What metals can a torch cut?

A torch, specifically an oxy-acetylene torch, is commonly used in construction and metalworking for cutting through metals. Among the options provided, wrought iron and steel are the most suitable candidates because they have properties that respond well to the intense heat produced by an oxy-acetylene flame.

When using a torch, the heat needs to reach the metal's melting point, which is effective for wrought iron and steel due to their relatively high melting points. The flame can easily oxidize the iron and steel, allowing for clean cutting. Wrought iron has a composition that makes it suitable for this cutting method, while steel can vary in its constituents but typically will cut effectively with this method as well.

The other metals listed—aluminum, copper, brass, bronze, lead, and zinc—have different melting points and characteristics that may make them less ideal for cutting with an oxy-acetylene torch. For instance, aluminum can melt quickly and may not cut as cleanly, while copper could reflect heat and present difficulties in cutting. The same applies to brass and bronze; they may require different techniques or tools entirely. Meanwhile, lead and zinc have lower melting points and unique properties that make cutting them with a torch not ideal since they can produce harmful fumes
