Acupuncture Needles
Acupuncture needles are made of metal, with stainless steel being the preferred material due to its high strength and toughness. Stainless steel needles are straight, smooth, heat-resistant, rust-resistant, and resistant to corrosion by chemicals, making them widely used in clinical practice. Other metal needles, such as gold needles and silver needles (which have better heat conductivity), are less commonly used in clinical settings.

Pure Silver Needle
Pure silver needles are made of silver, which is a soft metal, to facilitate acupuncture. They are mainly used in scientific research, such as in MRI (magnetic resonance imaging) examinations, where stainless steel needles are affected by the magnetic field environment and silver needles are used instead.

Gold-plated Needle, Silver-plated Needle
Gold-plated needles have a layer of gold plated on the outer surface of stainless steel needles. They have the toughness of stainless steel needles and the good conductivity of gold needles. However, they are less commonly used due to their high cost.
