What is Titanikel™ Plating?

Titanikel is Hyway’s exclusive titanium-nickel composite plating applied through a high-temperature (900–1000 °C) steam fusion process. After multi-layer electroplating, the surface is diamond-polished for an ultra-smooth, extremely hard finish that far surpasses conventional Nikasil.

Benefits:

• Superior wear & scoring resistance
• Excellent high-temperature stability
• Outstanding corrosion protection
• Lower friction = cooler running & longer life

Pop-Up Piston Advantages

• Increased compression ratio → significantly more power & torque
• Better combustion efficiency → improved fuel economy
• Stronger low-end pull for cutting dense or frozen wood
