Located in the heart of Hamilton, New Zealand, Hemi Metals takes pride in providing industry with high-performance materials like Beryllium Copper C17200 bars and rods. We understand that local manufacturers need reliable, high-quality components, and our role is to be that trusted local source for this exceptional alloy. Sourcing this premium material directly from our base supports Kiwi innovation and ensures you have access to a world-class product with the convenience and responsiveness of a dedicated local supplier.
The C17200 alloy is primarily composed of copper with a small but crucial addition of beryllium, typically around 1.8% to 2.0%. This unique composition gives the material its remarkable combination of very high strength, excellent hardness, and impressive electrical conductivity. In its hardened state, it can achieve a strength comparable to many steels, while still maintaining the beneficial non-sparking and non-magnetic qualities inherent to copper-based alloys, making it truly versatile.

Beryllium Copper C17200 bars maintain excellent strength, thermal conductivity, and resistance to oxidation in high-temperature environments, making them suitable for aerospace, automotive, and industrial applications requiring durability and performance.
Yes, Beryllium Copper C17200 Bars are corrosion-resistant, offering excellent resistance to oxidation, tarnish, and most atmospheric conditions, making them suitable for marine, industrial, and electrical applications.
Yes, Beryllium Copper C17200 Rods can typically be customized in size and length to meet specific requirements, depending on the manufacturer or supplier’s capabilities and production facilities.
You’ll often find C17200 bars and rods hard at work in demanding environments where failure is not an option. They are essential for manufacturing reliable, long-lasting components like heavy-duty springs, explosive tooling for oil and gas applications, and durable bearings and bushings in the aerospace industry. Their non-sparking nature is critical for safety in potentially explosive atmospheres, while their excellent conductivity makes them ideal for electrical connectors and connectors that must also withstand significant mechanical stress and wear.
