About Soft Copper Tubing
Annealed Copper Tubing is Soft
Project managers looking to bend soft copper tubing are likely searching for what is termed "annealed" tubing. Annealed tubing is far more malleable (or "bendable") than is drawn tubing. Malleable tubing is far easier to bend into shape and can survive rigorous forming operations. Tables of malleable tubing are seen below in various grades and sizes.
Soft Drawn
Those of you looking for soft drawn copper tubing are probably trying to find data regarding the most malleable of the hard copper tubing grades. See our hard copper tubing pages for more information.
Tables by Grade
The following data involves soft copper tubing available from the Copper Tube Coils Group. Note that some tubing is not bendable by hand, whereas others are bendable by hand. All tubes and coils can be built to print with custom enclosures and secondary operations should your project require this.
