iron and aluminum are useful metals made from alloy
Aluminum, itself, is not an alloy. You may be referring to an aluminum alloy, which is a mix of two metals(often aluminum and steel) intended to combine their characteristics. Aluminum is one of the base metals.
ionic cause its a compound made of metals and non metals
The fact that they are made from metals.
The word "Ferrous" indicates "Iron". Ferrous metals are metals which are made up of iron. For example, Carbon steel, Wrought iron, Stainless steel and Iron itself. Non-ferrous metals on the other hand are metals which do not have any iron content in them. For example, Nickel, Lead, Brass, Copper, etc.
One is oxidized aluminum and the other is oxidized iron. Iron oxide is magnetic. Aluminum oxide is not. Most of the clear semi precious gems like rubies and emeralds are made from aluminum oxide. Iron oxide is in hematite the black, opaque mineral.
Engines can be made out of iron, steel and aluminum. Aluminum is lightweight, but is not as durable as the formerly listed metals.
Steel, Aluminum, Zinc, Iron, Brass, & Copper
Aluminum foil is a type of metal. Steel, iron, copper, aluminum.. all of those are metals.
. Examples of hard magnets are Aluminum-Nickel-Cobalt (Alnicos) and Strontium-Iron (Ferrites, also known as Ceramics).
Aluminum is a light metal. Found almost exclusively in the crust. The heavier metals are found in the core, which is mostly made up of iron.
aluminum .... iron you plonk

Kinda obvious :S Metals (usually aluminum or steel) are used in cars because they are strong and cheap. Expensive sports cars usually have stronger metals (like titanium) but that makes them more expensive. Different metals are used for different purposes, too. The main frame of a car would usually be steel instead of aluminum because it is stronger but delicate pieces would be made of aluminum because strength is not needed but it would be cheaper to make them in aluminum
Anything made of iron and iron's alloys are called ferrous. For example iron nails, steel bolts, nuts and other steel parts, etc. Metals other than iron and its alloys are called non-ferrous, like brass, copper, lead, aluminum, etc.
Iron or Nickel metals and Iron sulphides.
Alloys are "mixtures" of metals or non-metals in metals. They are developed to create new characteristics of the metals. Carbon (and other things) added to iron makes steel. Precise mixtures makes different sorts of steel alloy. Steel is stronger than iron and can have many characteristics which give superior properties for specific purposes. There is a virtual infinite number of alloys which could be made. Not all will have useful characteristics.
The cans containing iron are magnetic, the aluminum ones aren't.
