Why copper component fabrication in Binh Duong?
Binh Duong is southern Vietnam’s epicenter for electrical and electronics manufacturing. Within a 30 km radius of Thu Dau Mot city, hundreds of factories produce switchboards, transformers, UPS systems, power supplies, LEDs, and telecom equipment across industrial parks like VSIP, Song Than, Dong An, and My Phuoc. All of them need copper components — from a few dozen to several thousand pieces per month.
Previously, businesses in the region had to source copper components from Ho Chi Minh City or Dong Nai, adding 1-2 days of transit time and logistics costs. With a high-power fiber laser facility right in Thu Dau Mot, Laser Tuan Thinh cuts lead time to 3-5 days with free delivery across Binh Duong Province.
This article focuses on copper C1100 and brass C2680 fabrication in the 0.5-3mm thin gauge range — the most common segment for electrical, electronic, and thermal management applications. For thicker copper (up to 10mm), see our complete copper & brass laser cutting guide.
Copper C1100 — The gold standard for conductivity
Copper C1100 (Cu >= 99.9%) is irreplaceable when the application demands the highest electrical or thermal conductivity:
| Property | Value |
|---|---|
| Electrical conductivity | 100% IACS (international standard) |
| Thermal conductivity | 385 W/m-K |
| Melting point | 1,085 C |
| Density | 8.96 g/cm3 |
| Elastic modulus | 117 GPa |
The 0.5-3mm range is the most common for electronic components — thin enough to bend and solder, yet thick enough to carry substantial current.
Copper C1100 applications in Binh Duong
Busbars for switchboards and transformers
Copper busbars are the backbone of every industrial switchboard. Laser cutting creates complex shapes — bolt holes, heat-relief slots, connection tabs — in a single pass, replacing multi-step die punching. With ±0.1mm tolerance, M6/M8 mounting holes align perfectly without secondary machining.
Common range: copper 1.0-3.0mm, busbars 100-600mm long for 400V-690V panels.
Heat spreaders for LEDs and power electronics
Copper C1100 conducts heat 1.7x better than aluminum 6061, so for the same heat dissipation area, a copper sheet can be thinner and more effective. Laser cutting produces fins, ventilation slots, and chip-mounting holes with freeform profiles that punching cannot achieve.
Common range: copper 0.5-1.5mm for high-power LED heatsinks and IGBT modules.
Ground plates and PCB shims
Power electronics PCBs require copper shims between layers to increase current-carrying capacity. Laser cutting ensures profiles match the board footprint precisely, with features as small as 5x5mm.
EV battery connectors and terminals
Vietnam’s electric vehicle industry is booming, driving demand for copper connectors in lithium battery modules. Each module requires 4-8 copper connectors at 1-2mm thickness. Laser cutting enables 3-day prototype turnaround before transitioning to die punching for volume production.
Brass C2680 — Good conductivity, easy to work, lower cost
Brass C2680 (Cu 65% + Zn 35%) is the go-to choice when balancing electrical performance, machinability, and cost:
| Property | Value |
|---|---|
| Electrical conductivity | 28% IACS |
| Thermal conductivity | 120 W/m-K |
| Melting point | 930 C |
| Density | 8.53 g/cm3 |
| Hardness (HV) | 80-150 (depending on temper) |
Compared to pure copper, brass is about 40% cheaper, easier to laser cut (zinc reduces reflectivity), and accepts Ni/Cr plating readily.
Brass C2680 applications in Binh Duong
Terminal blocks for switchboards
Brass terminal blocks are standard in low-voltage panels because they offer sufficient conductivity for control circuits (not power circuits), better oxidation resistance than pure copper, and lower cost. Laser cutting combined with CNC bending forms complex terminal block shapes from 0.8-1.5mm brass sheet.
Industrial signage and decorative panels
Brass has a natural golden color and can be polished to a mirror finish. Many factories in Binh Duong’s industrial parks need signage, machine specification plates, and decorative panels from 0.5-1.0mm brass. Laser cutting produces lettering and logos with line widths as fine as 0.3mm.
Valve components and mechanical fittings
Brass resists corrosion well in water environments, making it suitable for valve bodies, flanges, and gaskets in industrial piping systems. The 1.5-3.0mm range is laser cut for flat components before further CNC machining.
Musical instrument and craft parts
The Binh Duong - Ho Chi Minh City area hosts numerous workshops producing musical instruments and export handicrafts. Brass 0.5-1.0mm is laser cut for decorative horn fittings, bells, and premium interior accessories.
Technical challenges of cutting thin copper
Thin copper (0.5-3mm) presents different challenges than thick copper. Understanding them leads to better designs:
High reflectivity — Why laser fiber fiber matters
Copper reflects approximately 95% of energy at the 1-micrometer wavelength used by fiber lasers. Older CO2 lasers cannot cut copper at all. Standard fiber lasers can cut it but risk cutting-head damage from back-reflection.
laser fiber’s latest fiber laser systems include integrated back-reflection protection, allowing safe copper cutting without lens damage. This is why we invested in laser fiber rather than other brands — specifically to serve customers who need copper fabrication.
Nitrogen only — Never oxygen
Oxygen creates a black oxide layer (CuO) on copper surfaces that is extremely difficult to remove and degrades electrical conductivity. Every copper component at Tuan Thinh is cut with high-pressure nitrogen, producing bright, oxide-free cut edges.
For electrical components (busbars, terminals), clean edges are mandatory because oxide layers increase contact resistance.
Lead-in requirements
The laser cannot pierce directly on the contour of a copper part — the reflected beam at the starting point would damage the lens. Each part requires a lead-in line from the scrap area to the cut path.
When designing, ensure at least 1mm clearance from the part edge to the raw sheet edge to leave room for lead-in paths.
Minimum feature sizes
For thin copper in the 0.5-3mm range, the practical minimums are:
| Feature | Minimum Value |
|---|---|
| Slot width | 0.5mm (0.5-1mm stock), 0.8mm (2-3mm stock) |
| Hole diameter | = material thickness (minimum 0.5mm) |
| Part-to-part spacing | >= 2x material thickness |
| Inside corner radius | >= 0.3mm |
Copper’s high thermal conductivity means features that are too small or too closely spaced will distort from heat buildup. Contact our engineers for guidance if your design includes features below these values.

Cost comparison: copper vs aluminum vs stainless
To help you choose the right material for thermal or electrical applications:
| Material | Cutting cost at 1mm (VND/m) | Thermal (W/m-K) | Electrical (% IACS) |
|---|---|---|---|
| Copper C1100 | 8,000 - 12,000 | 385 | 100 |
| Aluminum 5052 | 3,000 - 5,000 | 138 | 35 |
| Stainless 304 | 3,000 - 4,500 | 16 | 2.4 |
Copper costs 2-3x more than aluminum to cut, but conducts heat 2.8x better. For high-power LED/IGBT heatsinks, a 0.5mm copper sheet performs equivalent to 1.5mm aluminum — saving mounting space.
