A complicate question. The hardest metals are certain alloys treated by certain hardening processes, which differ widely. Tungsten carbide is one of the hardest alloys known; any alloy that passes a spec known as Rockwell C-60, is extremely hard, and there is also Case hardening, and other nitriding processes, to name just a few.
Tungsten is the hardest naturally occurring metal on Earth, while copper is one of the cheapest metals that can conduct electricity efficiently. Tungsten is often used in applications requiring high hardness and resistance to heat, whereas copper is widely used in electrical wiring and electronics due to its excellent conductivity.
Tungsten is one of the hardest metals to break due to its high tensile strength and durability. It is commonly used in industrial and military applications that require materials with exceptional hardness and resistance to wear and tear.

There are a range of metals which can be used to make a magnet.
Electrolysis is used in various industrial processes, such as in the production of metals like aluminum and copper, water treatment, and electrolytic refining of metals. It is commonly found in countries with a strong industrial presence, such as China, USA, Russia, and Germany.

Metals are used for the production of screws as they are materials with high hardness and resistance to stress.
Iron, nickel, and cobalt are the most common metals used to make ferromagnets. These metals have magnetic properties that allow them to be easily magnetized and retain their magnetism.

Yes, liquid nitrogen can be used to shrink metals through a process known as cryogenic treatment. When metals are quenched in liquid nitrogen, they undergo changes in their microstructure that can improve their hardness, wear resistance, and overall performance. This process is often used in industries such as aerospace and automotive for enhancing the properties of metals.
Diamonds are used to cut metals because they are one of the hardest materials on Earth. The carbon atoms in diamond form strong covalent bonds, making it exceptionally resistant to wear. This hardness allows diamonds to effectively cut through metals with precision and efficiency.
