The inherent risk of non-demisable Titanium Alloy tanks surviving re-entry and falling to Earth is recognised.  Nammo Space has utilised specially developed forging and friction stir welding capabilities at its Raufoss manufacturing facility to create spacecraft propellant tanks in Aluminium Alloy.

Nammo’s metallurgists and chemists have carried out analysis and propellant compatibility testing of high strength Aluminium alloys with hydrazine derivatives, NTO and Hydrogen Peroxide.  Using the alloys that pass the selection and mechanical performance criteria, tank shells are forged, machined and assembled with moulded diaphragms and appropriate welding techniques.  The tanks are then proven through a complex and intensive inspection and testing regime, before being delivered for propulsion system integration.
