Note: Per EIGA Oxygen Pipeline and Piping Systems all common metallics are safe for use in systems with Nitrous. Thus propellant compatibility is not a concern. 3.1ksi ish 1/2” OD piping is what we’re looking at

Workability |
| Dissimilar metals can be a concern given that fittings are generally steel. |
| Very difficult to work. |
All Materials work for Ethanol and N2o | Brass is more corrosion resistance than aluminum | Aluminum oxide is a debris in the system | More susceptible to rust | resistance to corrosion |
Thermal Compatibility | -100*F copper | -270*F | (-50* F - 800*F) | (-50* F - 800*F) |
Pressure Comparability | Copper goes up to 1.5ksi. Brass goes up to 2.2ksi | @ 3.3 ksi | Can corrode very easily due to oxidizer. | 3.2 ksi |
