There are many zinc alloy nickel plated key chains are worn directly in contact with the skin, some will not directly contact the skin, whether contact or not, zinc alloy nickel plated Keychain will cause harm to human health?

This question should be divided into two parts. First of all, because of its good fluidity and corrosion resistance, zinc alloy is generally used as the main material of products. The main added elements of zinc alloy are aluminum, copper and magnesium. Zinc alloy is not harmful to human body, and the surface is generally coated. Zinc alloy key chain can not be harmful to human body.

The key is the nickel coating on the outside. Nickel can stimulate the growth of blood and promote the regeneration of red blood cells, which are all based on scientific evidence. However, nickel is not completely harmless. It is only said that the harm to human body is lower than that of other properties. Because of its beautiful appearance and less harm, it is the most popular coating on the market at present. Of course, It can not be ruled out that some allergic people have a natural aversion to nickel products, which varies from person to person, and there is no absolute thing. When the human body is short of copper, the physiological activity of nickel will be fully exerted without affecting the physiological activity of copper in human body. The production of red blood cells, white blood cells and hemoglobin can be increased by adding appropriate amount of nickel. The nickel in the blood of patients with anemia and liver cirrhosis is decreased, and nickel can stimulate the blood production function.

For example, nickel plated keychain, nickel plated Keychain products generally do not directly contact the skin, the key chain is generally hung on the waist, or placed in the bag, on human health can be said to be completely harmless, after all, will not contact the skin, even if the allergic person use is no problem
