Bristow Nickel Alloys, in Midland, UK, is a top producer and distributor of high-performance nickel alloys. With years of experience, the company has on offer a wide variety of high-quality alloy products for use in various industries. Among their products are copper-nickel fasteners, which are noted for their high corrosion resistance, strength, and durability in marine and offshore conditions. Bristow Nickel Alloys is dedicated to providing quality solutions that meet the stringent requirements of industries like marine, petrochemical, and energy, ensuring reliability and customer satisfaction with each product.
Copper-nickel fasteners usually contain 90% copper and 10% nickel, providing superior corrosion resistance, particularly in seawater and aggressive marine conditions. The alloy also includes trace amounts of iron and manganese to add strength and endurance. From the mechanical perspective, copper-nickel fasteners have high tensile strength, usually between 300 and 600 MPa, and elongation properties, all contributing to stress and wear resistance. Physically, such fasteners have a density of approximately 8.9 g/cm³ and a melting point of about 1,250°C, rendering them well suited for applications needing high strength, corrosion resistance and thermal stability.
