespeak mill test certificates confirming alloy authorship, physics properties, and substantiation that the material has been try eased per the T651 specification.
Custom thicknesses, widths, and lengths are generally available, and prestigious manufacturers can provide stuff cut to size with sawed or milled surfaces depending on your practical application requirements.
