What to look for when choosing a laser cutting nozzle?
There are two general parameters you should look out for when choosing a nozzle - the Layer and the Caliber. Here’s a general rule on how to select the Calibre based on material thickness
Material Thickness (mm)
|Nozzle Diameter (mm)|
|3-10 || ~2|
Nozzles usually come in single or double layers. The type of layer you choose depends on what gas you will primarily use in the cutting process - typically Air, Oxygen, or Nitrogen.
Additionally, the gas you select will also depend on the type of material you cut. Here’s a table on how to select the best nozzle Layer depending on your gas and material.
| Auxiliary Gas||Material|
|Single || Air or Nitrogen || Galvanised Steel, Stainless Steel|
|Double || Oxygen || Carbon Steel, Aluminium|
