Question

Which sentence is about industry trends for exotic metals and superalloys is true?

A. Given their high cost to create and machine, the aerospace and power generation industries are moving away from the use of exotic metals.
B. Within the next five years, parts that use exotic metals and superalloys will be created exclusively through non-traditional machining.
C. Water jet cutting and electrical discharge machining (EDM) are examples of non-traditional methods used to machine some superalloys.

Answer 1

The correct answer is option C. Water jet cutting and electrical discharge machining are examples of non-traditional methods used to machine some superalloys.

Step-by-step explanation:

The correct sentence about industry trends for exotic metals and superalloys is option C: Water jet cutting and electrical discharge machining (EDM) are examples of non-traditional methods used to machine some superalloys.

Water jet cutting is a process that uses a high-pressure stream of water to cut through materials, including superalloys. Electrical discharge machining (EDM) uses electrical sparks to erode and shape the material, making it suitable for machining superalloys as well.

This sentence accurately describes the use of non-traditional methods in machining some superalloys, which reflects industry trends in the use of exotic metals and superalloys.
