Copper (Cu): Wuhan Iron and Steel Daye ore by the steel refining, often contain copper. Copper can improve the strength and toughness, especially atmospheric corrosion. The disadvantage is that during thermal processing prone to thermal embrittlement, significantly reduces the copper content exceeds 0.5% plasticity. When the copper content is less than 0.50% no effect on weldability.
