Copper is a better conductor than aluminum. Two wires with the same cross-sectional area, or any two constructs with the same physical shape and size, one fabricated from aluminum and the other from copper, the one made of aluminum always has higher ohmic resistance.

What is the weight of aluminum conductor as compared to a copper conductor?
Aluminium weighs less than copper for the given volume
Which is harder Aluminium or Titanium?
Bronze. Bronze is an alloy of copper an tin and it replaced copper as the primary metal for tools because the alloy is harder than either of its constituents. Aluminum is softer than copper.
What is an aluminium bronze?
An aluminium bronze is an alloy of copper containing 5 percent to 10 percent aluminium.
What is aluminum and copper's reaction?
Nothing, they simply form a mixture in molten state. A mixture of 10% Aluminium in copper is Aluminium bronze.
What alloy does aluminum iron and copper make?
There are some "aluminium bronze" alloys which contain aluminium copper with a small amount of iron and other metals- these are mainly copper with 4-8% aluminium and ess than 1% of other metals.
What is the weight of aluminum conductor as compared to a copper conductor?
Aluminium weighs less than copper for the given volume
What are the different types of conductors used in transmission?
Overhead transmission lines use steel-cored stranded aluminium conductors. The steel supplies the necessary tensile strength, as aluminium is relatively weak. Copper is not generally used as it is significantly more expensive than aluminium.
Is copper denser than aluminium?
Stainless steel is heavier then aluminium.
Is steel is good conducter of electricity?
Not so good compared to metals such as copper and aluminium. Steel is an alloy where as copper is a pure metal
Why are copper wires used as the connecting wires?
Copper is a metal and as such it can conduct electricity very well. Additionally, copper is a very good conductor off heat when compared to the more abundant metals such as aluminium.
Is romex pure copper?
Copper or aluminium.
Why do you use copper wires in electric wires?
Copper is an excellent conductor, ductile (can be drawn easily), and reasonably economical. For bare conductors, copper oxidises and the oxide coating prevents further corrosion. While it is heavier than aluminum, it is stronger. The alternative, aluminium, is cheaper than copper, but not as good a conductor. Aluminium is lighter, but weaker, and aluminium transmission lines require a steel-core for strength. Aluminium conductors suffer from 'cold flow', which means that aluminium conductors secured with screw terminals tend to work loose over time. Copper doesn't do this, so copper is preferred for residential/commercial electrical wiring systems.
Does copper have aluminum?
Pure copper hasn't aluminium.
Is copper or aluminium a good conductor of electricity?
copper
Which is harder Aluminium or Titanium?
Bronze. Bronze is an alloy of copper an tin and it replaced copper as the primary metal for tools because the alloy is harder than either of its constituents. Aluminum is softer than copper.
What is the effect of copper and aluminium since they metals?
copper and aluminium are metals since their metals the effect is that their good conductors
What is the body of aeroplane made of?
An aeroplane body is made up of an alloy (meaning: mixture of metals) of aluminium and copper. This is as aluminium is very light and cheap, but it needs copper as aluminium is too brittle. This way the plane have a weight of aluminium but the felexibility of copper!
