ALUMINUM: Most of the aluminum alloys used today contain some level of lead, usually less than .1%. Lead is known to the state of California to cause cancer and reproductive harm. Most aluminum alloys are physiologically inert in their solid form, and the lead is contained within, however user-generated dust and/or fumes may pose a hazard if inhaled or ingested. Heating beyond a certain temperature may also provide avenues for exposure.
