Overview
Along with 380, this alloy is also known as "architectural bronze". That is a bit of a misnomer though, as this is brass, not bronze. It polishes up to a great finish, resists corrosion in non-marine environments well, and it also machines comparably well to 360. Additionally, it is rated excellent for hot working, but poor for cold forming. 385 is easy to braze and solder, but it should not be welded. It is typically used in architectural applications and ornamental hardware.
