Ferrum, the Latin, is the root for the modern names for iron in the Italic languages. The word ferrum is possibly of Semitic origin.

: iron —symbol Fe.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.

Uses of iron Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese. These are used to make bridges, electricity pylons, bicycle chains, cutting tools and rifle barrels. Cast iron contains 3–5% carbon. It is used for pipes, valves, and pumps.

He followed Frederick Soddy’s work investigating isotopes and contributed to the discovery of more than 100 isotopes of elements. Using one of Lawrence’s advanced cyclotrons, John Livingood, Fred Fairbrother, and Seaborg created a new isotope of iron, iron-59 in 1937.

From most sewing and quilting applications, a steam iron is the best choice. Quilting fabric is typically made of cotton or cotton blends. Look for an iron that has a dedicated setting for cottons that will smooth out wrinkles to make sewing easier. Compact and lightweight irons are the best irons for travel.

Strength Cast iron has higher strength at reduced costs. They also have higher strength and ductility and are stiffer than pure iron. The strength of cast iron is what makes it a workable material for various industries. It has a low melting point and greater fluidity.

The primary difference between steel and metal is that iron is an element while steel is considered an alloy that comprises both iron and carbon. In general, due to its increased strength properties, steel is used more often than iron in large-scale industries like construction.

By weight, steel contains about 2.14% carbon. Although that’s a relatively small amount of carbon, it results in significant physical changes. Steel, for example, is both harder and stronger than pure iron.

Steel is an alloy of iron and carbon containing less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulphur and oxygen. Steel is the world’s most important engineering and construction material.

However, the density and specific gravity of steel(mild steel/low carbon steel ) and iron are the same almost (7.85 gms/cm3). Hence one is not heavier than the other. However, in case of alloy steels where lot of other metals are added as alloying elements, Steels would be heavier than iron.
