How Do You Make a List of Soft Metals?

On the Mohs hardness scale, lead, gold, silver, tin, zinc, aluminium, thorium, copper, brass, and bronze are all soft metals. Gallium melts at 85.57 degrees Fahrenheit, so it could also be called a soft metal. Mercury is a metal, and at room temperature, it is a liquid.

Often, the softness of a metal is what makes it valuable. Copper is soft, so it can be shaped into thin wires and both flexible and rigid plumbing pipes. Copper is too soft to use for other things, but it can be mixed with other metals to make brass and bronze, which are a little stronger.

Lead can also be used to make plumbing pipes, and some of these pipes have been in use since the time of the Roman emperors. One reason for this is that lead is so soft that it can be easily fixed by hammering or applying molten lead. Lead can be melted over a regular fire because its melting point is about 621 degrees F.

For other metals, being soft is a bad thing. People think that soft precious metals like gold and silver are too weak to wear every day, so they are almost always mixed with another metal to make them stronger.
