Mostly from cast aluminium.
The crankcases of a 2005 Suzuki RM250 are typically made of aluminum. This lightweight material is favored for its strength and durability, which are essential for handling the stresses of high-performance motocross riding. Aluminum also helps in reducing the overall weight of the bike, contributing to improved handling and acceleration.

Some of them are made of chrome molly but I'm shure there are other compositions as well.
Piston rings are commonly made from cast iron or steel, with coatings such as chrome or plasma molybdenum for added durability and longevity. These materials help provide a tight seal between the piston and cylinder wall, reducing oil consumption and improving engine performance.
* Most of the current fleet of aircraft is composed primarily of aluminum. * In the early days aircraft were made from canvas stretched over a wooden frame & then painted. * Some new aircraft are made of fiberglass or carbon composites. * Some small aircraft are composed of an aluminum frame with mylar stretched over in the same way wood and canvas was used.
Most of aircraft fuselages are made of aluminium alloys
Made upof Hypereutectic alloy... Hypereutectic alloy is a combination of aluminum and silicon
Depending on the aircraft, the wings can be made of Steel (Only older planes), Wood (REALLY old planes), Aluminum (Common today), Or Carbon Fiber (used in Military jets)
Aircraft are made of many different material's. the body and wings of an aircraft are usually made of a copper aluminum compound which has been age hardened to cope with the forces seen during flight. As technology advances we are now seeing aircraft being built of carbon fibre. Currently the only carbon fibre aircraft being produced is the 787 dreamlinerThey are usually made from Aluminum Alloys - Because it is light and strong :)A lot of planes are made of aluminum to make the shassie as light as possible. Butsome are made of steel.
Crankcases are typically made from materials like aluminum alloys, cast iron, or magnesium. Aluminum is favored for its lightweight and good thermal conductivity, while cast iron offers strength and durability. Some high-performance applications may use magnesium for its even lighter weight. The choice of material often depends on the engine's design, performance requirements, and manufacturing considerations.
