Definition: Unflanged is a term used in engineering and manufacturing to describe a material that has been made so thin that it can be easily bent without causing significant deformation. This means that when a force is applied to a surface, it will deform only slightly but not at all, unlike a thick material that would deform more than 10% of its original shape with the same amount of force. Unflanged materials are often used in applications where flexibility and ease of use are important, such as in
