COPPER ALLOYS FOR TUBE BENDING
Tube bending is a metal forming process used to permanently form tubes by bending them, it can be used for a range of profiles and tube forms. Tube Bending is a complex process and getting the right product is dependent on a number of parameters like pipe diameter, thickness, end-use, and most importantly the alloy of the tube.
Mandrels are used as internal support for tube bending and their purpose is to avoid defects such as collapsing or crinkling of the inner radius of the bent tube. Made in different configurations depending on wall thickness, pipe diameter, and bend radius.
Wiper dies is a tool in a rotary-draw-bending machine that prevents deformation in the form of wrinkles that occurs when the material exceeds its elastic limit and sets in the curve. As the pipe is drawn into the bend, it becomes plasticized at the point of the bend.
QA520H: Aluminum Bronze QA520H is a high-strength alloy with excellent wear resistance suited for thicker wall-thickness tubes and pipes.
QA500H: Aluminum Bronze QA500H are suitable for Wiper Dies as they exhibit good wear resistance and anti-galling properties
