Bronze Powder | Bronze Pigment Powder
Description:
Bronze Powder use copper, zinc as the main raw / materials, through smelting, spray powder, ball grinding and polishing process of extremely slight flake metal powder, also called copper zinc alloy powder, commonly known as gold powder.
Characteristics:
1.Bronze Powder and forming of hue
According to different composition, the copper alloy surface can show scarlet, gold, white or even purple. The different zinc contents make the bronze powder different hue. Containing zinc is less than 10% produce pale gold effect, called pale gold; 10%-25% produce rich light golden effect, called rich pale gold; 25%-30% produce rich light golden effect, called rich gold.
2.Micro-structure and particle size distribution of bronze powder
The bronze powder particles are flaky texture, under the observation of scanning electron microscopy, the flakes most are irregular, and its edges are zigzag shape, some a few is relatively regular circle. This particle structure makes it can arranged parallel with the painted objects.
3.Bronze powder optical properties
The bronze powder has the angle-following color dissimulation effect, it is relate to the smoothness of the metal surface. The Micro-structure, coating thickness and particle size distribution all plays a vital role to influence the glossiness of printing gold.
