70% to passThe heat exchanger plates, used in the device shown in the illustration, are produced from which of the listed materials? Illustration MO-0110
ATitanium
BCopper
CAnodized aluminum
DPhosphor bronze
AI Explanation
The correct answer is A) Titanium. Titanium is commonly used for the heat exchanger plates in marine applications due to its corrosion resistance, high strength-to-weight ratio, and ability to withstand the harsh marine environment. The Coast Guard regulations and industry standards often specify the use of titanium or other corrosion-resistant alloys for this type of equipment to ensure durability and safety. The other options, such as copper, anodized aluminum, and phosphor bronze, would not be the optimal material choice for this application as they are more susceptible to corrosion, have lower strength-to-weight ratios, or may not meet the specific requirements for marine heat exchangers.
