Copper Nickel 70/30 bolts are crafted from an alloy that consists of roughly 70% copper and 30% nickel, along with trace amounts of iron and manganese to enhance mechanical strength and corrosion resistance. This alloy boasts remarkable resistance to seawater corrosion, erosion, and stress corrosion cracking. Generally, these bolts display tensile strengths ranging from 310 to 355 MPa, a yield strength close to 125 MPa, and an elongation of about 30%. They uphold their structural integrity even under high pressure and elevated temperatures, making them perfect for demanding applications in marine and industrial fields.
