Tin is a soft, shiny, malleable metal that resists corrosion. It’s used in alloys with other metals, such as combining tin and copper to make bronze. Tin is used in the manufacturing of glass and for making solder and car parts.

Because pure tin is relatively weak, it is not put to structural uses unless alloyed with other metals in such materials as bronzes, pewter, bearing metals, type metals, lead-based solders, bell metal, babbitt metal, and low-temperature casting alloys.

Cheaper, lighter and recyclable, aluminum rapidly overtook tin and steel. But tin still has its uses. A tin/lead alloy is used to make solder. Copper and other metals are mixed with tin to make pewter, which was once a common metal for tableware.

Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers. The earliest known metals—common metals such as iron, copper, and tin, and precious metals such as silver, gold, and platinum—are heavy metals.

Tin has many uses. It takes a high polish and is used to coat other metals to prevent corrosion, such as in tin cans, which are made of tin-coated steel. Alloys of tin are important, such as soft solder, pewter, bronze and phosphor bronze. A niobium-tin alloy is used for superconducting magnets.

Weigh the piece of metal, and then get its volume by putting it in a known volume of water and watching how much the water rises when you put the metal in. The density is mass (g) divided by the volume (mL). If the density is around 3, it should be aluminum. If the density is near 7, it is tin.

Some common methods are surface appearance, spark test, chip test, magnet test, and occasionally a hardness test. Sometimes you can identify a metal simply by its surface appearance.

Magnetism. Iron, steel, tin and aluminum are paramagnetic materials — so regardless of the composition of your “tin” can, it will be attracted to a magnet.

These materials can become magnetized when exposed to an external magnetic field, and consequently attracted to a magnet….MagneticMaterialsChecklist. pdf.

The most common metals used for permanent magnets are iron, nickel, cobalt and some alloys of rare earth metals.

How to Tell Which Cans Are Aluminum

1. Place a magnet onto a can. If the magnet sticks to the metal, it is not aluminum.
2. Hold the can in your hand and feel its weight and durability.
3. Check the bottom of the can that you are investigating.
4. Feel and look at the body of the can.

In the past, the instability of this region has led to price spikes in tin. Essentially no tin is mined or smelted in North or Central America. Tin’s price per pound is about 3 to 5 times that of base metals such as zinc, lead, and copper, yet it is much cheaper than precious metals such as silver, gold, and platinum.

Tinfoil is made of tin. Aluminum foil is made of aluminum. Tinfoil tends to rub off on what it is wrapped around much more so than aluminum, so people who wrapped their food in tinfoil would be eating (small amounts of) tin as a result. Tin isn’t very dangerous, but it isn’t a pleasant taste.

Aluminum has replaced tin in industrial applications, such as for cans. Tin is considered to be toxic to humans, and so is aluminum, but not inherently toxic. Aluminum is a good conductor of heat and energy when compared to tin, which is better than ceramic, etc, but not better than aluminum.

Because inorganic tin compounds usually enter and leave your body rapidly after you breathe or eat them, they do not usually cause harmful effects. However, humans who swallowed large amounts of inorganic tin in research studies suffered stomachaches, anemia, and liver and kidney problems.

Aluminum foil, also called tin foil, makes an excellent insulator, and in some situations, it works better than materials like cotton or paper. Aluminum foil is not best for every situation, though, so using it correctly is an important part of saving energy.

While other tin-free alloys — including tin-copper, tin-silver, tin-bismuth and tin-zinc — can be used as an alternative to tin-lead, pure tin is viewed as a better choice over each of these options. Plating with pure tin is simpler and more cost-effective than when using any of the tin alloys.

How Are Tin Alloys Used Today? Common modern alloys which tin is a significant component of include pewter and solder. Pewter is used to make tableware, trays, decorative ornaments and other household items. Solder is used to create a permanent bond between metal pieces, like wires in a circuit board.

Solar technology, electronics, soldering and brazing, engine bearings, medicine, cars, water purification, jewelry, tableware, and your precious metals portfolio—silver can be found practically everywhere.

It is used for jewellery and silver tableware, where appearance is important. Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries.
