What is an alloy?

Back

An alloy is a mixture of two or more metals, or a metal and another element, designed to enhance certain properties.

Front

Why are metals alloyed?

Back

To change the properties of the metal.

Front

What is steel?

Back

Steel is an alloy made primarily of iron and carbon, often combined with other elements to improve its properties.

Front

Why is steel alloyed with other metals?

Back

To make it stronger, lighter, and more resistant to corrosion.

Front

What property allows metals to conduct electricity?

Back

Metals have free-moving electrons that allow them to conduct electricity.

Front

What does it mean for a metal to be malleable?

Back

Malleability is the ability of a metal to be shaped or deformed without breaking, often by hammering.

Front

What is ductility in metals?

Back

Ductility is the ability of a metal to be stretched into a wire without breaking.

Front

What is brittleness in materials?

Back

Brittleness is the tendency of a material to break or shatter without significant deformation.

Front

How do alloyed metals become stronger?

Back

They have atoms of different metals in them, which makes it harder for the layers to move past each other, making them less likely to break.

Front

What is luster in metals?

Back

Luster is the shiny appearance of a metal's surface, which reflects light.
