Nozzle Materials
Most nozzle parts are available in several materials. Here are the main
features of each kind:
Brass:
•
moderately expensive
•
resists corrosion from most pesticides
•
wears quickly from abrasion
•
probably the best material for general use
•
liquid fertilizers will corrode.
Plastic:
•
moderately expensive
•
will not corrode
•
resists abrasion better than brass
may swell when exposed to organic solvents.
Stainless Steel:
•
•
moderately expensive
•
resists abrasion, especially if hardened
•
good corrosion resistance
suited for high pressures, especially with wattle powders.
Aluminum:
•
•
inexpensive
•
resists some corrosive materials
•
is easily corroded by some fertilizers.
Tungsten Carbide and Ceramic:
•
very expensive
•
highly resistant to abrasion and corrosion
