BS 7291 Brass Comparison with Other Metals

Brass tube fittings outperform many other metals in terms of oxidation resistance. For instance:

Steel fittings often require coatings or treatments to resist oxidation, such as galvanization. While these coatings help, they can wear down over time, leaving the steel exposed to rust. Brass tube fittings, by contrast, maintain their antioxidation properties without the need for such treatments.
Copper fittings, while resistant to oxidation, lack the mechanical strength that brass fittings provide. Brass combines copper's antioxidation properties with zinc's added durability, resulting in a stronger and more versatile fitting.
Aluminum fittings resist oxidation well, but they may not offer the same level of strength and durability in high-pressure or high-temperature systems compared to brass.
Overall, brass tube fittings offer an ideal balance between antioxidation, strength, and versatility, making them a preferred option across multiple industries.
