No, soft copper and hard copper are not the same.
Soft copper is annealed or heated to make it more malleable and easier to bend, while hard copper maintains its structure.
The main difference between the two is:
• Soft Copper - Has a higher ductility which makes it easier to bend into shapes.
• Hard Copper - Has a lower ductility which makes it less prone to bending when used in applications requiring strength. It also holds up better against corrosion over time than its softer counterpart.
