Adarsh Nickel Alloys offers a variety of copper nickel washers in different sizes, thicknesses, and custom specifications to cater to a wide range of application needs. With a strong commitment to quality control and compliance with international standards, the company guarantees consistent quality, impressive corrosion resistance, and reliable performance even in tough conditions.
Copper nickel washers are created from copper-based alloys mixed with nickel, along with small amounts of iron and manganese to boost their strength and resistance to corrosion. This unique blend provides outstanding protection against seawater corrosion, erosion, biofouling, and stress corrosion cracking. In terms of mechanics, these washers demonstrate good tensile and compressive strength, excellent ductility, high toughness, and stable performance across a broad temperature range. They maintain their shape and sealing effectiveness even under continuous mechanical stress.
