While an alloy to alloy tube joint won't suffer from a galvanic corrosion issue aluminium does still corrode. Just in a different manner than steel. But left out it will develop an aluminium oxide that packs the joint and locks things together over time. It is definetly still wise to ensure that the metal is greased or use that carbon gel stuff to act as an oxygen and moisture inhibitor.
