Heavy metal refers to a metal whose specific gravity is greater than 5. It generally refers to a metal whose density is greater than 4.5 grams per cubic centimeter, and it also refers to a metal whose atomic weight is greater than 55. For example, iron has an atomic weight of 56 that ...
The lightest or least dense metal that is a pure element islithium, which has a density of 0.534 g/cm3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water. ...

In our eyes, for sintering to be considered high-temperature, it needs to happen at around 100-250 °F hotter (in the case of iron-heavy materials) than the standard sintering temp for a particular metal. For iron-heavy metals, the typical temperature is 2050 °F. High-temp sintering is...
