Admiralty Brass is a popular copper alloy known for its excellent resistance to corrosion, durability, and thermal conductivity. It is widely used in marine applications, heat exchangers, and industrial piping systems. This blog explores its composition, key properties, and industrial uses.
Composition of Admiralty Brass
Admiralty Brass consists primarily of:
- Copper (Cu): 70%
- Zinc (Zn): 29%
- Tin (Sn): 1%
The presence of tin enhances resistance to dezincification, ensuring longevity and durability in corrosive environments.
Key Properties of Admiralty Brass
- High Corrosion Resistance: With added tin, the alloy effectively resists dezincification and seawater corrosion.
- Superior Thermal Conductivity: Ideal for heat exchangers and cooling systems.
- Mechanical Strength: Provides excellent strength while maintaining workability.
- Antimicrobial Properties: Copper content helps prevent bacterial growth.
- Aesthetic Appeal: Its bright golden hue is desirable for decorative applications.
