Air Products offers a full range of pure assist gases for laser cutting of all material types.

Which gases are used?

Carbon and alloy steels - oxygen or nitrogen (high pressure)
Stainless steels, aluminium & alloys - nitrogen (high pressure)
Magnesium, titanium & other reactive materials - argon
(high pressure)

Each gas has unique properties which make it the preferred assist gas for cutting each of the material groups.

All of these gases are available in a range of convenient and cost effective gas supply options.

Generally required at pressures up to 10 barg oxygen is available at two purity levels:

Industrial grade (min. 99.5% oxygen)
Lasergas grade (min. 99.95% oxygen)

The standard industrial product is the most widely used and is suitable for all material grades and thickness'. However, the Lasergas grade delivers:

Increased cutting speeds (up to 20% faster)
Reduced kerf width and improved cut quality
