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

All can oxidize and have debris

Aluminum oxide is a debris in the system

More susceptible to rust
