∙ 12y agobecause of the random gaps in the aluminum therefore the atoms slip and it bends rather than breaks.

Why are alloys so strong?
Alloys are so strong because they will take properties from both metals, such as when you alloy Titanium and Aluminium. Aluminium will get stronger because the forces that titanium once used to attract each other is now used to attract the aluminium
Which element is strong and lightweight?
Aluminium
Why is the frame on a bike made out of alloy and not pure aluminium?
Aluminium alloys are stronger than pure aluminium, which is comparatively soft. Pure aluminium is also considered chemically reactive (thus the layer of aluminium oxide which coats the metal due to oxidation). Pure aluminium hardly exists due to its strong affinity with oxygen in air. In fact, aluminium foils and beverage cans are also alloys of aluminium, with about 92 to 99% of aluminium. So likewise, bike frames are also made of alhminium alloys because of its characteristics of being strong and lightweight.
A metal that is strong at high temperatures and resists corrosion?
It is out of aluminium,gold,chromium and titanium.
Why is aluminium metal good?
It is strong and dense, weighs light and is a good conductor

Why are the wheels on an aeroplanes made of aluminium?
Most aircraft wheels are made of aluminium alloys. They are light and strong.
A metal that is strong at high temperatures and resists corrosion?
It is out of aluminium,gold,chromium and titanium.
Why do they use aluminium on cars?
It's light and strong.
Why is aluminium used for aeroplanes?
Because it is light and strong.
What elements in in aluminium?
Aluminium is actually an element, so the only element in aluminium is aluminium.
Is Na2CO3 as strong or weak electrolyte?
Aluminium carbonate is a weak electrolyte.
Why do you use aluminium for greenhouses?
Because it is strong, light and will not rust.
What are some lightweight and durable materials?
Aluminium and Titanium Extruded polystyrene is about as strong as unalloyed aluminium, but much more flexible and much lighter.
Why iron structures need protection from corrosion while aluminium structure do not?
Because aluminium oxide is strong and forms a coating over the aluminium, whereas iron oxide (rust) flakes away.
