What type of metal can be cut with an oxy-acetylene cutting torch?

The use of an oxy-acetylene cutting torch is well-suited for ferrous metals due to their properties and how they respond to the high temperatures generated by the torch. Ferrous metals, primarily composed of iron, can reach melting points that are conducive to the cutting process when combined with the oxygen flow from the torch. This process allows for effective cutting as it ignites the metal, accelerating oxidation, and producing a molten material that can be easily removed.

While non-ferrous metals, aluminum, and brass can sometimes be cut using oxy-acetylene torches, they generally require different techniques or specific precautions due to their varied melting points and behaviors under heat. Non-ferrous metals can be more challenging to cut properly with oxy-acetylene equipment because they may not oxidize in the same way as ferrous metals. Hence, while the torch is versatile, ferrous metals remain the most common and efficient materials processed with oxy-acetylene cutting methods.
