Aluminum Bronze Alloy (C95400 / C95500)
High-Strength Wear-Resistant Copper Solutions by Huaxiao-Alloy
1. What Is Aluminum Bronze?
Aluminum Bronze is a high-performance copper alloy containing aluminum as the primary alloying element, often combined with iron and nickel to further enhance strength and corrosion resistance. This alloy is widely recognized for its exceptional mechanical strength, wear resistance, and performance in corrosive environments.
At Huaxiao-Alloy, Aluminum Bronze is supplied as a structural and wear-resistant metal solution, engineered for heavy-duty, marine, and industrial applications where conventional copper alloys are insufficient.
2. Aluminum Bronze Grades & UNS Numbers
| Grade | UNS No. | Common Designation |
|---|---|---|
| C95400 | UNS C95400 | Aluminum Bronze (High Strength) |
| C95500 | UNS C95500 | Nickel Aluminum Bronze |
Huaxiao-Alloy Engineering Insight:
C95400 is widely used for bushings and wear components.
C95500 offers improved corrosion resistance and toughness, especially in marine environments.
