Aluminum Bronze Supplier | AMS Aluminum Bronze Specifications

Aluminum bronze is a family of copper-based alloys in which aluminum is the primary alloying element. These alloys are known for their high strength, excellent corrosion resistance, and superior performance in demanding environments, particularly where resistance to wear, seawater, and chemical exposure is required.

Aluminum bronze alloys are commonly used in aerospace, defense, marine, and industrial applications where conventional bronzes or brasses do not provide sufficient mechanical strength or environmental durability. Properties vary depending on alloy composition and specification, allowing aluminum bronze to be tailored for specific performance requirements.

Common Applications of Aluminum Bronze

Aluminum bronze alloys are commonly used for:

Aerospace components and hardware
Marine and offshore equipment
High-strength bushings and bearings
Wear-resistant components
Corrosion-resistant fasteners and fittings

The appropriate aluminum bronze specification is selected based on strength requirements, corrosion resistance, and operating environment.

Material Selection and Supply

Aluminum bronze may be supplied in various product forms depending on the governing AMS specification. Material selection is driven by performance requirements and applicable standards rather than alloy family alone.

Tech Steel & Materials supplies aluminum bronze with full material traceability and certifications. Value-added services such as machining support, testing, and specialized packaging are available to meet customer requirements.
