Billet vs. Cast vs. Cast Materials The exact type of aluminum used is what gives a cast part most of its properties. Billet Aluminum Billet aluminum is generally considered a stronger material than cast. Billet aluminum is tough and looks good. It also gives you perfect precision in design.
Look how thick those walls are! Photo by SuperATV. These presses crush aluminum into shape. Forged aluminum parts have a grain that matches the shape of the part, increasing strength. The primary determining factor for strength, is the specific alloy used. Photo by Sam D. These gears are and precision ground. That makes way more of a difference than the housings ever could.

CAST Cast metal is metal that has been heated up past its melting point and poured into a mould, using one of a number of techniques such as gravity or high pressure die casting, to form the shape of your desired product.

Also remember, steel can have a yield strength of as little as 40, psi to ,00 psi those numbers are off the top of my head and may not be exact.
Now a forged part generally is more ductile than a cast part. One of the reasons is its balance of high tensile strength and ductility. It also responds positively to heat treating, so the surface hardness and the overall material tensile strength can be increased after machining. It is cheaper to machine the part when soft, then heat treat it hard. Now the cost of a forged part would seem to be higher because of needing a set of forging dies and a bajillion ton forging press, but the cost or a forged part is generally much lower than a billet part because once the forging tooling is set up, you just go to town and pump out thousands of parts.
Forged parts are always made in high quantity to justify the cost of the tooling. The cost of tooling amortized over , parts is small. The parts are also close to finished shape, and do not need much machining. Machining generally must be done by workers with more skill and take more time than forging.
Now here is the key with billet parts It depends on what kind of steel the part is made from. A billet part is cut from a solid chunk of steel, so the material does NOT have to be forgeable. You can make parts out of superior strength materials to forging, because you do not have to pick a material that is forgable.
The biggest drawback to a billet part is they must be fully machined. If producing , or , parts, the cost of the machining of all the parts will be much higher than the cost of forging and then finish machining an equal number of parts.
