Copper Machining Company - AT Precision

Copper is a ductile metal. It is an excellent conductor of electricity and heat, and is very corrosion resistant. Popular copper alloys are C101 (OFHC or OFE), C145 (Free Machining Tellurium) and C172 (Beryllium) copper. All of these alloys still contain a minimum of 99.3% pure copper. Copper is also alloyed with zinc to produce brass and with ...

machining copper - Practical Machinist

The copper or silver is easy to cut, but wants to stick to the cutting tool. On a milling cutter, the chip sticks to the edge and then pressure welds to the copper when it comes around. You need rake and clearance on your cutting tool, the rake to make the chip slide off without attaching and clearance to avoid scuffing.
