Extra High-Strength Beryllium-Free 180 Copper Bars
- Yield Strength: 90,000 psi
- Hardness: Rockwell B90 (Medium)
- Temper: Not Rated
- Heat Treatable: Yes
- Specifications Met: RWMA Class 3
These copper bars have similar performance properties to beryllium copper, but do not require special machining techniques. They’re often used for high-stress applications such as studs, welding electrodes, mold cavities, and electrical components. Even after collisions and frequent use, they maintain their shape. They conduct electricity, but not as well as purer copper, such as 101 copper. Using them in extreme temperatures won’t change their mechanical properties, but you can process them with heat treatment if you wish to alter their properties. They’re RMWA Class 3, which is a class that’s commonly used to seam and spot weld stainless steel and other electrically-resistant materials. When used outdoors, these bars won’t rust.

Extra High-Strength Beryllium-Free 180 Copper Rods
- Yield Strength: 90,000 psi
- Hardness: Rockwell B90 (Medium)
- Temper: Not Rated
- Heat Treatable: Yes
- Specifications Met: RWMA Class 3
Even though they have similar performance properties to beryllium copper, these copper rods don't require special machining techniques. They’re used for high-stress applications such as studs, welding electrodes, mold cavities, and electrical components because they hold their shape through collisions and frequent use. They conduct electricity, but not as well as 101 copper and other purer coppers. Their mechanical properties won’t change when used in extreme temperatures, but you can heat treat them if you want to alter their properties. Meeting RMWA Class 3, they’re often used to seam and spot weld electrically-resistant materials such as stainless steel. These rods won’t rust if used outdoors.
