Steel and plastic, these two materials are essential for much of our infrastructure and technology. Both have stengths and weaknesses. Steel makes the world, from the tinest pin in a sewing kit to home appliances to cars and bridges. Its strength is unparallel , so much so that Superman is called the 'Man of steel' . Steel is strong and hard, but difficult to shape intricately. Plastic is known for its flexibility. So, wouldn't it be nice if one material was as strong as the steel and shapeable like plastic. This is where metallic glass comes into the picture. It is a combination of wi both of these properties and more. They are shiny and opaque like metals and also like metals they conduct heat and electricity. But they are way stronger than a lot of metals, which means they can withstand a  lot of force.

They also have an incredible ability to store and release elastic energy. What is elastic energy? Elastic energy is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape.Elastic energy occurs when objects are compressed and stretched, This makes them perfect for sports equipment like tennis racquets etc.

Unlike other metals they are resistant to corrosion. They are strong at room temperatures, but at higher temperatures they can be changed into any shape you like. This has to do with metalic glasses unique atomic structure.



Metallic glasses typically contain four or five elements, such as zirconium, titanium, copper, nickel, aluminum, platinum, iron and others. However, it is the main element that determines the cost and application. Zirconium-based metallic glasses, for example, exhibit high strength and elasticity, and may be used in sporting goods or military applications, while titanium-based metallic glasses may be considered for precision medical tools because of their biocompatibility.
