The advantages of JIS H3300 C6872T Aluminum Brass Alloy
1. Excellent Corrosion Resistance
Seawater Resistance: C6872T exhibits outstanding resistance to seawater corrosion, making it ideal for marine applications such as shipbuilding, offshore platforms, and desalination plants.
Dezincification Resistance: The addition of arsenic (As) in the alloy prevents dezincification, a common form of corrosion in brass alloys where zinc is selectively leached out, leaving a porous copper structure.
Biofouling Resistance: The aluminum content in C6872T provides resistance to biofouling (the accumulation of microorganisms, algae, or plants on surfaces exposed to water), reducing maintenance costs and improving operational efficiency.
2. High Mechanical Strength
C6872T has higher tensile and yield strength compared to standard brass alloys, thanks to the addition of aluminum. This makes it suitable for applications requiring durability and resistance to mechanical stress.
3. Good Thermal Conductivity
With a thermal conductivity of approximately 109 W/m·K, C6872T is an excellent material for heat exchangers and condensers. It ensures efficient heat transfer, which is critical in cooling systems and power generation equipment.
4. Ease of Fabrication
Formability: C6872T can be easily formed, bent, and shaped without cracking, making it suitable for complex geometries in heat exchangers and condenser tubes.
Weldability and Brazability: The alloy can be welded and brazed using standard techniques, allowing for easy assembly and repair in industrial applications.
5. Resistance to Stress Corrosion Cracking (SCC)
C6872T is highly resistant to stress corrosion cracking, a common issue in environments with high chloride concentrations (e.g., seawater). This makes it a reliable material for marine and offshore applications.
