Copper to Aluminum Electrical Connectors Advanced Custom Design and Manufacturing

Our copper to aluminum connectors are made properly to ensure long joint life and problem free service.  We know that thermal expansion, galvanic corrosion, joint creep and contact surface quality all need to be considered when properly designing a copper to aluminum connector.

We offer several successful approaches in fabricating copper to aluminum joints including:

• Explosion bonded copper to aluminum weldments
• Bimetallic washers
• Silver sponge
• Nickel, Tin and Silver plating
• Joint compounds with properly designed bolting hardware
