Copper Nickel 90/10 Fasteners are primarily made up of 90% Copper (Cu) and 10% Nickel (Ni), with small amounts of Iron (Fe) and Manganese (Mn) added to boost their strength and durability. They boast a tensile strength ranging from 275 to 350 MPa, a yield strength of 105 to 150 MPa, and exceptional ductility along with corrosion resistance. These fasteners are perfect for extended use in environments rich in chlorides, such as marine and chemical settings. Their impressive resistance to stress corrosion cracking, pitting, and biofouling, combined with good thermal and electrical conductivity, makes them a trustworthy choice for both structural and functional fastening needs.
