Processing and process characteristics
Superplastic forming supports the processing of 0.2mm ultra-thin wall parts
Good weldability, suitable for complex component manufacturing

Antioxidant and protective properties
Easy to coat aluminum oxide or HfC SiC gradient coating, oxidation rate ≤ 0.5mg/cm ² · h at 1400 ℃

Application adaptability
Space rocket nozzle, satellite propulsion system (print density 99.94%)
Nuclear reactor fuel cladding (low neutron absorption cross-section)

Production process
Using vacuum melting and plasma rotating electrode atomization (PREP) technology to ensure material purity, cold rolling forming controls wall thickness to ± 0.05mm, and achieves complex structure additive manufacturing through laser powder bed fusion (L-PBF), with a finished product density of 99.94%. Surface coating with aluminum oxide or HfC SiC gradient coating significantly improves the oxidation resistance at 1400 ℃.

Application Fields
1, Aerospace propulsion system
Rocket engine nozzle

• As a high-temperature gas flow channel (operating temperature>2000 ℃), its creep resistance can withstand repeated thermal shocks.
• Additive manufacturing (L-PBF) achieves complex internal cooling channels, improving specific impulse efficiency by 15%.

Satellite attitude control

• Used for attitude control engine thrust chamber, lightweight design reduces satellite launch costs (saving approximately $5000 for every 1kg weight reduction).

2, Nuclear energy field
Nuclear fuel cladding tube

• Replacing traditional zirconium alloys (such as N36), the neutron absorption cross section is reduced by 40%, extending the fuel cycle period.
• The hydrogen embrittlement resistance at 1400 ℃ is superior to that of zirconium alloy, making it suitable for high-temperature gas cooled reactors.

Heat exchanger pipeline

• As a sodium/liquid lead bismuth alloy isolation barrier in sodium cooled fast reactors, it is resistant to liquid metal corrosion at a rate of less than 0.01mm/year.

3, Industrial equipment
High temperature hydraulic system

• Used for high-pressure pipelines of spacecraft actuators (working pressure 35MPa), with a fatigue life of up to 10 cycles.

Chemical reactor components

• In hydrofluoric acid production equipment, the corrosion resistance is three times higher than that of Hastelloy alloy, and the maintenance cycle is extended to more than 5 years.

With the increasing demand for ultra-high temperature materials in spacecraft, C103 alloy is breaking through its application limits through composition optimization (such as adjusting the hafnium titanium ratio) and new coating technologies. The maturity of its additive manufacturing process will promote the mass production of personalized customized components, which may be compatible with reusable rockets and deep space exploration equipment in the future.
