Constellium Unidal® High-Strength Rolled Precision Aluminum Plate, Milled Both Sides
Categories:	Metal; Nonferrous Metal; Aluminum Alloy; 7000 Series Aluminum Alloy
Material Notes:	Unidal® precision plates offers a combination of dimensional stability and high mechanical strength. The very low internal stress reduces the risk of deformation during machining, thereby reducing the need for extra operations like rough-milling, finishing or rework. Both the flatness and the high quality of the plate surfaces, protected by a plastic film, make surface milling by the end user superfluous. Thanks to the high strength properties, threading is made directly into the metal; thread inserts are not required, thus reducing manufacturing cost and time . Applications include reference plates, transport tables, jigs, robot arms. Information provided by manufacturer
