Question

Name two alloys of iron. What elements are present in these alloys?

Answer 1

Answer:

Cast irons, alloys of iron, carbon, and silicon, contain carbon as graphite (pure carbon), as carbide (Fe3C), or in solid solution in austenite (austempered ductile iron (ADI), matrix austenite with 1.7–2.1% carbon).

Explanation:

Iron is a great building material but steel (an alloy made by adding small amounts of nonmetallic carbon to iron) is stronger, harder, and rustproof. Aluminum is a very light metal but it's also very soft in its pure form.
