Beta titanium is a metal that excels in strength and high corrosion resistance compared to stainless steel, and has excellent spring properties (low Young's modulus) that allow it to return to its original shape even after bending. Beta titanium is used in various fields such as medical and analytical applications, and is also widely utilized in consumer products. For example, in fishing rods, beta titanium is adopted due to its corrosion resistance, lightweight nature, and improved impact strength compared to conventional materials. Additionally, for eyeglass frames, which require the ability to maintain their original shape after bending, beta titanium pipes with excellent superelasticity are ideal. Furthermore, Nikku Precision Machinery Industry provides special anti-loosening screws for eyeglasses, titanium materials for eyeglasses, and processing materials through retailers! 【Features】 ■ Superelasticity that returns to its original shape even after bending ■ Excellent corrosion resistance ■ High strength ■ Lightweight *For more details, please download the catalog or contact us.

Beta titanium is a metal that excels in strength and high corrosion resistance compared to stainless steel, and it has excellent spring properties (low Young's modulus) that allow it to return to its original shape even after bending. Due to its superelasticity that allows it to return to its original shape and its durability when heat-treated, beta titanium pipes are being adopted. The durability after heat treatment is more than four times that of stainless steel, which reduces the frequency of replacement for consumable parts and leads to a reduction in total costs. Additionally, beta titanium pipes, which have superior chemical resistance and corrosion resistance compared to stainless steel, are used in analysis nozzles. Furthermore, beta titanium, which does not contain iron, is gaining attention because the iron component in stainless steel can cause erroneous analyses. 【Features】 ■ Superelasticity that withstands bending due to mechanical malfunction ■ Durability over four times that of SUS when heat-treated ■ Longer lifespan of consumable parts ■ Iron-free *For more details, please download the catalog or contact us.

Beta titanium is a metal that excels in strength and high corrosion resistance compared to stainless steel, and it has excellent spring properties (low Young's modulus) that allow it to return to its original shape even after bending. Due to its strength, corrosion resistance, and biocompatibility, it is increasingly being adopted as a medical instrument in the medical field. For example, catheters and stents that enter blood vessels, as well as surgical scissors (forceps), require superelasticity. Additionally, in MRI surgeries, materials that do not cause artifacts (false images) when images are displayed on a monitor and are non-magnetic are required, making beta titanium, which possesses both properties, a focus of attention. 【Features】 ■ High strength ■ Excellent corrosion resistance ■ Biocompatibility not found in stainless steel ■ Prevention of artifacts in MRI *For more details, please download the catalog or contact us.

The Tube Catcher for vial handling is a convenient tool for organizing and moving vials intended for low-temperature storage. Previously, the only method for moving ultra-low temperature storage containers was with tweezers. This Tube Catcher is made of titanium, which is resistant to low temperatures and has materials that do not easily conduct heat, so even if the tip becomes ultra-low temperature, the handle remains safe to hold, allowing for safe operation.
