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.

- 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.

Extra High-Strength 172 Beryllium Copper Rods
- Yield Strength: See Table
- Hardness: See Table
- Temper:
3/8" and 5/8" dia. rods: TD04 (Hard)
All other sizes: TH04 (Hard) - Heat Treatable: Yes
- Specifications Met: ASTM B196, RWMA Class 4
Rated RWMA Class 4, 172 beryllium copper is the strongest beryllium copper alloy that is also electrically conductive and extremely wear resistant. It’s often used in inserts, die facings, and molds for plastic that need to withstand stress over repeated use. While stronger than RWMA Class 3 coppers, it has lower conductivity. 172 beryllium copper is nonsparking, so it’s safe for use in hazardous areas such as mines and oil rigs. It’s also nonmagnetic, meaning it can be used in navigational tools and computing equipment. Unlike pure copper, this alloy won’t rust when exposed to the outdoors, including marine environments.

Super-Conductive Extra High-Strength 17510 Beryllium Copper Bars
- Yield Strength: 90,000psi
- Hardness: Rockwell B98 (Medium)
- Temper: TH04
- Heat Treatable: Yes
- Specifications Met: RWMA Class 3
In addition to being conductive, these 17510 beryllium copper bars are non-sparking and non-magnetic, so they’re used in mines and oil rigs, as well as for navigational tools. The beryllium and nickel in this alloy make it stronger and more rigid than pure copper, but not as conductive. These bars are conductive enough for electrical relays, probe pins, and test-socket and modular-jack contacts, while being strong enough for welding dies, plunger tips, and injection-mold nozzles. Even after collisions and frequent use, they maintain their shape, so they’re used for molds and cavities. Meeting RWMA Class 3, they’re recommended when seam and spot welding electrically-resistant material, such as stainless steel. They also withstand extreme temperatures and won’t rust outdoors.

Easy-To-Machine 173 Beryllium Copper Rods
- Yield Strength: 50,000 psi
- Hardness: Rockwell B80 (Medium)
- Temper: TD04 (Hard)
- Heat Treatable: Yes
- Specifications Met: ASTM B196
With the addition of lead, this beryllium copper alloy forms small chips that won’t clog machines when it’s drilled or cut, so it is ideal for automated production lines. Adding beryllium to a copper base makes a normally soft copper strong and rigid. This alloy is also nonsparking and nonmagnetic. It is often used in hazardous areas such as mines and oil rigs, as well as in navigational tools, computers, and high-wear molds. Even with these other elements mixed in, this alloy still allows electric currents to pass, just like copper, but without deforming thanks to that added strength. It resists corrosion in marine environments, however it may form a green patina when exposed to oxygen and oxides.

EMI/RFI Shielding Gaskets
These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems. They compress to fill gaps and complete a grounding path around doors and access panels.
Beryllium copper gaskets withstand repeated compression and decompression over time, so they’re often used with doors that regularly open and close. They’re also known as fingerstock gaskets. Adhesive-back gaskets stick to flat surfaces. Install clip-on gaskets onto surfaces such as circuit board edges or enclosure door frames.
