I. Material Composition
1. Bronze: usually an alloy of copper, tin, lead and other elements.
2. Brass: is an alloy of copper and zinc. The copper content of brass is higher than 60%, but may also contain a small amount of other materials.
Second, the mechanical properties
1. bronze: bronze is much harder than brass because it contains other elements that increase its tensile strength, wear resistance and hardness. Bronze has high mechanical strength and is suitable for manufacturing processes and mechanical parts.
2. Brass: Brass is softer than bronze and is easy to work and polish. Brass is suitable for making decorations and household items because it can age naturally and produce a surface patina with special beauty.



Third, corrosion resistance
1. Bronze: Bronze is more resistant to corrosion than brass because its alloy composition is more stable. Bronze is often used to manufacture parts for the marine environment, chemical equipment, building structures, etc.
2. Brass: Brass may oxidize and corrode when exposed to fumes, pollutants and other elements. Therefore, it is usually used for decorative purposes, such as the manufacture of brass doors, faucets, and home furnishings.
Bronze and brass have different properties and uses from a number of perspectives, including material composition, mechanical properties, and corrosion resistance. For craft and mechanical parts that require hardness and corrosion resistance, bronze is more suitable; while for household items that require softness, easy processing and good decorative properties, brass is more suitable.
