Copper alloys perform well at cryogenic temperatures - mechanical properties actually improve as the temperature falls.

---

However, copper significantly loses strength and ductility at higher operating temperatures. Alloy 10X is a copper-cobalt-beryllium-zirconium alloy explicitly developed to solve this problem.

Bucking the trend:

The material bucks this trend and retains performance properties at temperatures up to 800° F (430° C). Alloy 10X is a copper-cobalt-beryllium-zirconium alloy explicitly developed to solve this problem. While retaining desirable ductility and strength levels, the product also benefits from outstanding resistance to thermal cracking and high thermal & electrical conductivity. It represents an ideal material solution for continuous operation in engineering applications requiring high strength at temperatures above 575° F (300° C).

Product Suitability:

The material performance characteristics make the alloy highly suitable for high-performance applications. For example, the motorsport sector utilises Alloy 10X in applications such as powertrains and exhaust valve seats.

Processing:

Processing alloys containing beryllium is potentially hazardous because inhaling beryllium particles in the air may cause respiratory system damage and, in the worst-case scenario, lung disease. Thankfully, we safely process beryllium copper alloys in-house to precise tolerances, from cut billets to sawn plates and tubes. Thanks to our unique barcoding system, our products are also fully traceable while under our care.

Availability:

We offer Alloy 10x directly from stock in solid round bars. Forgings are also available on request. Related material specifications include ASTM B441 (C17500), RWMA Class 3.
