Copper

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.

Material Properties

110 Copper

Tensile Strength：42,000 psi (1/2 hard)

Elongation at Break：20%

Hardness：Rockwell F40

Density：0.322 lbs / cu. in.

Maximum Temp：500° F

101 Copper

Tensile Strength：37,000 psi (1/2 hard)

Elongation at Break：14%

Hardness：Rockwell F60

Density；0.323 lbs / cu. in.

Maximum Temp:500° F

Material Finish

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.

Design Recommendations

Min Wall Thickness：0.5 mm

Min End Mill Size：0.8 mm (0.03 in)

Min Drill Size：0.5 mm (0.02 in)

Max Part Size：1200 x 500 x 152 mm[(x,y,z] (mill) 152 x 394 mm [d,h] (lathe)

Undercuts：Square profile, full radius, dovetail profiles

Radii（Depth） ：

· Depth must not exceed 12x drill bit diameter.

· For end mills, depth must not exceed 10x drill bit diameter.

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.
