Almost every gas stove nozzle on the market is made from one of two metals: brass or aluminum. Both meter gas flow, but they behave very differently over years of use. For parts wholesalers, knowing the difference is what lets you recommend the right nozzle for each customer and each market. Here is a clear comparison.
Brass is the traditional choice for gas nozzles, and for good reason. It machines to precise, stable apertures, resists corrosion from moisture and fuel impurities, and holds its thread integrity through repeated install-and-remove cycles. For the precision 0.45mm to 1.35mm apertures that gas metering demands, brass delivers consistent, repeatable flow year after year.
Aluminum nozzles are lighter and cheaper to produce, and they work well in dry climates and low-corrosion environments. They are common in cost-sensitive applications where the nozzle is treated as a consumable. However, aluminum is softer and more prone to galling and thread wear, so it demands gentler installation and shorter service life.
The deciding factor is often the environment. In humid coastal regions — or anywhere LPG carries trace impurities — brass resists the pitting and oxidation that can slowly enlarge an aperture and change the gas flow. A nozzle whose aperture has drifted is a safety risk, not just a performance issue. Brass simply holds its calibration better over time.
Nozzles are swapped during conversions and repairs, so thread life matters. Brass threads stand up to repeated torquing; aluminum threads strip more easily. For installers who convert stoves between LPG and natural gas, brass is the dependable standard.
