Monel is made by combining nickel, copper, iron, manganese and trace amounts of other alloys. The Monel frame has the strength of steel with the weight of plastic and is corrosion resistant as well. Used in the production of jet engines to give strength with the flexibility required to handle the turbulence experienced in flight. A better quality process, in which frames are made of specific alloys, that allow them to keep their shape better than cheap metal frames. There is a process for the production of the frame that has a high degree of tensile strength and resistance to permanent bends. Using an age hardening nickel-bronze alloy, it is capable of being strengthened by a heat aging treatment. There is a tendency for frames to loose their shapes with the application of stress to the frame, but is reduced as compared to similar frames that are not subjected to the heat aging step or frames made of alloys which cannot be strengthened by the heat-aging treatment step.
