Hi Dan,

You really wouldn't want copper hardware - it's too soft and has poor 
tensile strength. Instead, use what the power companies use for making 
solid bus bar connections - silicon bronze hardware. This alloy combines 
excellent tensile strength, corrosion resistance (it's often used in marine 
applications instead of brass) and high electrical conductivity. You can 
find silicon bronze hardware at McMaster-Carr, marine, or electrical 
hardware suppliers. You can often find it at metal recycling places 
("junqueyards") as well, especially places that accept hardware and bus 
bars from electrical and power system tear downs.

Best regards,
