A
Iron and carbon
B
Copper and tin
C
Copper and zinc
D
Aluminum and magnesium
Verified step by step guidance1
Understand that brass is a specific type of alloy, which means it is a mixture of two or more metals combined to create a material with distinct properties.
Recall that brass is primarily composed of copper and zinc, which are mixed in varying proportions to produce different types of brass with different characteristics.
Recognize that iron and carbon form steel, not brass; copper and tin form bronze, not brass; aluminum and magnesium are used in other alloys but not brass.
Identify that the correct pair of metals found in brass is copper and zinc, as this combination gives brass its typical properties such as malleability and corrosion resistance.
Summarize that when asked about the composition of brass, the answer should always be copper and zinc, distinguishing it from other common alloys.
