How much aluminum is in a 747?
How much aluminum is in a 747?
Take the Boeing 747-400, for example. According to a post in the Science-Based Life blog, the 747-400 consists of 147,000 pounds (66,150 kg) of high-strength aluminum. That’s almost 75 tons of aluminum (along with 171 miles (274 km) of wiring and 5 miles (8 km) of tubing!)
IS 747 made of aluminum?
The modern Boeing 747 is an aluminum airplane as well. Other metals, such as steel and titanium, are sometimes used to build aircraft. Steel is heavy though, so not too much is used.
How many knots does a 747 need to take-off?
What speed does a Boeing 747 take off at? A fully loaded Boeing 747 ‘Jumbo Jet’ on a normal long haul flight would take off at a speed of around 160 knots which is 184 mph. The calculated take-off speeds vary depending on environmental conditions, runway length and weight.
What are the specs of the Boeing 747?

How much aluminum is in an airplane?
It has higher strength, such as steel, and is more prone to stretch than heavy metals. A boeing 747-400 type airplane with 6 million parts, 71 meters long, 64 meters wingspan and 270 kilometers of cable, weighs approximately 185,000 kilograms, of which approximately 75,000 kilograms is aluminum.
What is the scrap value of a Boeing 747?
Once a jet has been stripped bare of usable parts, its metal frame is redeemed for scrap value. A 747 can fetch up to $55,000 for its scrap alone.
What grade of aluminium is used in aircraft?
Grade 2024-T3 is the most common high-strength aluminum alloy. It is often considered aircraft quality. It has excellent fatigue resistance even though its corrosion resistance is lower than that of 6061.
At what speed does a 747 lift off?
| Aircraft | Takeoff Weight | Takeoff Speed |
|---|---|---|
| Boeing 757 | 240,000 lb 108,860 kg | 160 mph 260 km/h 140 kts |
| Airbus A320 | 155,000 lb 70,305 kg | 170 mph 275 km/h 150 kts |
| Airbus A340 | 571,000 lb 259,000 kg | 180 mph 290 km/h 155 kts |
| Boeing 747 | 800,000 lb 362,870 kg | 180 mph 290 km/h 155 kts |
How much HP does a 747 have?
The hp of every plane can vary. According to calculations, while the jet engine of a Boeing 777 has a horsepower of 30,843, the jet engine of a Boeing 747 has a horsepower of 59,934.
How much aluminium is in a 737?
80% aluminium
Indeed, the very popular Boeing 737 consists of 80% aluminium. Virtually no part of a plane that can be substituted with aluminium is spared in the modern era with parts such as the fuselage, the wings, the doors, the floors, and the seats, now all being made of aluminium.
What is the difference between 6061 and 7075 aluminum?
Both 6061 aluminum and 7075 aluminum are heat treatable. It is interesting to note that even though 7075 aluminum is much stronger than 6061 aluminum, it melts at a slightly lower temperature. Because 6061 aluminum has a higher thermal conductivity than 7075 aluminum, it can be a better choice for certain applications.
Can a 747 fly faster than the speed of sound?
A fluke storm system sped up international flights to record-setting speeds. The flights were faster than the speed of sound, but didn’t break the sound barrier because of surrounding wind speed. The top speed for a 747 is about 570 miles per hour (mph), and this flight topped out at 825 mph.
