Pure copper (C101) does not offer high machinability but delivers high conductivity due to its 99.99 percent material purity. Pure copper is highly expensive as well. Instead, you can use C110 since it is easier to machine and is cheaply available. We suggest you define your project functions as it helps choose the right material grade.

Machinability ratings are "relative" ratings. They compare the ease of machining an alloy to a standard. That standard is 160 Brinel hardness B1112 cold drawn steel machined at 180 surface feet per minute. B1112 was assigned a score of 1.00. The machinability of all other alloys is compared to the standard score of 1.00.
