Metal is one of the earliest materials used by mankind to support several sectors starting from construction to technology. The use of metals which are categorized under chemical elements having metallic properties has variously defined properties that have over many centuries molded society and Touched civilization from the Stone Age to the contemporary age. It has shocked me how they are strong and at the same time ductile, good conductors of heat, and admit alloy formation, thereby making them suitable for seemingly endless uses. Here we will discuss about 24 types of metals and their peculiarities to reveal how versatile this material is.
What are Metals?
Metal as an element or compound is majorly characterized by certain qualities including high electrical and thermal conductivity, ductility, and ability to alloy. They are usually lustrous and have a metallic density at room temperature for most of them are metals except for mercury. Metals are parent metals that are widely available in the earth’s crust in a combined form with other elements known as ores which are mined and purified for their use in industrial applications. It can forge multiple linkages and can be designed into commodities.
What is Ferrous Metal?
Ferrous means largely made up of iron and is one of the strongest groups of metals. Under normal conditions and when exposed to moisture and air they rust or corrode unless protected or made into an alloy. They include; steel cast iron. These metals are used commonly in building construction, in the automobile industries as well as in Manufacturing industries.
What is Non-Ferrous Metal?
Nonferrous metals are those metals that are not mixed up with iron or have limited qualities of iron contained in them. These are generally more hard-wearing against corrosion and oxidization than Ferritic metals and are lighter in weight, more ductile, and possess superior electrical and thermal conduction characteristics. These include aluminum, copper, lead, zinc, gold, silver, and titanium and many others can also be mentioned here. Common uses of non-ferrous metals include aerospace industries electric industries and the manufacture of jewelry.

FAQs
What are ferrous metals and what are non-ferrous ones?
Ferrometals contain iron and are susceptible to rusting while non-ferro metallics metals do not contain iron and therefore are not susceptible to rusting as much as ferro metallics.
Why are non-ferrous metals chosen for use in aerospace?
The ferrous and non-ferrous materials – aluminum and titanium – are mild, lightweight, have high resistance to corrosion, and are strong materials suitable for aerospace use.
How can rusting on ferrous metals be prevented?
As it directly reacts with air, avoid using iron and steel or paint it, use protective coatings, or use alloys that are free from rust or regularly overhaul it.
Can all the non-ferrous metals be recycled?
Yes, such materials as aluminum and copper are easy to recycle, and using them preserves many resources.
