High-Strength 182 Copper Bars

Yield Strength: 40,000 psi
Hardness: Rockwell B65 (Medium)
Temper: H04 (Full Hard)
Heat Treatable: Yes

182 copper is stronger, harder, and more wear resistant than 110 copper. Also known as RWMA Class 2 chromium copper, it's commonly used in resistance welding, for circuit-breaker parts, and for molds to make plastic parts.

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.

Marine-Grade Copper Nickel Sheets

Yield Strength: 15,000 psi
Hardness: Not Rated
Temper: M20
Heat Treatable: No
Specifications Met: ASTM B171

Make plates for offshore drilling platforms, water boxes, valves, and other marine equipment that withstands salt water. Also known as cupro nickel, these copper nickel sheets resist rusting better than stainless steel. They also resist damage from algae and barnacle buildup, so you can even use them to build boat hulls—no protective paint needed. When carrying heavy loads, they won’t crack from chlorides, though they’re more likely to develop small holes from sulfides compared to stainless steel. They’re also sometimes used to house copper tubes to stop them from corroding nearby metal.

Like other copper alloys, these sheets are easy to machine and join with similar materials. You can spot weld, braze, and solder them. They carry electric currents and cool down quickly, making them good heat exchangers for fluids in HVAC systems and water treatment plants. Extreme freezing temperatures, even cryogenic levels, won’t reduce their strength or formability. They also stand up to humidity.

When cleaned regularly, these sheets prevent the growth of bacteria, viruses, and fungi. This makes them a good choice for hardware that’s touched frequently.

Magnetic Clamps

60 lbs. Max Magnetic Pull

75 lbs Max Magnetic Pull

Hold magnetic workpieces in place with these clamps.

Copper-plated clamps won’t scratch steel surfaces. The plating prevents weld spatter from sticking to the clamp, so sharp spatter won’t cut the user or their workpiece.
