Billet aluminum is stronger than cast.
You start with an aluminum billet chunk (aluminium for the english folks) and CNC machine it into something strong and durable and expensive.
Cast aluminum products come out of the cast mold roughly what it is supposed to be and is then further machined into something less strong and less durable and less expensive.

Billet is usually more expensive because of the labor that goes into producing something from a solid block of material, and the ability/ talent to program the machine corectly to produce the desired product.
Casting is expensive initially to produce the cast, but then the manufacturing process is much less expensive if you intend to mass produce something. The difference in quality (assuming the billet is correct
) is that casting can have core shift, resulting in areas that may be too thin and ultimately having the ability to eventually crack. Casting can also have porosity (holes) in the product which could results in leaks (liquid or vacuum depending on application). And then, depending on the part and function, it may need to be machined on the mating surfaces, but this is much less labor intensive compared to the billet pieces, therefore being less expensive.
A fine example, look at the prices difference between billet wheels and cast

I like that.I asked this tongue in cheek.
Billet means this. I want to sell you something so I'm going to call it Billet If that isn't enough I'll tell you how I manufactered it. CNC or CAD-CAM.
CNC=Cash N Carry.
So this way you know your billet 6061 aluminum t-6 CNCd oil cap mounted on your cast covers will never fail.
The billet fuel filters are threaded aluminum pipe. But are supplied by a cast pump. So a chunk of metal extruded into a pipe is called Billet.
6061 is a very inexpensive but strong aluminum. Thats why its used so widely.
T6 is the hardening of it. Just about everytime I see 6061 listed its always T6!
