What is Titanikel Plating?

Titanikel plating is a sophisticated technology developed by Hyway, involving a blend of titanium and nickel applied through a high-temperature steam plating process at 900 to 1000 degrees Celsius. This creates a robust, wear-resistant surface perfect for engine components.

Titanikel Plating Process:

The process starts with multi-composite electroplating, coating the cylinder with a titanium-nickel composite. After plating, the surface is polished with diamond tools to achieve an exceptionally smooth finish due to titanium's high strength.

Benefits of Titanikel Plating:

• High Temperature Resistance: Can handle extreme temperatures, ensuring the cylinder remains intact under heavy use
• Durability: The titanium-nickel combination enhances wear resistance, significantly extending cylinder life
• Chemical Resistance: Titanium's natural resistance protects against environmental factors
• Smooth Operation: Ultra-smooth finish reduces friction, improving efficiency and reducing wear on other components
• Optimal Strength-to-Weight Ratio: Balances high strength and low weight, crucial for cut-off saw performance

Compatibility:

Stihl Models:

• Stihl TS410
• Stihl TS420

Note: Professional installation is recommended to ensure proper fit and performance. Verify compatibility with your specific Stihl model before purchasing.
