duralumin, copper is added to the aliminium to make duralumin
they are very strong and durable.
An alloy of Magnesium is a type of steel with Magnesium as the main ingredient. For example, Magnox is 99% Magnesium and 1% Aluminium is a steel used for the cladding of fuel rods in some nuclear power stations. Another alloys with Magnesium contain Aluminium, Zirconium, Silver, Zinc, and the Rare Earth Elements such as Yttrium and Erbium.
Almost any metal might be included in a steel alloy. The simplest alloy that is called steel is an alloy of just iron and carbon. But it is the ratio that is important (e.g. cast iron is also an alloy of just iron and carbon, but it has too much carbon making it too brittle to be steel). There are also a few nonmetals (e.g. boron, silicon) that might be included in a steel alloy.
Chemically, aluminium is an element, while steel is an alloy consisting mostly of iron. Although most aluminium items you see and use are also Alloys, strictly speaking. Steel is stronger but heavier. They have quite different material qualities.
The alloy of steel is carbon and iron.
Depending on the rocket it could be made of an aluminium alloy, a steel alloy or titanium.
Either steel, an iron-based alloy, or some sort of aluminium-based alloy.
steel
Because aluminium is not only cheaper but lighter. - Dave! Yognaut
Combination of strength, weight, durability, and cost that goes into make something. Steel is strong, but really heavy. Aluminium is light, but not very strong. Also, some metals make the alloy not rust. An example is Stainless Steel. Its a combination of Steel and Chrome. The Chrome makes the Stainless steel cost more. Its an Engineer's job to find the best alloy for the job.
they are very strong and durable.
In several places actually. Fasteners - screws, nuts and bolts - are usually steel. Wheel axles, freewheel mechanisms, brake parts tend to be steel. Aluminium forks may have steel steerers. Bearings tends to use steel.
Usually an aluminum alloy, although high-end ones may be of titanium.
Generally motorcycle blocks are made of either cast Iron, or Cast Aluminium. A lot of custom metals are available for the highest end race teams, but odds are if you run into a modern dirt bike, the block will be cast aluminium, the pistons will be a steel alloy, the crank will be either cast iron or a steel alloy, and the Connecting rods (between the pistons and the crank) will be either a steel alloy, or an aluminium alloy. Possibly titanium in various percentages in any or all components. Older engines will be generally the same, but the block will be more than likely made of cast iron.
Not so good compared to metals such as copper and aluminium. Steel is an alloy where as copper is a pure metal
