Experience Unmatched Performance with CuNi Alloy Wire CuNi14 NC020 The Perfect Choice for Your Applications
CuNi14 is a copper-nickel alloy containing approximately 14% nickel, known for its excellent corrosion resistance, mechanical strength, and thermal stability. This alloy is specifically designed for demanding environments, particularly in marine and industrial applications where durability, reliability, and resistance to harsh conditions are critical.
CuNi14 consists of 86% copper and 14% nickel, with trace elements often added to enhance specific properties such as wear resistance and mechanical stability. The higher nickel content significantly boosts its resistance to corrosion, especially in seawater, and provides improved strength and hardness compared to lower nickel-content copper alloys.
