Brian Fasteners, a leading Houston, USA-based manufacturer and supplier, provides a specialized series of Copper Nickel Screws. These precision-fastened Copper Nickel Screws are meant for use in applications that need superior corrosion resistance and consistent joining in rough conditions. Our Copper Nickel Screws provide lasting performance and secure connections in marine, industrial, and specialty equipment where standard materials may fail.
Copper Nickel Screws are usually made from Copper Nickel 70/30 (C71500) or 90/10 (C70600) alloys. These alloys consist mainly of copper and 10-30% nickel, with trace amounts of iron and manganese. This composition has superior seawater corrosion, biofouling, and stress corrosion cracking resistance. They have fair mechanical properties, such as moderate tensile strength (e.g., 303-414 MPa for 90/10) and reasonable ductility, for applications in joining.

Copper Nickel Screws have extensive application in marine life where boats are manufactured, docks are constructed, and equipment is installed underwater due to their excellent resistance to seawater and biofouling. They are also crucial in chemical plants, desalination units, and air conditioning systems where corrosive media are used. Their durability and long life render them suitable for electronics enclosures, switchgear, and similar equipment where robust non-corroding fasteners are needed.
Copper Nickel screws at Brian Fasteners are packed carefully so that their quality is not compromised in any way. Every screw is packed in a protective material to avoid any form of damage, rusting, or contamination during transportation. Our packaging material is a durable carton and we provide packaging services to suit your particular needs.
