GD&T 101: An Introduction to Geometric Dimensioning and Tolerancing
How to Accelerate Your Engineering Builds (and Ensure You Get Parts That Fit)
CNC Machining Materials
101 and 110 copper alloys offer excellent thermal and electrical conductivity, which make them natural choices for bus bars, wire connectors, and other electrical applications. While 101 (also known as super-conductive copper) offers higher conductivity due to its purity (99.99% copper), 110 is generally easier to machine and thus more cost-effective.

McMaster Part Number
Copper has a shiny reddish-orange finish, which varies slightly based on the surface finish method. Copper can be media-blasted and polished to achieve many different cosmetic surface finishes.

Cost Saving Tip
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
