Question
Alloys consist of a combination of two or more metal elements in their solid state.
- True
- False
Hint:
Another word is mixture.
The correct answer is: True
The statement is True.
An alloy is a mixture of chemical elements, at least one of which is a metal. Unlike metal-based chemical compounds, alloys retain all the metallic properties in the resulting material, such as opacity, electrical conductivity, ductility, and luster, but not with pure metal properties such as they may exhibit different characteristics but an increase in strength or hardness is observed.
