Veer Impex is a devoted firm that manufactures and supplies Cupro Nickel 70/30 fasteners. When it comes to high-quality products, we always stand behind all steel grades, including Cupro Nickel 70/30 nuts and bolts, which have a wide range of features in various environments.
Cu Ni 70/30 alloys are the copper-nickel grades that also contain other strengthening elemental compositions such as iron and manganese. Copper and nickel content of 70% and 30%, respectively, and iron and manganese content of up to 2% and 2%. Cu Ni 70/30 alloy is more resistant to corrosive conditions and erosion than Cu Ni 90/10 alloy due to these elemental balances. Cu Ni 70/30 fasteners are applicable at high temperature and pressure environments, whereas the high velocity and destructive turbulence conditions are not that good.
Cu Ni 70/30 is primarily intended for use in marine conditions, where it prevents the production of thin, adhering protective layers made up of cuprous oxide and hydrochloric acids, as well as iron and nickel oxide, which can cause corrosion. Cu Ni alloys are resistant to chlorides, and sulfides stress corrosion cracking and any hydrogen embrittlement. They do not crack due to ammonia in seawater, while the presence of ammonia may speed up corrosion rates.
