A LOT of things...most alloys are lead-free. However...when you see something described as a "lead-free alloy," they're usually talking about a lead-free solder. Soft solder has classically been a mixture of tin and lead due to its low melting temperature and ease of use. Leaded solder is an environmental and health hazard, so people don't want to use it anymore and in many cases CAN'T use it anymore. So...lead-free alloys are used for soldering electrical components and metalwork.
