Super heroes of metal world

The word "metal" means strength; but strength can be measured in different ways just like superheroes have different powers.

Malleability

Malleability is the ability of a metal to be hammered into thin sheets. Gold and silver are highly malleable. When a piece of hot iron is hammered it takes the shape of a sheet. The property is not seen in non-metals.

Silver is a transition metal. It has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. The metal occurs naturally in its pure, free form, as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. It has long been valued as a precious metal

Ductility/Tensile Strength
Ductility is a solid material's ability to deform when it is pulled from both ends; this is often characterized by the material's ability to be stretched into a wire. Again gold is one of the most ductile metals.

Gold - its a very soft and beautiful metal coveted for thousands of years chemical properties of gold.

Hardness
Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a compressive force is applied.

Titanium is classified as a transitional metal. Titanium is the ninth most abundant element in Earth’s crust. It is almost always present in igneous rocks and their sediments. Pure titanium is a lustrous white metal. It is strong, light with low density, and has excellent corrosion resistance. Titanium is as strong as steel but 45 percent lighter. It is 60 percent heavier than aluminum, but twice as strong.

Toughness
The toughness of a material is the maximum amount of energy it can absorb before fracturing, which is different from the amount of force that can be applied.

Molybdenum is tough metal used in many types of power tools chemical properties of molybdenum.

Corrosion resistance
Corrosion is a process of gradual destruction of metal due to oxygen(process is called - oxidation). 

Zinc is a metallic chemical element. It is the 24th most abundant element in the Earth's crust and has five stable isotopes. Corrosion-resistant zinc plating of steel is the major application for zinc. Other applications are in batteries and alloys, such as brass

Shear strength
Shear strength represents how hard you can try to cut it without it breaking. When you cut a paper with scissors, the paper is failing in its shear strength.

iron is used to make an alloy called "steel" which has very high shear strength.
