🛠️ 1. Product Overview

Our C103 Niobium-Hafnium alloy spherical powder (Composition: Nb-10Hf-1Ti) is manufactured using advanced [Radio Frequency (RF) Plasma Spheroidization / Plasma Rotating Electrode Process (PREP)] technology. As a classic refractory superalloy, C103 maintains exceptional mechanical strength and creep resistance in extreme high-temperature environments ranging from 1200℃ to 1482℃ (2200°F - 2700°F).

This powder features ultra-high sphericity, virtually no satellite particles, ultra-low oxygen content, and outstanding flowability. It is specifically engineered for Directed Energy Deposition (DED/LMD), Electron Beam Melting (EBM), and Selective Laser Melting (SLM) 3D printing processes. It is widely applied in the additive manufacturing and surface modification of aerospace rocket engine nozzles, attitude and orbit control thruster chamber liners, missile nozzle extension sections, and corrosion/high-temperature resistant components in the nuclear industry.

🌟 3. Core Product Advantages

• Designed for Laser Cladding with Outstanding Dynamic Flowability: Rigorous sieving and spheroidization processes ensure perfectly spherical powder particles with no satellite particles or agglomeration. During Directed Energy Deposition (DED), the powder feeds smoothly and continuously, resulting in a stable melt pool transition and a highly smooth cladding surface.
• Extreme Low-Oxygen Control for Superior Material Strength in Harsh Environments: Produced in a fully physical vacuum environment with strict control over interstitial elements (O, N, H, C). The ultra-low oxygen content effectively prevents composition oxidation and micro-crack formation during cladding, significantly enhancing the metallurgical bonding strength between the cladding layer and the substrate.
• Exceptional High-Temperature & Thermal Shock Resistance: The precisely proportioned Hafnium (Hf) and Titanium (Ti) in the alloy form a protective oxide film at high temperatures. Workpieces laser-clad with this powder remain completely free of peeling and cracking, even when subjected to severe thermal cycling (rapid heating and cooling at thousands of degrees).
• Full Supply Chain Quality Traceability: From the selection of raw refractory niobium ingots to vacuum melting, spheroidization, sieving, and final argon-filled vacuum packaging, our entire process complies with international quality management systems. We provide fully traceable laser particle size analysis and ICP chemical composition reports.

🚀 4. Typical Applications

• Aerospace Surface Modification: Laser cladding repair and direct additive manufacturing for rocket engine nozzle extensions, thrust chambers, and valve liners.
• Corrosion-Resistant Components: High-temperature resistant surface coatings for gas rudders and thermal protection systems of hypersonic vehicles.
• Petrochemical & Nuclear Industries: Cladding protection for special corrosion-resistant valve seats and pipelines operating in extreme acid/alkali, intense radiation, and high-temperature molten salt environments.

📦 5. Professional Packaging, Logistics & Storage

• Custom Protective Packaging: 1kg / 2kg bags feature double-layer anti-static high-purity aluminum foil bags with vacuum sealing. The outer layer is additionally sealed in argon-filled iron or stainless steel drums, ensuring absolutely no leakage or moisture absorption during transit.
• Storage Recommendations: Store in a cool, dry, vibration-free dedicated warehouse for hazardous/refractory powders. After opening, please use the powder promptly inside an inert gas (argon/nitrogen) glove box.
• Efficient Supply Chain: We maintain ready stock of base materials and support sample testing. We provide direct delivery via domestic specialized logistics, and support compliant export customs clearance for overseas air and sea freight.
