Copper 18150 Hex Bar 1" hex Retail Price

About 18150|Chromium copper (99% copper, 1% chromium). Precipitation-hardenable to moderate strength (60–70 KSI tensile) while retaining about 80% of pure copper’s electrical conductivity. The go-to alloy for resistance welding electrodes and applications requiring the combination of strength, conductivity, and heat resistance. Machines better than pure copper in the hardened condition since the chromium gives chips more body. No beryllium toxicity concerns. Compare to 17510 beryllium copper (much stronger but toxic dust) and C110 (softer, higher conductivity, no heat resistance).

About Hex Bar|Six-sided bar stock used for bolts, nuts, fittings, and any part that needs a wrench-friendly grip. It self-centers in a 3-jaw chuck, making it common in screw machine and CNC lathe work.
