Semih Metals stands out by offering dependable products through advanced manufacturing processes, competitive pricing, and prompt delivery, making it a go-to partner for clients in search of high-performance materials tailored for both critical and cutting-edge uses.
Nitinol Superelastic Bars are primarily made up of nickel and titanium, typically in a ratio of about 55% nickel to 45% titanium. This distinctive composition is what gives the alloy its famous superelastic and shape-memory characteristics. Mechanically, these bars showcase impressive flexibility, fatigue resistance, and durability even under cyclic loading conditions. They can endure significant deformation and revert to their original shape without any permanent distortion. Plus, they boast high corrosion resistance, making them ideal for tough environments. The blend of elasticity, toughness, and biocompatibility makes Nitinol Superelastic Bars essential for industries that prioritize precision and performance.
