Aluminum is very cheap(in terms of aircraft materials) and is very strong for it's weight. It is also very malleable, which means it can bend as apposed to breaking. this is important because if the metal broke, it could expose important things inside the plane such as fuel or passengers.
Primarily aluminum and aluminum alloys.

Yes. Several aluminum alloy's particularly 7075 series
A stronger type of aluminum is used because it is light enough for the airplane to fly and it's very durable
Airplanes are made out of aluminum alloys because weight is such an important factor in aircraft design. Aluminum and aluminum alloys are much lighter than other metals.
Aluminum was first used in airplanes in the early 20th century, with significant adoption occurring during World War I. The lightweight properties of aluminum made it an ideal material for aircraft construction, improving performance and fuel efficiency. By the 1920s and 1930s, commercial aviation increasingly utilized aluminum, leading to its dominance in aircraft manufacturing.

Tine is not commonly used in any substantial percentage in the bodies of airplanes, because metals with higher strength to mass ratios, such as aluminum and magnesium are preferred. Tin could be used for specialty purposes, such as bearings.
Aluminum
Aluminum is used on aircraft instead of steel. This is because the density of aluminum is about 1/3 that of steel (meaning it is lighter). Aluminum is also more ductile than steel, allowing for it to bend or elastically deform without damaging the material.
