Cupronickels are a group of copper-nickel alloys known for their superior resistance to corrosion, especially in seawater and challenging environments. These alloys combine the best properties of copper and nickel in varying compositions. Two of the most commonly used cupronickel alloys are 70/30 and 90/10. At Columbia Metals, we stock both, and here’s what you […]

In the world of precision engineering, the need for reliable, high-integrity materials is paramount. For applications where safety and performance are critical, understanding the characteristics of metal alloys is essential. This includes testing their chemical composition, mechanical properties, and – crucially – the absence of internal defects. Why Detecting Internal Defects Matters Internal flaws such […]

Copper alloys have long been valued for their corrosion resistance and excellent friction characteristics, particularly in marine applications and bearing components. However, they often lack the mechanical strength required for high-stress environments. Over time, alloy development has bridged this gap, leading to the introduction of advanced copper alloys capable of delivering high strength alongside copper’s […]

In earlier posts, we explored how alloying elements and microstructure affect the mechanical strength and corrosion resistance of various alloys. In this post, we’ll focus on a key process that enhances these properties: precipitation hardening. Also known as age hardening, this is a thermal treatment used to increase the strength and yield strength of certain […]

We’re going to take a deep dive into a detailed comparison of two heavyweights in the world of nickel alloys: Monel Alloy 400 and Hastelloy C276. Both are widely used in the chemical processing industry where they are prized for their mechanical performance and corrosion resistance. They are, however, quite different alloys and contain different […]

When selecting materials for industrial applications, it’s crucial to understand the specific characteristics and suitability of different alloys. Alloy 400 and Alloy 625 are two nickel-based alloys that often come up in discussions due to their unique properties and widespread use across various industries. Here, we compare these two alloys to help you make an […]

Within the Monel family of nickel-copper alloys there are two particular alloys, Alloy 400 and Alloy K500, that appear outwardly to be very similar. An in-depth examination reveals there are differences between the two. Further explanation of these differences can prove of benefit in issues of material selection. In this post we will look at […]
