Stainless steel, also known as inox or corrosion-resistant steel (CRES), is an alloy of iron that is resistant to rusting and corrosion.

Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight.

Nickel will alloy readily with many other metals, including chromium, iron, molybdenum and copper.

Copper is a soft, malleable and ductile metal with very high thermal and electrical conductivity.

Special steels have higher strength and toughness, physical properties, chemical properties, biocompatibility and processing capabilities than ordinary steel.
