Aluminium vs. Tin — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on May 8, 2024
Aluminum is a lightweight, corrosion-resistant metal commonly used in construction and packaging, while tin is a softer, corrosion-resistant metal primarily used to coat other metals to prevent rust and in food packaging.

Key Differences
Aluminum is a lightweight, silvery-white metal known for its high strength-to-weight ratio, making it ideal for construction, transportation, and packaging. Tin, on the other hand, is a softer, silver-colored metal known for its corrosion resistance, commonly used as a coating on other metals.
Aluminum is more abundant and recyclable than tin, making it a cost-effective material for mass production. Tin, however, is scarcer and often used as a protective layer in the production of tinned steel or alloys.
Aluminum’s non-corrosive properties and lightness are suitable for manufacturing beverage cans and automotive parts. Tin is traditionally used in food packaging due to its ability to prevent rusting, though its use has declined in favor of alternatives.
Aluminum reacts with air to form a protective oxide layer that prevents further corrosion. Tin forms a similar protective layer but is often combined with other metals to enhance its resistance.

Tin
Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue.
Aluminium
A light, silvery metal extracted from bauxite, and a chemical element (symbol Al) with an atomic number of 13.
Tin
Symbol Sn A crystalline, silvery metallic element obtained chiefly from cassiterite, and having two notable allotropic forms. Malleable white tin is the useful allotrope, but at temperatures below 13.2°C it slowly converts to the brittle gray allotrope. Tin is used to coat other metals to prevent corrosion and is a part of numerous alloys, such as soft solder, pewter, type metal, and bronze. Atomic number 50; atomic weight 118.71; melting point 231.93°C; boiling point 2,602°C; specific gravity (gray) 5.77, (white) 7.29; valence 2, 4. See Periodic Table.

Tin
An elementary substance found as an oxide in the mineral cassiterite, and reduced as a soft silvery-white crystalline metal, with a tinge of yellowish-blue, and a high luster. It is malleable at ordinary temperatures, but brittle when heated. It is softer than gold and can be beaten out into very thin strips called tinfoil. It is ductile at 2120, when it can be drawn out into wire which is not very tenacious; it melts at 4420, and at a higher temperature burns with a brilliant white light. Air and moisture act on tin very slightly. The peculiar properties of tin, especially its malleability, its brilliancy and the slowness with which it rusts make it very serviceable. With other metals it forms valuable alloys, as bronze, gun metal, bell metal, pewter and solder. It is not easily oxidized in the air, and is used chiefly to coat iron to protect it from rusting, in the form of tin foil with mercury to form the reflective surface of mirrors, and in solder, bronze, speculum metal, and other alloys. Its compounds are designated as stannous, or stannic. Symbol Sn (Stannum). Atomic weight 117.4.
