Our Monel K500 bar is a total game-changer for high-strength aerospace fastener components, built to tackle the toughest conditions in aircraft and spacecraft systems. This nickel-copper alloy, with about 65% nickel, 30% copper, and a boost from aluminum and titanium, is our go-to for applications where strength, corrosion resistance, and reliability are non-negotiable. Whether it’s bolts, structural supports, or other fastener components for commercial jets, military planes, or even spacecraft, this bar keeps things locked in tight.

What makes Monel K500 bar stand out is its incredible mechanical strength and hardness, thanks to the aluminum and titanium additions. It’s perfect for fasteners that need to withstand intense vibrations, high stress, and fatigue during flight operations. Plus, it’s corrosion-resistant, shrugging off saltwater, humidity, and acidic environments, which is a big deal for aircraft operating in coastal regions or harsh weather conditions.
This bar’s versatility is a major win. It’s stable up to 650°C, which is ideal for fastener components near hot engine zones or high-performance systems. Its moderate electrical conductivity (~3-4% IACS) is handy for applications with electrical integration, and its high fatigue resistance ensures it keeps performing under constant stress. From passenger planes to space exploration vehicles, Monel K500 delivers unmatched reliability.
We love how workable this bar is, even with its extra toughness. You can machine, cut, or forge it into whatever your fastener design needs—think precision bolts or custom supports. Need a specific diameter, length, or finish? We can tailor it to fit your specs, keeping your production smooth and your components top-notch.

Our Monel K500 bar sets the standard because we’re all about quality, customization, and customer success. We offer a wide range of diameters, lengths, and finishes, with fast delivery for both small and large orders. Our team dives into your project, optimizing the bar for your aerospace fastener components to ensure maximum strength and corrosion resistance. We keep pricing competitive, especially for bulk orders, without cutting corners on quality. Our sustainable production process uses recyclable materials, aligning with green aerospace trends. Plus, our hands-on support means you’re always covered—whether it’s technical guidance or a custom solution, we make it happen.
Compared to other materials, our Monel K500 bar is a standout. Monel 400 is great for corrosion resistance but lacks K500’s strength for high-stress fastener applications. Stainless steel 17-7 PH is tough but struggles with chloride corrosion, unlike K500. Titanium alloys are lightweight but pricier and less fatigue-resistant in some cases. Our bar is the ultimate choice for high-strength aerospace fastener components.
We craft our Monel K500 bar to meet strict standards like ISO 9001, ensuring quality you can trust every time. Whether you’re building bolts for commercial jets or supports for spacecraft, this bar’s ready to perform. Got a unique spec in mind? Let us know, and we’ll make it happen.
