• 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 products)
• Vacuum nitriding & Anodizing: Using "Vacuum nitriding" or "anodizing" coloring process, the color is gorgeous and not easy to change color

Titanium Alloy: high quality class A titanium alloy, corrosion resistance and high strengt Processing is difficult and expensive. It's mostly used in aerospace,or for F1, motorcycle GP and other international events.
Pure Titanium: low strength, low price. It is applicable to the equipment that does not require strength but only meets the requirements of corrosion protection. Recycled / Remelted Titanium: inferior, low price. No security.
