The meaning of alloy

• a metal that is made by mixing together two or more metals, or a metal and another substance, the major component is a metal

• Alloy is made to overcome some of the shortness in pure metals

•  Alloying is done for many reasons, typically to increase strength, increase corrosion resistance, or reduce costs.

  
  

• The resulting mixture forms a substance with properties that often differ from those of the pure metals, such as increased strength or hardness.

Multiple Choice

Which of these is an alloy?

• carbon dioxide

• iron

• steel

• pure gold

Multiple Choice

Alloy is a ...

• A chemical compound with combination between metal and non-metal

• A salt contain of two or more elements where the main element is non-metal

• Mixture of two or more elements where the main element is metal

Multiple Choice

‘Bronze is harder than copper’. Which of the following is the best to explain the statement?

• Atoms in bronze are arranged closely packed and less empty spaces.

• Layers of atoms in bronze are not easily slide over each other.

• Atomic size of copper and tin is different.

• Bronze is a mixture of copper and tin

Multiple Choice

Which of the following properties does not belong to an alloy as compared to its pure metal?

• Stronger

• More corrosion resistant

• Harder

• More malleable

Multiple Choice

Which of the following is not the aim of alloying?

• To increase the strength and hardness of metal.

• To prevent corrosion of metal.

• To improve the appearance of metal

• To increase the melting point.

Multiple Select

Why we apply bronze over copper for making statues

• Bronze is harder than copper

• Bronze is more ductile and malleable than copper

• None of the above
