Latest Patents

Dunbar's latest patents focus on the creation of aluminum coated ferritic base metal foils. These foils are formed by the cold reduction of hot dip aluminum coated ferritic steel strips, which contain between 10% to about 35% chromium, up to 3% aluminum, and up to 1% silicon. The innovative design features a ratio of aluminum coating thickness on both sides to base metal foil thickness of at least 1:10, with a minimum of 4% by weight total aluminum. The production method involves heating the foil in an oxidizing atmosphere under specific temperature and time constraints, resulting in a porous surface with a thin layer of aluminum oxide. This foil is particularly suited for fabrication into monolithic support structures for catalytic converters used in internal combustion engine exhaust systems.
