The US never made aluminum cents for circulation. You may be thinking of the fact that current (1982-present) cents are made of zinc and coated with copper.
However, there were some experimental aluminum cents struck in 1974 and shown as samples. Supposedly all were melted but rumors persist that a few of them were saved. The coins would have been very unsatisfactory because they looked like dimes and were so light they'd blow away in a moderate wind.
The U.S. still mints pennies, but Canada discontinued them in 2012.
This change happened in 1974. See the related question below for more information.

Due to the rising price of copper, pennies were worth more than face value.
The last year for wheat pennies was 1958.
copper shortage during the war. The us was making pennies out of aluminum during that same period. They made pennies out of steele during WWII. These are known as 'Steelies'
The U.S. started making 1 cent coins in 1793. However, the first pennies (i.e. the coins that are really called pennies, not nicknamed) were minted in England as far back as the 8th century AD.
No, only in the 1970s.
Unless special circumstances dictate an early start, normally the first business day of January of the year in question.
they still make pennies
Only one penny is required, if it is moving fast enough to puncture the hull. If you are talking about the weight of the pennies, then aluminum boats come in various sizes, so they do not all have the same penny carrying capacity. A ten foot long aluminum rowboat can carry a million pennies without sinking. Try it.

Well honey, you've got a dime, two nickels, and five pennies in your piggy bank to make $1.10. So get counting and start making it rain with those coins!
The number of pennies that can fit in an aluminum foil boat before it sinks will depend on the size and shape of the boat, as well as the weight distribution of the pennies. Experimentation would be needed to determine the exact number in each specific case.
An aluminum boat floats due to its hull displacing water, creating buoyant force greater than its weight. By adding pennies, the weight increases, but as long as the buoyant force generated by displacing water is greater than the total weight (boat + pennies), the boat will continue to float.
