Lead processing
Lead-tin. Lead-tin alloys containing up to 98 percent by weight tin are used as solders. The strengths of these alloys increase with higher tin content, while the melting point is lowered to a minimum of 183 °C (361 °F) with a lead content of 38 percent. A half-lead–half-tin alloy is the most common general-purpose solder.
