Solder

Definition

A low-melting alloy used to join metal parts, traditionally made from lead and tin.

Used by OCR

Specification C6.1o · Paper 2 (Foundation), Paper 4 (Higher)

Solder is not chosen simply because it is metallic. Its melting point is lower than that of the metal parts being joined. Heating melts the solder so that it flows around the joint; on cooling, it solidifies and holds the parts together.
