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.

Linear Motion Shafts

Smooth, hard, and wear resistant, linear motion shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. All are turned, ground, and polished to tight diameter and straightness tolerances.

Stainless steel shafts are more corrosion resistant than steel shafts; however, they’re not as hard as steel shafts and can be more difficult to machine. 17-4 PH stainless steel shafts have excellent corrosion resistance and high yield strength to support heavy loads.

Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.

Hardened shafts are heat treated for increased wear resistance.
