Steel - Pure iron is a relatively soft maleable metal - the addition of small amounts of carbon and other elements during the steel making process add strength and hardness. High strength steels have more carbon than low strength steels, but more carbon also adds brittleness after a point. Silicon, Tungsten and Molybdenum are common alloying elements added to iron to make higher strength steels.
Nylon.
The material will yield when stress reaches a critical value. Stress = Load / Area Thick steel wire is stronger than thin steel wire because there is more cross sectional area in the thick wire. Although the material's strength in load per unit area would be the same, the ultimate load that the wire can sustain would be more in the thick wire. A simple way of looking at it is to imagine a thick wire as a number of thin wires stuck together. If a thin wire can support a mass of 1kg then 2 thin wires can support 2kg. A wire which is twice as thick (twice the cross sectional area) can also support 2kg.

More information is needed really as the answer depends hugely on the application. For example, yes you could tow a friends broken down car with a steel cable of equal strength to the nylon tow rope. ....but not, you could not replace a nylon rope used to moor a boat with (untreated) steel cable as it wuold rust. Nylon rope also has some "give" in it, allowing it to absorb some shock as tension is taken, it is also an excellent insulator. Steel has almost no give at all and is a fairly good conductor (though not brilliant when efficient conduction is required). So it depends massively on your application - all answers from "absolutely not" to "it would be even better" can appy. Mark
Housing uses steel wire
Nylon.
Spiders silk is stronger than steel wire of the same weight. Very fine steel wire is easily broken by hand, but if you could make spider silk of the same weight as normal steel wire it would be much harder to break.
yes
steel reinforced iron
Wire, iron and steel.
To make an electromagnet stronger, you can increase the number of turns in the wire coil, which increases the magnetic field strength. You can also use a stronger magnetic core material, such as iron or steel, to concentrate and enhance the magnetic field.
Iron is considerd to be an alloy steel. This is because an alloy steel is when carbon is the primary alloying element. However, wire of iron is considerd to be a non alloy.
Wire brush or steel wool.
Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.

A wire which is twice as thick (twice the cross sectional area) can also support 2kg.
Three things affect the strength of an electromagnet.The number of turns/wraps of wire.The amount of current flowing through the wire (which is determined by the voltage and the size & kind of the wire).What the core is made of -- the core is the thing the wire is wound around. It will be much stronger if wound around metal than air. Iron makes a better core than most other metals.
Increase the number of coils in the electromagnet. Increase the current flowing through the wire. Use a core material that is easily magnetized, such as iron or steel.
