C11400 alloy copper strip contains silver, which gives it high strength and enables it to excel in environments where it is required to withstand high levels of stress or load. Despite the addition of silver, C11400 copper foil maintains good electrical conductivity, making it popular for applications where electrical conductivity is required. The addition of silver helps to increase the toughness of the alloy, making it more durable and reliable in a variety of engineering applications.
