How to bend the round bar?
Round bars can only be bent as one style (i.e. there is no strong axis or weak axis to bend against).
Round bars are solid, which means that they can be easily bent into the shapes required by a project. There are two ways to bend non-circular or non-square bars:
This involves bending a bar along the wider axis of the bar. This means an easier bend, reducing the problem of rippling on the inside of the curve. Bars bent the easy way resemble a belt when completed.
Using a PBH profile bending machine can bend a wide variety of bars, including stainless, aluminum, Inconel, brass, copper, and other alloys. Section bending machines even bends rebar.

Is there a difference between Billet and Bar?
The billet is a semifinished round that has been partially worked but will be further worked to the final size. The bar is finished material that has been completely rolled to size.
This distinction is important. Most specifications have minimum required mechanical properties, which almost always include hardness, yield strength, tensile strength, and ductility. As applications get more demanding, such as low-temperature oil and gas applications and aerospace, additional testing is required which could include toughness, hot stress rupture, hot tensile, and grain size to name a few. Furthermore, these more stringent specifications will actually specify a minimum reduction of area requirement for forging or rolling.
All of these materials start out as-cast material, and mechanical hot working is done in order to completely break up the cast ingot structure and set up the kind of grain structure required to meet the mechanical properties in the specifications.
The bar will have enough reduction to meet all properties. The less expensive billet may not always have enough reduction and may not meet all specification requirements.
