Copper Laser Cutting Services

MJM Manufacturing, Inc. provides precision copper laser cutting services from its 44,000 sq ft facility in Miami, Florida. Copper is one of the most reflective metals — making it notoriously difficult for CO2 laser systems. MJM’s five Amada fiber laser cutting systems, including the Amada Ventis, handle copper’s high reflectivity without back-reflection risk, delivering fast, clean, precise cuts on C110 electrolytic tough pitch, C101 oxygen-free, C122 phosphorus deoxidized, and other copper alloys. MJM serves electrical, electronics, defense, OEM, and power distribution customers. Quotes in 24–48 hours. Email sales@mjmmfg.com or call (305) 620-2020.

Why Fiber Laser for Copper Cutting

Reflectivity
Solved

Fiber Laser Handles Copper’s High Reflectivity

Copper reflects up to 95% of CO2 laser energy — making CO2 cutting of copper unreliable and potentially damaging to the laser optics. Fiber lasers operate at a wavelength that copper absorbs much more effectively, making fiber laser the only practical choice for precision copper cutting. MJM’s Amada fiber laser fleet cuts copper cleanly across all gauges without back-reflection risk.

Clean
Precise Cuts

Clean, Precise Edges for Electrical Applications

Copper laser cutting applications typically involve electrical busbars, contacts, heat sinks, and connectors where edge quality and dimensional accuracy directly affect electrical performance. MJM uses nitrogen assist on copper cuts to produce clean, oxide-minimized edges ready for forming, plating, or direct use in electrical assemblies.

Copper Laser Cutting — FAQ

Who does copper laser cutting in Miami, Florida?

MJM Manufacturing, Inc. provides precision copper laser cutting from its Miami, Florida facility at 5205 NW 161 Street. MJM’s Amada fiber laser fleet cuts C110, C101, C122, and other copper alloys for electrical, electronics, defense, and OEM customers. Call (305) 620-2020 or email sales@mjmmfg.com.

Can CO2 lasers cut copper?

CO2 lasers struggle with copper due to its extremely high reflectivity — reflecting up to 95% of CO2 laser energy back into the optics, risking equipment damage and producing unreliable cuts. Fiber lasers are the correct technology for copper cutting. MJM’s five Amada fiber laser systems cut copper reliably and precisely across all gauges.

What copper grades does MJM laser cut?

MJM cuts C110 (electrolytic tough pitch — most common electrical copper), C101 (oxygen-free high conductivity — OFHC), C122 (phosphorus deoxidized), and other copper alloys. Email sales@mjmmfg.com with your specific alloy, temper, gauge, and quantity for a detailed quote within 24–48 hours.
