Scaling Needles

Non-sparking scaling needles for use in petrochemical, grain production (explosive-dust), utilities, and hazmat applications.
Non-magnetic scaling needles for use in MRI/NMR, nuclear products, electronic manufacturing, and other sensitive equipment.
Corrosion Resistant scaling needles for use in desalination plants, chemical/paper manufacturing, and shipyards.

How to Choose the Correct Alloy for Your Application
	Aluminum-Bronze (AlBr) Alloy	Copper-Beryllium (CuBe₂) Alloy
Zone Compatibility	Fulfill demand in ATEX Directive 94/9/EC for work in Zones 1, 2, 21 and 22	Fulfill demand in ATEX Directive 94/9/EC for work in Zones 0, 1, 2, 20, 21 and 22
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.
