aluminum but have copper stub tubes at the inlet and outlet connections. Use a
heat sink on the copper stub tubes to prevent damage to the uniseal tape and
brazed connections (and the aluminum) that attach the copper stub tubes to the
aluminum micro-channel coil. The uniseal tape is used to prevent corrosion
between the copper and aluminum.
