Our valve seat is manufactured from high-strength 7075-T6 aluminum alloy utilizing precision CNC machining.

To optimize performance in harsh automotive environments, the component undergoes hard anodizing treatment. This post-processing phase enhances surface hardness, corrosion resistance, and thermal stability, ensuring no discoloration at 130℃ working temperature and effectively extending total operational service life.

We are ready to bring this high level of precision and thermal reliability to your next automotive project. We warmly welcome you to partner with Vios—let’s discuss how we can optimize your component performance today.
