Hakan Nickel Alloys, based in Istanbul, Turkey, stands out as a top manufacturer and supplier of high-quality Copper Nickel 70/30 fasteners. This company is dedicated to providing robust, corrosion-resistant fastening solutions tailored for challenging marine, offshore, and industrial environments. With a reputation for precision engineering and strict adherence to international standards, Hakan Nickel Alloys boasts an extensive selection of fasteners, including bolts, nuts, washers, and screws. Their focus on durability, performance, and customer satisfaction ensures they meet the needs of global markets with prompt delivery and expert technical support.
Copper Nickel 70/30 fasteners are crafted from an alloy that consists of about 70% copper and 30% nickel, along with small amounts of iron and manganese to boost strength and corrosion resistance. This unique alloy excels in resisting seawater corrosion, erosion, and stress corrosion cracking. Typically, these fasteners exhibit mechanical properties such as a tensile strength ranging from 310 to 355 MPa, a yield strength of around 125 MPa, and an elongation of about 30%. They maintain their reliability and structural integrity even under high pressure and elevated temperatures, making them perfect for tough environments.
