Manufactured from low-carbon steel (0.15% carbon content) that undergoes copper infiltration and sintering to achieve 7.2 g/cm³ density. This process delivers 350 HB hardness and thermal conductivity of 45 W/m·K for efficient heat dissipation. The copper-infiltrated matrix prevents valve micro-welding and maintains seat temperatures below 220°C even with 60°C inlet air.
- Surface finish: 0.25 µm Ra for optimal bedding
- Break-in period: 50 hours
