I need to know the difference between billet alum. and 6061 alum.The
reason is , I'm going to machine my own pistonrod for a briggs 5hp
gokart racing engine from aluminum but need to know if the 6061 series
alloy would be strong enough to take the stress and heat of this
environment.There are after market rods advertised as billet alum.Thanks
in advance fo any and all information
Billet is basically a term used to fancy something up. What it means is
someone took a chunk of alum (or what ever material), then machined the
object (in your case connecting rod) out of it. This as opposed to casting
a rod, then just cleaning it up a bit for example.
As for the 6061 being strong enough, I dunno, I'm not real up on metalurigy
(or spelling). But I really don't see why it wouldn't work.

I was told once by an old aircraft mechanical design engineer that billet
aluminum is a more "pure" aluminum than most other aluminum types. All
aluminum has some impurities in it but billet is supposed to be with the
"least" impurities than the rest. That is why it is used in a lot of
military, aircraft, and space applications.
or so I was told.....
Billet is just a chunk of metal. Aluminum billet is a chunk
of aluminum. To make a connecting rod from aluminum billet, you
simply cut away everything that doesn't look like a connecting rod.
Making things from billet is common in the racing, areospace, and
specialty markets since no or very little investment is required
and volumes are very low. To make the same part as a forging
would actually result in a part that was stronger and more fatigue
resistant but would require a much greater investment in tooling.
To pay for that tooling you need volume. For small volume, you get
You will be hard pressed to find anything made from billet on large
volume mass produced goods. If you do, it's because for some
reason or other, the customer is willing to pay dearly for it.
