Description of Zirconium Fasteners & Zirconium Screws
Zirconium fasteners and screws are manufactured from zirconium and exhibit defined corrosion resistance and mechanical properties. They have a high melting point and maintain stability under harsh conditions. They deliver reliable performance in corrosive atmospheres, at elevated temperatures and in chemically aggressive media such as acids and alkalis. Given their non‐magnetic properties and biocompatibility, they are suitable for use in aerospace, medical devices and marine environments. Zirconium bolts are precision engineered to withstand rigorous conditions, thereby ensuring long‐term durability and the integrity of critical structures such as chemical processing facilities, nuclear reactors and ships.
Application of Zirconium Fasteners & Zirconium Screws
1. Chemical processing: Equipment and machinery that are exposed to corrosive chemicals, for example pumps, valves and reactors in chemical plants. This product is suitable for fastening components in corrosive environments where resistance to acids, alkalis and saline solutions is essential.
2. Aerospace and aviation: Owing to their low weight, high strength and corrosion resistance, they are used in aircraft engines, airframes and structural components. They are employed in critical aerospace applications, for instance for fastening components in spacecraft and satellites.
3. Marine and offshore: Used in ships, offshore platforms and underwater structures where corrosion resistance to sea water and saline conditions is required. They are applied for fastening equipment and structures that are exposed to rigorous marine conditions, including shipbuilding, offshore drilling rigs and underwater pipelines.
4. Medical devices: Utilised in surgical implants and medical instruments because of zirconium’s biocompatibility, non-toxicity and resistance to body fluids. They are suitable for orthopaedic implants, dental implants and cardiovascular devices, where corrosion resistance and biocompatibility are crucial to ensuring long-term functionality.
5. Nuclear industry: Due to zirconium’s low neutron absorption and its resistance to corrosion in high-temperature and high-radiation environments, it is used in nuclear reactors, fuel processing plants and facilities that handle radioactive materials. It is applied for fastening reactor components, fuel rods and structural elements in nuclear installations.
6. High-temperature applications: Employed in high-temperature environments such as furnaces, boilers and power generation plants where conventional fasteners may become compromised. This product is suitable for securing components in heat exchangers, gas turbines and other equipment subject to elevated temperatures.
Multiple sizes are available, and custom products are manufactured to specification.
