Features of GT STORM Al
Beautiful appearance !
GT STORM is able to obtain excellent surface without being affected by Mg alloy defect.
Dimensional uniformity !
Dimensional change before and after GT STORM processing is uniform, also Including tapped hole.
Characteristics of oxide film !
- Thickness
- adjustable, 10 to 50 μm(excellent uniformity)
※To form a thin-film with a uniform film thickness distribution
- Corrosion resistance
- Salt spray test 96 h ~ (standard: 30 m)
Comparison with anodizing treatment
| Processing method | Thickness | Corrosion Resistance (Salt spray test) |
Conductivity | Hardness | Surface Roughness | Glossiness (60°) |
