Aluminum Bronze-Spherical

Aluminum bronze is a copper-based alloy of which aluminum is the main alloying metal added to copper. The aluminum adds strength, corrosion resistance, hardness, resistance to wear and galling, low magnetic permeability, resistance to cavitation, erosion, softening, and oxidation at elevated temperatures. Aluminum bronze also offers an ease of weldability. These spherical aluminum bronze powders offer excellent packing density, low viscosity mixing, and predictable flow rates.
Typical Chemical Analysis

ALUMINUM 9.0–10.5%
IRON 0.70- 1.50%
OTHERS, Max. <0.50% COPPER Balance

Available Grades

AB200 (75% min. -325 Mesh)
AB300 (99% min. -325 Mesh)

Typical Applications

Aluminum bronzes are commonly used in applications where their resistance to corrosion makes them preferable to other available materials. They have applications in seawater-related engine components and underwater fastenings, aircraft bushing and landing gear components, jewelry, and tools for use in non-sparking environments.

Packaging Options

Jars, pails, drums, multi-ply paper bags, bulk bags, and fiberboard containers
