MP35N alloy tubing used in coronary and peripheral stents
2024-11-05
Trusted and relied upon by Medical OEMs, Lork Group combines its unrivaled metallurgical expertise and experience to engineer high-quality stent tubes.
Biocompatibility, corrosion resistance, and high strength are key material attributes for stent tubing. MP35N is an age hardenable nickel-cobalt base alloy that has a unique combination of properties - ultra high strength, toughness, ductility and outstanding corrosion resistance.
MP35N resists corrosion in hydrogen sulphide, salt water and other chloride solutions. It also has excellent resistance to crevice and stress corrosion cracking in sea water and other hostile environments. Suitable where a high combination of strength, high modulus values and good corrosion resistance are required. Applications for this alloy also include medical devices and dental products.
