03. Applications
- High-Load Bearings & Bushings: Ideal for sliding bearings and bushings in heavy machinery operating under extreme pressure.
- Precision Gears & Worm Wheels: Designed for gear systems that require high wear resistance and dimensional stability.
- Engine & Valve Components: Perfect for valve guides and engine parts subject to high temperatures and mechanical stress.
- Automotive Transmission Parts: Widely used for synchronizer rings, shift forks, and wear pads in transmission systems.
- Hydraulic & Pneumatic Systems: Reliable for high-pressure pump components and control valves requiring precision sealing.
- Complex Machined Parts: The best choice for intricate parts needing both high strength and excellent machinability (CNC precision).
- Marine Hardware: Durable fittings and components that demand a balance of strength and corrosion resistance.
