Our Monel 400 wire is a total game-changer for seawater-cooled heat exchanger tubes, built to stand up to the harshest marine environments without missing a beat. This nickel-copper alloy, with about 67% nickel, 30% copper, and a touch of iron and manganese, is our go-to for applications where corrosion resistance and reliable heat transfer are must-haves.

What makes Monel 400 wire so special is its unbeatable ability to resist seawater corrosion. Whether it’s high-flow saltwater or stagnant coastal waters, this wire doesn’t flinch, making it perfect for heat exchanger tubes, fittings, and wire mesh in marine and desalination systems. It fights off pitting and stress corrosion cracking, ensuring your heat exchangers keep running smoothly with minimal maintenance.

This wire’s versatility is a big win. It’s stable up to 550°C, which is plenty for seawater-cooled heat exchangers in ships, offshore platforms, or desalination plants. Its moderate electrical conductivity (~3-4% IACS) is handy for systems with electrical integration, and its high ductility means it can handle mechanical stress without breaking. From coastal power plants to marine vessels, Monel 400 delivers top-notch performance.

We love how easy this wire is to work with. Its excellent formability lets you shape, weld, or draw it into whatever your heat exchanger design needs—fine wires for mesh or thicker ones for tubing. Need a custom diameter or tensile strength? We can tailor it to fit your specs, making manufacturing quick and keeping your project on track.

The industry’s all about materials that are corrosion-resistant, efficient, and sustainable, and Monel 400 wire checks every box. It’s recyclable, which is great for eco-friendly projects, and its long lifespan means less waste from replacements. With desalination and marine energy systems growing—driven by global water shortages and offshore wind—demand for materials like Monel 400 is soaring. Its low maintenance also supports the trend toward cost-effective, green marine solutions.

Our Monel 400 wire sets the bar high because we’re all about quality, customization, and customer success. We offer a wide range of diameters and tensile strengths, with fast delivery for both small and large orders. Our team dives into your project, optimizing the wire for your heat exchanger tubes to ensure maximum corrosion resistance and heat transfer efficiency. We keep pricing competitive, especially for bulk orders, without skimping on quality. Our sustainable production process uses recyclable materials, aligning with green industry trends. Plus, our hands-on support means you’re never left guessing—whether it’s technical advice or a custom solution, we make it happen.

Compared to other materials, our Monel 400 wire is a clear winner. Monel K-500 is stronger but slightly less corrosion-resistant in seawater, making 400 the better pick for heat exchanger tubes. Stainless steel 316 is tough but struggles with chloride corrosion in saltwater, unlike Monel 400. Pure copper’s a conductivity champ but corrodes fast in marine environments. Our wire is the ultimate choice for seawater-cooled heat exchanger applications.

We craft our Monel 400 wire to meet strict standards like ISO 9001, ensuring quality you can trust every time. Whether you’re building heat exchangers for ships or desalination plants, this wire’s ready to perform. Got a unique spec in mind? Let us know, and we’ll make it happen.
