Performance
NOTE: Aqua Bronze is a patented alloy containing Bi and Sb.  In addition to AQ30 in which Bi=3%, other grades with a modified Bi content are available.  For instance, AQ15 in which Bi=1.5% has been found to be cost advantageous.
Aqua Bronzes mechanical properties, machinability and corrosion resistance is the approximate equivalent to CDA 836 or C83600.   Additionally, it is important to point out that Aqua Bronze an excellent resistance to stress corrosion cracking.

Lead Free - Continuous Cast Bronze has been long identified in numerous studies as a health and environmental concern. Workers can be exposed through inhalation of fumes and dusts, as well as through ingestion as a result of contaminated hands, food, drinks, cosmetics, tobacco products, and clothing. Furthermore, workers can take it home on their clothes, skin, hair, tools, and in their vehicles , potentially exposing their families to harmful health effects. Additionally, approximately 310,000 U.S. children aged 1-5 years have blood lead levels greater than 10 micrograms per deciliter of blood, the level at which CDC recommends public health actions be initiated. Poisoning can affect nearly every system in the body. Because poisoning often occurs with no obvious symptoms, it frequently goes unrecognized. Poisoning can cause learning disabilities, behavioral problems, and, at very high levels, seizures, coma, and even death.

Regardless of its hazard, lit has been a key component of bronze, imparting anti-friction properties, aiding in machinability, etc. Bronze alloys containing pb are found in every industry and every nation.
