Electricity i.e. a battery, can be made by taking two different metals (maybe that's where your confusion came in) - for example, copper and zinc, and submerging them into a an acid solution (like vinegar).
Or you can take those same to metals and stick them into a lemon.
If you put a volt meter on the two different metals you will measure a small, but noticeable, current.
But to answer your queston, you will not make electricity by rubbing two pieces of metal together.

Human needs for mining minerals?
If it was not grown, it was mined. Metals and minerals come from mining. The computer you are using to read this was made with minerals and metals from mining. The wire that carries electricity to your house came from mining (much of the electricity came from mining too).
Why are switches made of plastic and not metal?
metals are good conductors of electricity. plastic and wood are insulators. they do not conduct electricity
Are alloys conductors of heat and electricity?
yes, all alloys do conduct electricity due to the conductivity of their metals.
What solid that is a good conductor can be made into ornaments?
Metals are good conductors of electricity and are sometimes made into ornaments.
Why are electrical wires made with metals chemical bonds?
It's partly a convention of terminology; similar items are made from plastic or fabric and they are called "string" or "strands".You may be asking why metals are used for electrical wiring; that's because metals are conductors - that's almost a definition of what a metal is - metallic elements have surplus electrons and conduct electricity.

How do you distinguish a metallic and a non metallic by using 5 properties?
metals are shinier than some of thenon metals. metals are excellent conducters of heat and electricity. metals can bear alot of strain without breaking. metals can be made into thin wires. metals can be mae into thin shapes.
Why do conductors conduct electricity while insulaters don't?
Conductors conduct electricity because most of them are made of metals and metals are good conductors of electricity while insulators are made of rubber and rubber does not conduct electricity. To conduct electricity, the atoms that make up the material, have to have free electrons that can pass a charge on. Metals have these free electrons, whereas insulators do not.
What are wires made from?
Wires are made form many differant types of copper and othe metals. Why is this it is because electricity is atracted to metals
Are coins good or poor conductors of electricity?
Coins are made of metal and metals are good conductors of electricity.
How do you make eletricity from fruit and vegetables?
Fruit can produce electricity by puting an anode and a cathode in them preferably made from different metals join them to a wire and you will have a current.
Why are switches made of plastic and not metal?
metals are good conductors of electricity. plastic and wood are insulators. they do not conduct electricity
Are alloys conductors of heat and electricity?
yes, all alloys do conduct electricity due to the conductivity of their metals.
What solid that is a good conductor can be made into ornaments?
Metals are good conductors of electricity and are sometimes made into ornaments.
Why are pans made from different metals?
because different metals are better and worse heat conducters
How electricity made by pencils?
Electricity is not made by pencils: Electricity can pass through pencils since they are made using graphite which is a good conductor.
Why switches are made of plastic or bakelite and not metals?
Switches are made of plastic or bakelite because they don't conduct electricity.
