Wai Nickel Alloys stands out as a premier manufacturer and supplier located in Naypyidaw, Myanmar, with a focus on delivering high-quality Copper Nickel 70/30 Pipes for a variety of industrial uses. These pipes are well-known for their remarkable corrosion resistance, mechanical strength, and durability, especially in marine and chemical settings. Crafted with cutting-edge manufacturing techniques and top-notch materials, Wai Nickel Alloys guarantees precision, reliability, and adherence to international quality standards. The Copper Nickel 70/30 Pipes are celebrated for their long-lasting performance, making them perfect for applications in shipbuilding, desalination plants, offshore installations, and power generation systems.
These pipes are made up of about 70% copper and 30% nickel, along with small amounts of iron and manganese that boost their strength and resistance to corrosion and erosion. This alloy showcases impressive mechanical properties, including high tensile strength, good ductility, and exceptional resistance to stress corrosion cracking, oxidation, and biofouling. They maintain stability and performance even in high-temperature and saline conditions, making them ideal for demanding applications in seawater systems and heat exchangers. The well-balanced composition ensures toughness, weldability, and a long service life, even under extreme operating conditions.
