Non-Ferrous Valve Materials
Non-ferrous materials (bronze, brass, aluminium, titanium) serve niche roles: bronze and brass for water, marine and low-pressure service; titanium for oxidising chlorides and seawater; aluminium where weight matters. Each is chosen for a specific corrosion or weight advantage over steel.
When do you use non-ferrous valve materials?
Non-ferrous materials (bronze, brass, aluminium, titanium) serve niche roles: bronze and brass for water, marine and low-pressure service; titanium for oxidising chlorides and seawater; aluminium where weight matters. Each is chosen for a specific corrosion or weight advantage over steel. This family includes 5 grades in our material library, listed below with their service-temperature limits and common designations.
