It is a mixture
A reel of solder used for joining electrical circuits together on circuit boards. Solder is made of a mixture of tin and lead and sometimes has has flux (a form of acid) in the core of the solder to ensure a clean surface for the solder to flow into.

usually a mixture of tin and lead metals are used
Solder is typically made of a mixture of tin and lead. Some versions of solder are lead-free and may contain tin, silver, and copper as well.
Tin could be in a mixture with lead to form the solder. Solder is used to hold the components to the printed circuit board.
Solder can be configured with several different types of metals. For instance, silver solder would contain a portion of silver along with another metal. Common electrical solder usually contains a mixture of tin and lead in the ratio of 60/40. That too can vary if the manufacturer wants to make a solder that requires a higher tempreature to melt it.
Solder typically consists of a mixture of metal alloys, such as tin and lead, sometimes with added flux to improve wetting and reduce oxides. The exact composition of solder can vary depending on its intended use and desired properties.
Because it melts easily and is good in a solder mixture to hold wires together.
Solder is a mixture of various metals and elements that have a melting point lower than the metal that is intended to be brazed. Some of these metals are tin, bismuth, lead, and antimony, among others.
This is an alloy, not ionic or covalent.
Solder is a liquid metal alloy that is used to join metal components together when heated and then solidified. It is a eutectic mixture of metals, such as tin and lead, with a low melting point. Solder is commonly used in electronics, plumbing, and metalwork applications.
