Aluminum cylinders are lighter, more corrosion-resistant, and preferred for reactive and corrosive gas mixtures such as HCl, H₂S, and HCN because their treated inner surfaces minimize gas degradation. Steel cylinders offer higher pressure ratings and are suited for non-reactive gases. SpecGas uses proprietary internal cylinder treatment on aluminum cylinders to maximize stability and shelf life for reactive specialty gas blends.
