Naval Brass
Naval brass, a renowned marine alloy, is characterized by its robustness, high strength, and resistance to corrosion. Comprising 60 percent copper, 0.75 percent tin, and 39.2 percent zinc, this alloy embodies the quintessential maritime material. The inclusion of tin further imparts exceptional resistance to dezincification. Naval Brass is extensively utilized in marine construction, fulfilling the demand for durable, corrosion-resistant, and hard materials in both saltwater and freshwater environments. With commendable strength and rigidity, Naval Brasses are acknowledged for their remarkable resistance to wear, fatigue, and stress corrosion cracking.
