Abstract (en)

An alloy for heating rollers consisting essentially of, by weight, 0.4 to 0.6% of Fe, 0.15 to 0.6% of Cu, 0.6 to 1.5% of Mn, and 3.0 to 4.5% of Mg; and the Si content being restricted to less than 0.5% by weight; and aluminum and inevitable impurities for the remaining part. Preparing an alloy of this concentration, it is possible to provide an aluminum alloy which is excellent in strength, machinability, and formability, and where blackening process for improving the heat absorption efficiency can be completed by oxidizing the surface thereof at a high temperature.
