From insulated roofing to heat sink in your PC to HVAC systems, copper is found in dozens of applications. High quality laser cut copper improves any project, whether it’s functional or purely aesthetic.
Copper, only surpassed by silver in its electrical properties, is perfect for hospital settings due to its antimicrobial nature. In diagnostic equipment, you’ll find this material assisting in transmitting signals for examination and providing the necessary structure in small, vital implants.
Send us your design and we’ll help you manufacture the highest-quality busbars, heat sinks, connectors and more.
