Tin Bar

Formula: Sn

Form: Bar

Material: Tin

CAS Number: 7440-31-5

Commodity: Metals

Goodfellow’s Tin Bar is a versatile choice for engineers that’s available in 6 variations. Its low melting point (232°C), malleability and ductility make it ideal for soldering and joining metals. Additional properties include high corrosion resistance and the ability to form alloys with other metals. In aerospace, tin is used in high-reliability electronics assembly and as a coating for components, enhancing wear resistance, corrosion protection and thermal conductivity. Tin alloys also serve as structural materials due to their high strength-to-weight ratio and good fatigue performance.
