Monel
Monel is a composition of nickel and copper with some amount of iron, carbon, silicon and manganese.
Usage
It is used in aircraft construction, especially in making the frames and skins of experimental rocket planes to resist the heat that is generated by aerodynamic friction of extremely high speed flight.
Forms
- Pipes & Tubes.
- Sheets, Plates and Coils.
- Forged and Buttweld Fittings.
- Rods, Bars and Wires.
- Fasteners.
- Ferrous and Non Ferrous.
