Weight of tin, specific weight of tin and its characteristics
Tin is a silvery-white metal with good plasticity, malleability and a relatively low melting point. In everyday use and industry it is valued for corrosion resistance, its ability to form alloys, and its suitability for tinning, soldering and protective coatings. The main physical characteristics of tin are shown in the table.
| Physical characteristic | Value | Unit |
| Density / specific weight of tin | 7.28 | g/cm³ |
| Weight of 1 m³ of tin | 7280 | kg |
| Melting point | 232 | °C |
| Boiling point | 2602 | °C |
| Thermal conductivity | about 66 | W/(m·K) |
| Linear thermal expansion | about 0.000021 | 1/°C |
| Elongation | up to 80 | % |
An important feature of tin is its ability to change from the white metallic form to gray tin at low temperature. This transformation can occur below 13.2 °C and is accompanied by a change in the material structure. White tin is a metal, while gray tin has different properties and a much lower density.
Tin melts at a relatively low temperature, which makes it convenient for soldering and coating. Its thermal conductivity is lower than that of many common metals. When processing and stamping tin products, it is important to consider the softness of the metal, its plasticity and noticeable thermal expansion. Because of its malleability, tin can be rolled into thin sheets and foil.
Interaction of tin with other substances
When interacting with other metals, tin can form alloys. Such alloys are widely used in industry, soldering, protective coatings and production of various technical products.
The influence of several substances and environments on tin is shown below:
| Substance or environment | Influence |
| Air | Under normal conditions tin is stable due to a protective oxide film. |
| Dilute acids | Dissolve tin slowly; the rate depends on acid composition and temperature. |
| Concentrated sulfuric acid | Can dissolve tin faster, especially when heated. |
| Nitric acid | Oxidizes tin and forms tin compounds, including metastannic acid. |
| Water and salt solutions | Tin is usually fairly resistant, but long exposure to aggressive media can cause corrosion. |
Tin is widely used in technical production. It is used for tinning iron and copper products, creating corrosion-resistant coatings, making solders and producing electrical components. Due to the relative chemical stability and low toxicity of metallic tin, it is also used in coatings for food containers and some piping systems.
Frequently Asked Questions
Can the density of tin be used for precise calculations?
The density and weight values for tin in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of tin differ from the table?
The actual weight of tin depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of tin from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of tin is given in kg/m³ and the volume is in m³, the result will be in kilograms.
