Rustproof: A-grade TC4 titanium alloy material, corrosion-resistant, no rust.
Level 10.9: Equivalent to 10.9 grade steel screws. (Only for TC4 material titanium alloy products)
Vacuum nitriding & Anodizing: Using "Vacuum nitriding" or "anodizing" coloring process, the color is gorgeous and not easy to change color

Pure titanium: low strength and low price. It is suitable for equipment that does not require strength and only meets anti-corrosion requirements Recovery/secondary smelting titanium: inferior quality, low price. There is no security.

Using the vacuum nitriding coloring process, the color penetrates into the metal surface, and the color is bright and durable. It will not fade easily with non-strong scratches.
