Maxtop Copper wire drawing oil (MTCWDO) is a type of metal wire drawing oil, also known as copper wire drawing liquid, copper drawing oil, or copper drawing oil. It is an additive used in the drawing process of copper and its alloys. It is formulated with low-viscosity lubricating oil as the base oil and the addition of various additives. Containing fatty anti-friction agents and synthetic extreme pressure additives, it significantly reduces the coefficient of friction and decreases the production of copper powder. Improve the surface smoothness of the wire, prevent fraying and scratches, and increase the yield of finished products.
