Composition of C68700 Aluminium Brass Pipe
C68700 is typically composed of:
Copper (Cu): The primary constituent, providing strength and good conductivity.
Aluminum (Al): The main alloying element, typically around 7% to 9%. It enhances the material’s resistance to corrosion, particularly in seawater, and contributes to its strength.
Iron (Fe): Present in small quantities, iron improves the material's wear resistance and strength.
Nickel (Ni): Adds to the alloy’s strength, corrosion resistance, and helps improve its performance in marine environments.
Manganese (Mn): Contributes to the alloy’s resistance to oxidation and pitting.
Zinc (Zn): Improves castability and can influence the alloy's strength properties.
The balance of these elements ensures that C68700 aluminium brass offers excellent mechanical properties and outstanding resistance to corrosion, especially in seawater, making it a popular choice in various applications.
