The alloy contains approximately 2% beryllium, giving it superior corrosion resistance compared to other copper alloys. This makes it an ideal choice for applications where exposure to harsh chemicals may be expected. Additionally, beryllium copper 172 is resistant to hydrogen embrittlement, which can cause failure in other materials when exposed to hydrogen at high pressures and temperatures.
Adding beryllium gives the alloy superior corrosion resistance compared to other UNS C17200, making it suitable for use in marine applications or any environment where exposure to salt water may be a concern. Additionally, the lack of iron content means that beryllium copper 172 does not suffer from galvanic corrosion when exposed to dissimilar metals such as stainless steel and aluminum which can cause premature failure in other materials when subjected to similar conditions.
Beryllium copper 172 can be heat treated using various methods, including solution heat treatment and ageing treatments. These help maximize hardness while maintaining ductility levels throughout the whole part's service life cycle, making it suitable for parts requiring tight tolerances or intricate shapes. Additionally, beryllium copper C17200 offers exceptional heat resistance up to 800°C (1472°F). This makes it ideal for soldering or welding applications, such as electronic components or automotive exhaust systems, where typical materials may fail due to excessive temperatures during operation cycles.
