Plasma cutting is typically used on which materials?

• A. All of the above
• B. Steel
• C. Aluminum
• D. Copper

Answer: (A)

Plasma cutting relies on an electrical arc that ionizes gas into plasma, producing an extremely hot stream that melts and blows away metal. Because the arc must travel through the workpiece, plasma cutting works on electrically conductive metals. Steel is a common target, aluminum is routinely cut due to its conductivity, and copper can be cut with the right settings as well. So, all of the above is correct because plasma cutting handles these conductive metals.
