ABSTRACT:
Metal filter for a particulate trap which meets the requirements for low pressure drop, high collecting capacity and a long life. The metal filters have one or more layers of unwoven fabric (such as felt) formed of a metal fiber having one of the following alloy compositions A, B and C wherein composition A is made of Ni: 5-20% by weight, Cr: 10-40 by weight, Al: 1-15% by weight, the remainder being Fe and inevitable impurities; composition B is made of Cr: 10-40% by weight, Al: 1-15% by weight, the remainder being Ni and inevitable impurities; and composition C is made of Cr: 10-40% by weight, Al: 1-15% by weight, the remainder being Fe and inevitable components. The metal filter is highly resistant to corrosion and heat and can withstand repeated heatings for removal of the particulate.
