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
Open-End wrenches are designed for a wide variety of work. Their box opening adds still more to their versatility and strength. The Flare Nut pattern with its hex box opening is especially useful in air conditioning and refrigeration work where tubing terminates on flare nuts. The thinner and slimmer Electronic pattern is designed for work where access and clearance are limited.	Do not use the open end of these wrenches to free a "frozen" nut or final tighten a hex nut. Use the box opening. Never use an extension on the wrench handle.
