Aung Metals, located in Naypyidaw, Myanmar, stands out as a top manufacturer and supplier of high-quality **Copper Nickel 70/30 Forgings**. Renowned for their precision and durability, Aung Metals adheres strictly to international standards, producing forgings that offer exceptional corrosion resistance alongside impressive mechanical strength. The 70/30 copper-nickel alloy, which consists of 70% copper and 30% nickel, is especially prized for its remarkable ability to resist seawater corrosion, biofouling, and erosion, making it a perfect fit for marine and offshore applications. Thanks to advanced forging techniques and a commitment to rigorous quality control, Aung Metals’ Copper Nickel 70/30 Forgings promise reliable, long-lasting performance across various critical industries.
These forgings, made up of 70% copper and 30% nickel, often include small amounts of iron and manganese to boost their strength and corrosion resistance. This alloy is known for its excellent toughness, ductility, and resistance to stress corrosion cracking, all while maintaining good thermal and electrical conductivity. In terms of mechanics, the forgings boast a tensile strength of around 400–600 MPa and high yield strength, making them well-suited for high-pressure, high-stress, and challenging environmental conditions.
