Aerospace wear parts are precision-engineered components designed to endure extreme conditions in aircraft, including high-speed friction, impact, and corrosion. Made from wear-resistant materials like tungsten carbide and coated alloys, these parts—bushings, pins, fasteners, and sleeves—ensure reliable operation of landing gear, actuators, and engine systems. Manufacturers such as Rettek provide OEM-grade solutions that maximize lifespan and minimize maintenance costs.

What Materials Are Used in Aerospace Wear Parts?

Wear-resistant tungsten carbide is favored for aerospace components due to its exceptional hardness and toughness. Often combined with cobalt binders, it withstands impact and abrasion. Rettek utilizes advanced sintering to achieve consistent density and uniform performance across all parts. Other materials include hardened steel with nickel plating for corrosion protection and DLC coatings for low-friction applications, offering tailored solutions for landing gear, bearings, and fasteners.

What Applications Do Aerospace Wear Parts Serve?

Aerospace wear parts are critical for landing gear systems, flap actuators, wheel drive keys, and engine mounts. These components endure repeated friction, impact, and corrosion under extreme conditions, such as high-speed landings or turbine operations. Rettek's carbide inserts and pins extend service life, reduce downtime, and maintain precise movement in actuators and wheel assemblies. Bulk OEM supply from China factories ensures consistent quality and cost efficiency.

Why Choose Carbide for Aerospace Parts?

Carbide components offer 10–20 times longer life than steel equivalents, combining extreme hardness (HRA 90+) with impact resistance. Rettek’s in-house sintering ensures uniform density and compliance with aerospace standards. Carbide withstands high temperatures, resists corrosion from de-icing chemicals, and reduces maintenance costs. Lifecycle analysis shows significant savings over conventional metals, making carbide an ideal choice for critical aerospace applications.

How Are Aerospace Wear Parts Manufactured?

Manufacturing begins with powder metallurgy: batching tungsten carbide powder, pressing at 100–200 MPa, vacuum sintering at 1400–1600°C, and precision grinding to tight tolerances. Rettek controls the full production chain, including alloy preparation, HIP sintering to eliminate porosity, CNC grinding for Ra 0.2µm finishes, and automated brazing of carbide tips onto steel bases. This ensures reliable, defect-free parts for large-scale OEM supply.

What Advantages Do China Manufacturers Offer?

China-based manufacturers like Rettek provide cost-effective aerospace wear parts with full-chain production capabilities. Vertical integration—from raw tungsten to finished components—reduces logistics and markups. Rapid prototyping and scalable production support bulk orders, while strict quality management meets ISO 9001 and aerospace certifications. Rettek’s engineering expertise ensures custom geometries and specifications for global OEMs, enhancing operational efficiency.

Which Coating Enhances Durability Most?

Tungsten carbide-cobalt (WC-Co) coatings applied via HVOF spraying provide the highest durability for aerospace wear parts, with thicknesses of 0.5–1 mm and bond strength exceeding 70 MPa. Rettek applies these coatings directly in-house, ensuring long-lasting performance in high-friction and impact applications. Electroless nickel sealing and DLC options further improve corrosion resistance and reduce friction for moving components.
