In immersion tests conducted in 48% hydrobromic acid (HBr) and 36% hydrochloric acid (HCl) at 60°C for 72 hours, SPRON510 exhibited a low weight loss rate. Compared with a Ni-based heat-resistant alloy, an ASTM B574 nickel alloy, a corrosion-resistant Co-Cr alloy, and SUS316L, SPRON510 showed lower weight loss due to corrosion under the same test conditions and demonstrated excellent corrosion resistance in strong acid environments.

The Co-Ni alloy composition of SPRON510 forms a passive protective film on the material surface, helping to suppress corrosion. As a result, SPRON510 provides excellent corrosion resistance in aggressive acidic environments, including hydrobromic acid and hydrochloric acid.

SPRON510 combines four key advantages—high strength, excellent resilience, superior corrosion resistance, and non-magnetic properties—delivering a level of performance unattainable with conventional metal materials.

SPRON510 is our proprietary Co-Ni alloy primarily composed of cobalt (Co) and nickel (Ni), with chromium (Cr) and molybdenum (Mo) additions. It offers an ultimate tensile strength of up to 2,940 MPa, a transverse rupture strength of up to 5,684 MPa, a hardness of up to Hv 800, a high Young's modulus of 216–225 GPa, and non-magnetic properties.

 SPRON510 is used in a wide range of high-reliability applications, including medical devices, precision machinery, semiconductor manufacturing equipment, and fluid control systems. Its combination of high strength, excellent spring-back characteristics, corrosion resistance, and non-magnetic properties makes it particularly suitable for components operating in harsh and corrosive environments. By helping improve durability, stability, and service life, SPRON510 contributes to the long-term reliability and quality of critical products and equipment.
