Question

Of the following metals which cannot be efficient cut using OFC

Answer 1

Non-ferrous metals such as aluminum and stainless steel cannot be efficiently cut using Oxygen Fuel Cutting (OFC) due to their tendency to form a protective oxide layer.

Step-by-step explanation:

The student is asking about a material cutting technique known as Oxygen Fuel Cutting (OFC), which is typically used for metals. However, not all metals are suitable for this method. When it comes to OFC, non-ferrous metals, like aluminum and stainless steel, are not efficiently cut using this technique. OFC relies on the metal's ability to oxidize rapidly in the presence of high temperature and an oxygen jet. The oxidation process generates additional heat, which helps to maintain the cutting process. However, aluminum and stainless steel form a protective oxide layer that prevents efficient cutting.

Answer 2

The metal that cannot be efficiently cut using OFC is Aluminum (Al).

Step-by-step explanation:

The metal that cannot be efficiently cut using OFC (oxygen-free copper) is Aluminum (Al).

Oxygen-free copper (OFC) is a high-conductivity copper that has been processed to remove oxygen and other impurities. It is primarily used in applications that require high electrical conductivity.

While OFC is an effective cutting tool for many metals, it is not efficient for cutting aluminum. Aluminum has a low melting point and is highly reactive with oxygen, which can cause the cutting process to be less efficient and produce undesirable results.
