When it comes to metals, hardness doesn’t necessarily mean quality. There are other equally crucial properties that have to be considered to determine a metal’s value as a material. In most cases, a balance between flexibility, durability, and what’s needed in a particular application must be achieved to determine if a certain metal is ideal or not.
Two of the most important properties of metal are malleability and ductility. Malleability is the ability of metals to be hammered, pressed, or rolled into thin sheets without breaking, while ductility is the ability of metals to be pulled out into wires. They may seem the same properties, considering that they allow for almost similar kinds of deformation, but they are actually different, although it is also safe to say that most malleable metals are also ductile.
Malleability and Ductility: Not the Same?
One way to differentiate malleability from ductility is by looking at the molecular structure of metals through a microscope. The molecules of a metal consist of packed atoms. Compared to the molecules that make up organic matters, those of metals are highly dense. When applied with stress, these atoms roll over each other depending on the vector forces the stress created. The atoms of malleable metals would normally roll faster. Read more from this article: http://bit.ly/2CKLaoB
