All tubing will exhibit springback after a bend has 
been completed . The amount of springback depends 
on the bend angle, bend radius, tubing material, and 
wall thickness .
Experience will help you predict the amount of 
springback . Expect to allow 1 to 3° of compensation .
Note :  Verify the bend angle using a template, 

protractor or against a known angle to ensure 
the desired bend angle has been achieved .

Springback

Note:  Do not bend all the way to the bend mark 

when bending softer tubing such as copper or 
aluminum .

1 to 3°
