Aleación

Alloys are composed of at least one metallic element and exhibit distinct properties compared to their constituent elements. For instance, pure iron is soft and prone to oxidation, but when alloyed with carbon, it becomes hard and corrosion-resistant.

What is a necessary component of an alloy?

• Equal parts of all elements

• At least one metallic element

• Only non-metallic elements

• No metallic elements

How do the properties of alloys compare to their individual elements?

• They are identical to the properties of the elements

• They are completely different from the properties of the elements

• They are a mixture of the properties of the elements

• They are weaker than the properties of the elements

What happens to pure iron when it is exposed to the environment?

• It becomes more flexible

• It oxidizes easily

• It remains unchanged

• It becomes harder

What is the result of combining iron with carbon?

• It becomes softer

• It becomes more prone to rust

• It becomes hard and resistant to corrosion

• It loses its metallic properties

Which of the following is a characteristic of the iron-carbon alloy?

• It is transparent

• It is resistant to corrosion

• It is highly corrosive

• It is very soft
