Pros: Extremely lightweight and portable with excellent corrosion resistance (will never rust). Its excellent thermal conductivity dissipates heat very quickly. It’s a non-ferrous, non-magnetic option that’s great for welding stainless or aluminum parts without contamination. Least likely material to scratch the parts you’re working on.
Cons: It’s a much softer material, making it prone to scratches and dents from heavy use. It’s non-magnetic, which can be a disadvantage for some fixturing. It’s also more expensive than carbon steel and provides less stability due to its low weight.
