Among the many temper variants of 6061 atomic number 13, T651 holds a specialised direct in preciseness machining and morphologic applications. Understanding what sets 6061-T651 apart from standard T6 stuff is requirement for engineers and procurement professionals who need trusty, warp-free Al shell for difficult applications.
What Does T651 Mean?
The T651 designation indicates that the aluminium shell has undergone root heat treatment, quenching, and fake aging(as with monetary standard T6), but with one vital additive step: strain relieving by limited stretching. This stretch work on typically 1 to 3 per centum permanent set relieves the intramural residue stresses that train during quenching.
The leave is a shell that corpse dimensionally horse barn during and after machining. When you simple machine a monetary standard T6 shell, balance stresses can cause the part to warp as material is distant. With 6061-T651 aluminum plate, this warp trend is greatly rock-bottom, qualification it the preferred option 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 natural philosophy prop visibility of the T6 mollify, including tensile effectiveness of or s 310 MPa, yield strength of 276 MPa, around 10-12, and Brinell hardness of about 95 HB. These properties stay consistent throughout the shell heaviness due to the strain ministration treatment.
For aerospace-grade applications, buyers should that their 6061-T651 aluminum supplier can provide material secure to ASTM B209 or AMS 2770 standards, which rule the heat treatment processes for aerospace aluminium.
Common Applications
Precision machined components, CNC machined parts, mold bases for shot moulding and die molding, structural aircraft components, tooling and fixturing, scientific instrumentate housings, and mechanics multiply blocks all represent typical applications for 6061-T651 scale.
In the semiconductor unit and electronics industries, 6061-T651 is often specified for hoover components, wafer treatment equipment, and preciseness brackets applications where multidimensional stability is as meaningful as strength.
Sourcing 6061-T651 from China
China produces boastfully volumes of 6061-T651 stress-relieved 6061-T651 aluminum aerospace grade supplier plate for both domestic and export markets. When purchasing, always call for mill test certificates confirming alloy penning, natural philosophy properties, and check that the stuff has been try eased per the T651 specification.
Custom thicknesses, widths, and lengths are in general available, and esteemed manufacturers can cater material cut to size with sawed or processed surfaces depending on your practical application requirements.
