METAL FLASHING MATERIALS Building Advisor

Lead is a very stable, non-reactive metal, so this is a bit of a mystery. Lead, or the run-off from lead, can cause corrosion in aluminum under some conditions, but aluminum should not harm lead. Where the lead has turned white, this is a natural patina of lead carbonate caused by the reaction of lead with carbon dioxide in the air.

Zinc processing | Britannica

The zinc blast furnace should actually be referred to as the zinc-lead blast furnace, since, beginning with the first successful recycling of lead drosses from the condenser, blast-furnace operations evolved to the handling of mixed zinc-lead feed materials up to a ratio of 2:1 zinc to lead.

Extracting Lead Materials from Ore

Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.

Compatibilities

When zinc contacts copper in the presence of an electrolyte (such as water) a galvanic reaction will lead to corrosion of the zinc and subsequent failure of the roof or wall cladding. Run-off from a copper surface to a zinc surface must be avoided under all circumstances. Zinc in contact with mild (carbon) steel is not desirable, either, due to
