CuAl9

An aluminium bronze alloy for high-quality surface finish and aesthetic applications

Ideal for high-quality surface finish

CuAl9 is an aluminium bronze alloy particularly valued for applications where surface appearance and finish quality are essential.

Its excellent castability allows the production of complex parts with clean, smooth and homogeneous surfaces. Once polished, it offers a distinctive golden color similar to brass, making it suitable for both technical and decorative applications.

Lead-free and zinc-free, CuAl9 represents a durable and reliable alternative to traditional alloys, combining aesthetic quality with good mechanical performance.

Mechanical properties of CuAl9

Tensile strength: ~500 MPa
Yield strength: ~180 MPa
Elongation: ≥ 20%
Brinell hardness: ~100 HB

Performance and finishing capabilities

CuAl9 provides a good balance between mechanical strength and ease of finishing. Its excellent polishability makes it ideal for components requiring a high-quality surface finish.

It maintains its mechanical properties over time and performs reliably in industrial environments, while offering good corrosion resistance.

Aluminium bronze alloys also retain their mechanical properties at low temperatures without embrittlement and can be used in applications requiring consistent performance.

CuAl9 can be supplied in various conditions: as-cast, polished, painted or surface-treated (nickel plating, chrome plating, gilding).

A versatile alloy for high-quality finishes

CuAl9 combines good mechanical properties with excellent finishing capabilities, making it a preferred choice for applications where aesthetics and durability are equally important.

Its good corrosion resistance and ease of processing allow reliable production of both functional and decorative components.
