1.name:burnt blue hex flange titanium bolt
2.material:titanium GR5
3.color:burnt blue
4.application:motorcycle/car
the burnt blue is with the PVD technique(Physical Vapor Deposition),it is Under vacuum conditions, the use of low-voltage, high-current arc discharge technology, the use of gas discharge to vaporize the target material and ionize the vaporized substance and gas, and the acceleration of the electric field, so that the vaporized substance and its reaction products are deposited on On the workpiece.so the color is not easy to rush
