Abstract
A clip exhibiting improved corrosion resistance and reduced weight is processed by a drawing operation which is preferably conducted without interannealing treatments and which may employ a variation of drawing speeds. The clip of the present invention is prepared from an aluminum base alloy comprising from about 0.05-6.0% silicon, about 0.10-0.8% iron, about 0.02-0.3% copper, up to 1.0% manganese and up to 7.0% magnesium. The resulting clips possess comparable tensile properties to conventional tin and zinc-coated steel clips with an economy of processing.
