Which of the following metals is best suited for embedments in concrete or masonry?

When metals are embedded in concrete or masonry, corrosion resistance is a critical factor due to

the alkaline environment and potential moisture exposure.

Stainless steel has excellent corrosion resistance, making it ideal for embedments in concrete or

masonry where long-term durability is required.

Bronze is corrosion-resistant but typically used for decorative or hardware applications, not structural

embedments.

Aluminum corrodes readily in alkaline concrete environments and is not suitable for embedments

without protective coatings.

Cast iron is susceptible to rust and corrosion in moist conditions and is generally avoided for

embedded components.

Thus, stainless steel is best suited for durability and corrosion resistance in concrete/masonry

embedments.
