Nickel Release Testing

Nickel is a silvery - white malleable metal with a slightly yellowish tint. It is a ferromagnetic transition metal. It is not only a basic material for manufacturing nickel alloys but also an alloying element in other alloys (such as iron - based, copper - based, and aluminum - based alloys). The application of nickel is determined by its corrosion - resistance. Adding nickel to alloys can enhance their corrosion - resistance. The stainless - steel and alloy production fields are the largest application areas of nickel.

Nickel is also an element that can easily cause contact allergies. After being released from some nickel - containing materials and having long - term contact with the skin, nickel can be absorbed by the skin, causing allergies in some individuals. Further exposure to soluble nickel salts can lead to contact dermatitis. The nickel release amount is a concern for certain items that have direct and long - term contact with the human body, such as metal rivets, buttons, fasteners, zippers, metal plates, and labels on clothing, jewelry, mobile phones, and other products.
