Product Description:
| Product Name | Copper Alloy 173 Beryllium Rods/Bars |
| Grade | Alloy 173 |
| End Product Form | Rods/ Bars |
| Standard | ASTM B196 |
| State of product | TD04 |
| Processing | Seamless / Welding |

CUBERYLLIUM® maintains an inventory of beryllium copper alloys, including beryllium copper strips, beryllium copper rods/bars, beryllium copper wires and so on.
The normal grades of beryllium copper alloy are C17200 and C17300, with high strength and moderate conductivity. C17200 & C17300 can be purchased in the solution annealed or cold worked tempers and can be easily formed or machined. A low-temperature heat treatment (600 degrees for 2-3 hours ) produces additional maximum strenght and hardness.
Chemical Composition of Copper Alloy 173 beryllium:
| CUBERYLLIUM® Brand | UNS-Number | Beryllium | Cobalt + Nickel | +Cobalt + Nickel + Iron | Pb | Copper |
| Cuberyllium-C173 | C17300 | 1.80-2.00 | 0.20 min | 0.6 max | 0.2～0.6 | Balance |
Note: Copper plus additions equal 99.5% minimum.
