Ductility is the ability of a material to deform plastically under tension without breaking. Malleability is the ability to deform plastically under compression without breaking.
Ductility and malleability are two terms often used as synonyms. In reality they describe two distinct behaviours of the...

The melting point is one of the most consulted properties in the choice of a material, but also one of the most misunderstood. It's often confused with the maximum operating temperature or with softening. Furthermore, different parameters are sometimes compared, such as the melting point of metals...

What is steel made of? The short answer is: iron and carbon. The complete one opens up a whole world. Steel is a metal alloy composed of over 95% iron, but it's the remaining elements that determine its characteristics.
Understanding the composition of steel means understanding why an S355 behaves...

Elongation at break is one of the main parameters on material test certificates. It indicates how much a material deforms plastically before breaking under load and is a fundamental parameter for assessing its ductility. For the designer it's an essential piece of data: it makes it possible to...

Copper alloys are one of the most versatile groups of materials available to designers: they combine copper’s conductivity and corrosion resistance with mechanical strength and machinability that pure copper could never achieve. There are hundreds of standardised grades, from free-machining brasses...

The tensile test is the most widely used mechanical test in the world for characterising materials. A single test provides the data that every engineer uses on a daily basis: elastic modulus, yield strength, tensile strength and ductility.
In this article, we examine what the tensile test is, how...
