Aluminum Bronze
Characteristics：
It is a high-strength copper alloy that offers a unique combination of high strength, good fatigue resistance, excellent seawater corrosion resistance, non-sparking characteristics, and wear resistance.
Typical applications:
It is typically used for shells and fasteners in seismic acquisition systems. It is also widely utilized in marine applications due to its unique combination of wear and corrosion resistance.
