6061-t651 Aluminium Plate Properties, Applications, And Sourcing Guide
Among the many season variants of 6061 aluminum, T651 holds a special aim in precision machining and morphological applications. Understanding what sets 6061-T651 apart from monetary standard T6 stuff is necessary for engineers and procurance professionals who need reliable, warp-free Aluminum-5052-h32 scale for stringent applications.
What Does T651 Mean?
The T651 identification indicates that the aluminium shell has undergone root heat treatment, extinction, and staged aging(as with standard T6), but with one critical additional step: stress relieving by limited stretching. This stretching work on typically 1 to 3 percent perm set relieves the intragroup residual stresses that educate during extinguishing.
The lead is a scale that remains dimensionally stable during and after machining. When you machine a monetary standard T6 scale, residual stresses can cause the part to warp as material is distant. With 6061-T651 aluminum plate, this warping trend is greatly rock-bottom, qualification it the desirable choice for preciseness components such as mold bases, jigs, fixtures, and tooling plates.
Mechanical Properties of 6061-T651
6061-T651 aluminum delivers the full natural philosophy prop visibility of the T6 season, including stress effectiveness of about 310 MPa, yield potency of 276 MPa, elongation around 10-12, and Brinell hardness of close to 95 HB. These properties remain consistent throughout the shell heaviness due to the strain succor handling.
For aerospace-grade applications, buyers should confirm that their 6061-T651 aluminum supplier can provide material secure to ASTM B209 or AMS 2770 standards, which rule the heat handling processes for aerospace aluminum.
Common Applications
Precision machined components, CNC machined parts, mold bases for injection border and die molding, morphologic aircraft components, tooling and fixturing, technological instrumentate housings, and hydraulic manifold blocks all symbolise normal applications for 6061-T651 scale.
In the semiconductor device and industries, 6061-T651 is often specified for hoover chamber components, wafer treatment , and precision brackets applications where dimensional stableness is as epochal as effectiveness.
Sourcing 6061-T651 from China
China produces vauntingly volumes of 6061-T651 stress-relieved aluminum plate for both domestic help and export markets. When purchasing, always bespeak mill test certificates positive alloy writing, natural philosophy properties, and verification that the material has been strain relieved per the T651 specification.
Custom thicknesses, widths, and lengths are in general available, and honourable manufacturers can provide material cut to size with sawed or processed surfaces depending on your practical application requirements.
