Can 6061 aluminum be cast?

Can 6061 aluminum be cast?

Can 6061 aluminum be cast?

(OP)
Can 6061 aluminum be cast?
Whats the typical range of pressure and temperature, that 6061 forged at?

RE: Can 6061 aluminum be cast?

No. Cast aluminum alloys follow different classification.
Forging temperature for 6061 is reported as 810-900F (432-482C)

RE: Can 6061 aluminum be cast?

Of course 6061 can be cast - it is cast into an ingot shape prior to wrought processing.

Now, if you want to make a near-net shape part using a standard casting process like sand casting, gravity die casting, etc., then you will encounter problems.

As always, the more information you provide, the more helpful the replies will be.

You might look into cast aluminum alloys 771.0-T71 or 357.0-T6.
They have very high yeilds and tensiles thru heat treat.

Goahead is right, 6061 standard is specific to wrought material. Casting alloys (and there are alloys that are functionally equivalent to 6061). Yes they are cast as an ingot but they are roll formed afterwards and that changes the metallurgical structure, this doesn't happen in cast parts so alloy additions have to be made to compensate for that lack of grain refinement. Cast grain structures are fundamentally different than wrought structures and it affects the performance of the part in different ways. When converting a part from a machined or welded process to casting, that needs to be kept in mind.

RE: Can 6061 aluminum be cast?

Dont forget 713 as it ages it gets stronger, 21 days and it normally hits 36K t x 26K yeild also machines very well

we use it for almost all high strenght apps we run into

But it will srink if you do not no how to rigg the pattern!
