How to Choose the Correct Alloy for Your Application

	Aluminum-Bronze (AlBr) Alloy	Copper-Beryllium (CuBe2) Alloy
Zone Compatibility	Fulfill demand in ATEX Directive 1999/92/EC for work in Zones 0, 1, 2, 20, 21 and 22, M1 & M2	Fulfill demand in ATEX Directive 1999/92/EC for work in Zones 0, 1, 2, 20, 21 and 22, M1 & M2
Hardness	27 HRC	38 HRC
Durability	Not as durable as CuBe.	Very durable due to high hardness and tensile strength.
Magnetic Properties	Low magnetism due to minimal ferrous components. Appropriate for non-critical non-magnetic applications.	Non-ferrous components; safer for applications demanding non-magnetic properties.
Composition	Al: 10.3% Fe: 4.5% Ni: 4.5% Other: 0.5% Cu: Balance	Be: 1.9% Co + Ni: 0.4% Other: 0.5% Cu: Balance

Use Guidelines

Proper Use	Misuse
Punches are designed to mark metal and other materials softer than the point end, drive and remove pin and rivets, and align holes in different sections of material.	Never use a punch with a mushroomed struck face or with a dull, chipped or deformed point.
