The construction of boiler tubes typically involves materials that can withstand high temperatures and pressures, as well as provide resistance to corrosion and stress. Carbon steel and alloy steel are commonly used due to their excellent mechanical properties, high strength, and ability to conduct heat effectively.

Carbon steel is often used for its affordability and adequate strength at elevated temperatures, making it suitable for many types of boilers. Alloy steel enhances these properties further by including elements like chromium, molybdenum, or nickel, which improve resistance to oxidation and make the material more durable in harsh operating conditions.

Other materials listed, such as copper and aluminum, are generally not suitable for high-pressure boiler applications due to their lower melting points and weaker mechanical properties at elevated temperatures. Options like plastic and fiberglass are not viable for boiler tubes because they cannot withstand the high heat and pressures encountered in boiler environments. Lastly, while cast iron may be used in some specific boiler designs, it is generally not favored for tube construction due to its brittleness compared to steel. Stainless steel, though resistant to corrosion, is less commonly used for boiler tubes in large-scale applications, mainly due to cost considerations.

Thus, carbon steel and alloy steel are the most practical and commonly used materials for constructing boiler tubes, making this choice
