Product Description
Description
A zirconium bolt is a fastener made from the metal zirconium, known for its exceptional corrosion resistance and ability to withstand high temperatures.
Zirconium fasteners are ideal for corrosive environments such as chemical processing, marine, and nuclear applications. They are also lightweight and maintain strength in extreme conditions.
Common zirconium grades include Zr702 (UNS R60702), Zr704 (UNS R60704), and Zr705 (UNS R60705) — each offering specific combinations of mechanical and corrosion resistance properties.

Applications
Zirconium fasteners are used in industries that demand superior corrosion resistance and mechanical stability under extreme environments:
Chemical and petrochemical plants
Nuclear reactors and power systems
Aerospace and marine engineering
Heat exchangers and condensers
Valves, pumps, and flanges
Medical and pharmaceutical equipment
Fuel and oil systems
Cryogenic systems
Zr702 bolts are ideal for chemical and marine applications.
Zr704 and Zr705 bolts are preferred in high-stress and high-temperature environments due to their enhanced strength.
Properties
-
Outstanding resistance to acids, alkalis, and seawater.
-
High melting point and excellent thermal stability.
-
Non-magnetic, non-toxic, and biocompatible.
-
Lightweight yet strong for aerospace and nuclear use.
-
Excellent wear and oxidation resistance.
-
Can be custom-machined to complex shapes and threads.
