Amazing Cool Technology combines graphene with copper with its own technology, and is the only graphene copper material in the world that can be mass-produced, and all the characteristics exceed oxygen-free copper, called "ACOOL COPPER" that has high electrical conductivity, high thermal conductivity, corrosion resistance, oxidation resistance, high adhesion, bending resistance, improved mechanical properties, high voltage resistance, low leakage, and low temperature resistivity. ACOOL COPPER can be made into wire, plate or target; and can be used in electric vehicles, semiconductor industry.
