Both the statements Assertion (A) and Reason (R) are true. Also, R is the correct reason for A.
Explanation:
- Alloys are a combination of two or more metals (solid-solid mixtures).
- Alloy mixtures generally have required properties that the fundamental elements don't have on their own.
- The properties include corrosion resistance, increased tensile strength, or greater hardness.
- They are made up of two or more metals or a combination of metal and non-metal.
- They are usually measured by the unit of mass.
Example:
- Steel = Iron + carbon.
- Adding a certain proportion of chromium or nickel to iron, with some good quantity of carbon, results in the alloy known as stainless steel.
