This is a substantial buckle, made of nickel-free zinc alloy. It is cast metal, and is not "tinny" like less expensive, stamped out buckles. It is good and solid and it will not bend. It has the appearance of the more expensive chrome finish buckles, but made of lighter weight zinc alloy. Photos clearly show the details.
