For professional sporting events, Zinc Alloy is the preferred material due to its high plasticity and durability. You should specify Die-Casting processes for 3D designs that capture the intricate scales of the dragon. For premium finishes, request Electroplating in gold, silver, or bronze with an Anti-Oxidation coating to prevent tarnishing. If the budget is limited, Iron or Brass with soft enamel can be used, but ensure they are treated for corrosion resistance given the humid environment of water sports.
