C103 Plate for Rocket Nozzles
C103 niobium hafnium alloy is a classic material developed in the 1960s for liquid rocket engine thrust chambers. Its composition is Nb-10Hf-1Ti, and through the solid solution strengthening effect of hafnium element, it significantly improves the high-temperature creep resistance while maintaining good processability. This material can maintain structural integrity above 1200 ℃ and is perfectly compatible with silicon-based coating systems. It is still one of the preferred materials for regenerative cooling nozzles and extension sections.
As a specialized material supplier deeply involved in the aerospace field, we strictly follow the aerospace material process specifications and provide stable performance C103 sheets specifically for rocket engines.
Description
Core advantage: Comparison of creep resistance performance
Note: The following data is based on 1200 ℃/100h endurance testing
| Comparison item | Ordinary niobium alloy sheet | Shaanxi Zhongheng Weichuang C103 Board |
| Creep deformation amount | >2.0% | <0.5% |
| Grain growth grade | Level 3-4 | Level 1-2 |
| Coating bonding strength | 25-35MPa | ≥50MPa |
We use multi-directional cross rolling technology to produce uniform fiber flow towards the structure of the sheet. This structure can effectively prevent grain boundary slip at high temperatures, control creep deformation at an industry-leading level, and ensure the stability of the nozzle surface and the absence of deformation in the cooling channel during long-term operation of the engine.

Guidelines for Use and Protection
1. Key points of welding process
- Priority should be given to vacuum electron beam welding, and the porosity of the weld seam should be controlled within ≤ 1.5%
- Dry at 300 ℃ for 2 hours before welding to prevent hydrogen induced cracking
2. Coating activation treatment
- Sandblasting treatment: Select 120 mesh white corundum, with surface roughness controlled at Ra3.2-6.3 μ m
- Acid washing formula: HF: HONO ∝: H ₂ O=1:3:6 (volume ratio), soak at room temperature for 40-60 seconds
3. Post service inspection
- It is recommended to perform fluorescent penetrant testing after each task
- Focus on thermal fatigue cracks in the throat area
Service guarantee system
1. Technical Collaboration
- Provide suggestions for optimizing the nozzle structure
- Shared cooling channel design parameter library
2. Quality Traceability
- Each batch of materials comes with a traceability file for the melting furnace number
- Provide a video of the full process traceability from raw materials to finished products
3. Emergency response
- Establish a special space channel and coordinate the delivery of urgently needed materials within 48 hours
- Provide 7 × 24-hour technical support during the launch mission
