How to Choose the Correct Alloy for Your Application
 Aluminum-Bronze (AlBr) AlloyCopper-Beryllium (CuBe2) Alloy
Zone CompatibilityFulfill demand in ATEX Directive 94/9/EC for work in Zones 1, 2, 21 and 22Fulfill demand in ATEX Directive 94/9/EC for work in Zones 0, 1, 2, 20, 21 and 22
Hardness27 HRC38 HRC
DurabilityNot as durable as CuBe.Very durable due to high hardness and tensile strength.
Magnetic PropertiesLow magnetism due to minimal ferrous components. Appropriate for non-critical non-magnetic applications.Non-ferrous components; safer for applications demanding non-magnetic properties.
