Technical regulation and scope of ASTM B196
The ASTM B196 standard defines strict technical requirements for the production and quality of beryllium copper rod and bar. This specification covers alloys with high mechanical strength and excellent electrical conductivity, which are indispensable in the aerospace, instrumentation, and oil and gas industries. Specialists at EV Group China ensure the supply of rolled products that fully comply with these standards.
Below are the alloy grades covered by the standard, with their nominal chemical composition:
| Copper Alloy UNS | Historical trade name | Nominal Beryllium content, % |
| C17000 | Alloy 165 | 1.7 |
| C17200 | Alloy 25 | 1.9 |
| C17300 | – | 1.9 + 0.4 lead |
The use of C17000, C17200, and C17300 alloys allows engineers to design components with increased wear resistance and stable performance under cyclic loads. Experts at EV Group China are ready to provide consultation on selecting the optimal grade for your project.
