Al Vishwas Nickel Alloys distinguishes itself as a premier manufacturer and supplier of high-grade Copper Nickel Washers based in Dubai, UAE. They serve industries that require exceptional corrosion resistance and enduring dependability. Well-known for their remarkable performance in marine, offshore, and industrial environments, these washers are produced through advanced manufacturing techniques and strict quality controls. Al Vishwas’s Copper Nickel Washers deliver impressive resistance to seawater, brine, and biofouling, which makes them ideal for essential fastening applications. With a firm emphasis on accuracy, durability, and on-time delivery, the company takes pride in supporting a range of industries with reliable, high-performance Cu-Ni fastening solutions.
Copper Nickel Washers are typically available in either Cu-Ni 90/10 or 70/30 alloy compositions, combining copper with nickel plus a small amount of iron and manganese. These extra elements enhance corrosion resistance, mechanical strength, and help prevent pitting and erosion in seawater. The washers demonstrate good tensile strength, excellent ductility, and steady mechanical performance across varying temperatures. They also withstand stress corrosion cracking and biofouling, which makes them ideal for demanding applications. Their combination of toughness, durability, and corrosion resistance ensures dependable and long-lasting fastening performance.
