Solder alloy is primarily composed of two main elements: tin (Sn) and lead (Pb).

1. Tin (Sn): Tin is the major component of solder alloy. It has a low melting point and provides the alloy with its ability to wet and bond with the metals being soldered.

2. Lead (Pb): Lead is the second major component of solder alloy. It helps to lower the melting point of the alloy even further, making it easier to work with.

In addition to tin and lead, solder alloy can also contain other elements such as silver (Ag), copper (Cu), antimony (Sb), and others. These are added to improve certain properties of the solder, such as its strength, wetting properties, and resistance to fatigue.

It's important to note that due to health concerns, lead-free solders have become more common. These often use a combination of tin, silver, and copper.
