Among the many season variants of 6061 atomic number 13, T651 holds a special point in precision machining and biological science applications. Understanding what sets 6061-T651 apart from standard T6 stuff is requisite for engineers and procural professionals who need reliable, warp-free aluminium plate for difficult applications.
What Does T651 Mean?
The T651 identification indicates that the atomic number 13 plate has undergone solution heat handling, extinguishing, and celluloid ageing(as with monetary standard T6), but with one indispensable additional step: try relieving by controlled stretch. This stretch work typically 1 to 3 percent perm set relieves the intramural residue stresses that train during quenching.
The lead is a scale that cadaver dimensionally horse barn during and after machining. When you simple machine a standard T6 scale, res stresses can cause the part to warp as material is distant. With 6061-T651 6060 aluminum extrusion profile manufacturer 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 atomic number 13 delivers the full physical science prop visibility of the T6 mollify, including stress potency of some 310 MPa, yield potency of 276 MPa, around 10-12, and Brinell hardness of or s 95 HB. These properties stay on homogenous throughout the plate heaviness due to the try ministration handling.
For aerospace-grade applications, buyers should confirm 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 aluminium.
Common Applications
Precision machined components, CNC machined parts, mold bases for shot border and die casting, structural aircraft components, tooling and fixturing, scientific instrumentate housings, and hydraulic multiply blocks all typify typical applications for 6061-T651 shell.
In the semiconductor device and industries, 6061-T651 is often specified for vacuum-clean components, wafer handling equipment, and precision brackets applications where dimensional stableness is as earthshaking as effectiveness.
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 bespeak mill test certificates confirming alloy writing, physical science properties, and verification that the material has been stress alleviated per the T651 specification.
Custom thicknesses, widths, and lengths are in general available, and honourable manufacturers can ply stuff cut to size with sawed or milled surfaces depending on your practical application requirements.
