What happens when aluminium reacts with iron oxide and where is this reaction used?
When aluminium reacts with iron oxide, a thermite reaction occurs, producing aluminum oxide, iron, and a large amount of heat. This reaction is used in welding and metal cutting applications due to the intense heat generated.
Why can't aluminium be extracted the same way as iron?
Aluminium is more reactive than iron, making it harder to extract using traditional methods like reduction with carbon. Instead, aluminium is extracted through electrolysis of alumina, a process that requires high temperatures and produces pure aluminium.
What metal is the best conductor of heat aluminium iron or brass?
Aluminum have better thermal conductivity than ironAluminum: 205W/(m K)Iron: 80 W/(m K)
Why is most aluminium recycled?
The metals are collected and then melted at high temperature. They then have any impurities scraped off the top of the container of molten metal. The pure molten metal is then poured into casts and cooled. The blocks of metal can now be used again. It is cheaper and less environmentally damaging to recycle metals rather than extract them from their ores, in the ground.
Why aluminium does not used for micrometer frames?
Aluminium is not typically used for micrometer frames because it is not as rigid and stable as other materials like steel or cast iron. Micrometers require high precision and accuracy, which can be compromised if the frame material is not sturdy enough. Steel and cast iron are better suited for maintaining the necessary dimensional stability and accuracy for micrometer frames.
What is used to make aeroplanes aluminium or iron?
aluminum
Why is aluminium used for aeroplanes?
Because it is light and strong.
Why is aluminum alloy used in aeroplanes?
Simply aluminium doesn't rust!!
Why are aluminium alloys used for making the bodies of vehicles and aeroplanes?
for white reducing
What is the properties and is uses of copper aluminium iron and steel?
copper aluminium iron and steel is an excellent conductor of electricity and heat is one of the properties of copper aluminium iron and steel and it is used in conducting electricity.
Why is a mixture of iron and aluminium used in power cables?
Iron strengthens the aluminum
What happens when aluminium reacts with iron oxide and where is this reaction used?

What is the most common metal used by man?
iron, aluminium, magnesium.
What materials were used to build a spitfire plane?
The Spitfire is mainly aluminium.
What property is important in the shaping of aluminium used in ships and aeroplanes?
The property important in shaping aluminium used in ships and aeroplanes is its high strength-to-weight ratio. Aluminium is a lightweight material that offers good strength, making it suitable for use in transportation industries where reducing weight is critical for fuel efficiency and performance. It allows for the construction of durable structures that can withstand the dynamic forces experienced in aerospace and marine applications.
Can iron be used to build a yacht?
Yes, iron can be used to build a yacht, but it is unadvised. Since iron rusts in water and the weight of it just isn't profitable.
How much red brick was used to build Saint Basil's Cathedral in Russia?
zero they used aluminium
