Metal Bending Chart!


Thanks to my training partner for providing the data!


Some of this information will probably prove more useful to people in Central Ohio than to others (unless you have a McConnell's or Schreiner Hardware store in your area). But, it should be usefull to get a general idea of which bends requires more strength (e.g. Which is more difficult to bend: 7" x 1/4" Brass or 7" x 3/8" Aluminum? The answer is the aluminum.). This info should prove useful to you to develop a bending strategy to bend progressively more challenging metals. Train smart!
