Possibly the grade of brass. Brass is known to to dezincify and the resultant mess looks like corrosion.

Thanks for some stuff on the subject. But I am specifically looking for the possible reason of corrosion when SS tube and a Copper tube have a Brass coupling to join them. What could have triggered the Galvanic Corrosion.

-----Original question-------
My question relates to the Compatibility of distinct materials when used in assembly. To be specific, there is a case where a SS tube is joined to a Copper tube wit a brass coupling. At the joint, corrosion has set in. Why and what is the cause? What metal properties of these materials are conflicting causing corrosion.? What is actually a Galvanic corrosion?Thanks. I hope to get good and informative response.
