The manufacturing materials of acupuncture needles are mainly metals, including stainless steel, silver, copper, gold and so on. These metals have the advantages of high strength, corrosion resistance, and no allergy, which can ensure the safety and durability of acupuncture needles. Among them, stainless steel is a commonly used manufacturing material because it has good mechanical properties and corrosion resistance, and the price is relatively moderate. Other metals such as silver, copper, and gold are also commonly used to make good acupuncture needles.
In addition to metal materials, there are some non-metallic materials such as ceramics, glass, etc., are also used to make acupuncture needles. These materials have unique physical and chemical properties, such as high corrosion resistance and good biocompatibility, but the price is relatively high.
In short, the manufacturing materials of acupuncture needles are mainly metals, including stainless steel, silver, copper, gold and so on. These metal materials have good mechanical properties and corrosion resistance, which can ensure the safety and durability of acupuncture needles.
