THey help fulfill demand in ATEX directive 94/9/EC for work in zones 1, 2, 21 and 22. This means that they are safe to use in an atmosphere where a mixture of air and flammable substances in the form of gas, vapor air mist or dust is likely to occur in normal operation occasionally. They have a hardness of 23-35 HRC, making them not quite as durable as CuBe tools. They also have low magnetism due to minimal ferrous components, making them appropriate for non-critical non-magnetic applications.
