Potential advantages include:

Smooth appearance after appropriate finishing processes.
Compatibility with multiple plated or coated finishes.
Versatility for residential and commercial interior hardware ranges.
Aluminum alloy provides an alternative material option for architectural door handles requiring relatively lightweight construction and a contemporary metallic appearance.
Potential advantages include:
Lower material density than zinc alloy.
Suitable for modern hardware designs.
Can be finished using compatible surface treatment processes.
Useful for material-specific OEM product development.
