Mechanical properties
Mechanical properties depend on the heat-treatment condition and the ordering specification and are therefore not listed as single values. They are agreed per project.

Casting and processing considerations
Aluminium bronzes form tenacious oxide films, so turbulence-free filling is essential to avoid oxide inclusions. Leaded alloys are restricted in drinking-water and some regional applications; the applicable regulations should be checked before an alloy is specified. Listed strength values originate from sand-casting specifications and are indicative for investment castings.
