Materials We Can/Cannot Cut

 Abrasive Waterjets are a unique cutting method because they can cut almost any material known to man. The materials customers most typically recruit our help for are:

Aluminum, Brass, Bronze, Copper, Dies, Fiberglass, Granite, Graphite, Inconel, Invar, Kirksite, Limestone, Magnesium, Marble, Plastics, Rubber, Steel, Stainless Steel, and Titanium.

We are not however limited to these specific stock types as we are constantly updating our library of exotic materials. When Copeland is presented with a material that we aren’t accustomed to, we typically perform a machinability test to verify its properties and compare those properties to steel. This comparison gives us a factor which we can then, in turn, use during the cutting process to figure out the “feed rate”, slow down around corners and allow our pierces to penetrate/dwell in one spot long enough to start the cutting.

Among the very few materials that waterjets cannot cut are diamonds and tempered glass. Diamonds are too hard to cut. Tempered glass will shatter when it is cut with a waterjet (tempered glass is designed to shatter when it’s disturbed and is frequently used in windshields for this very reason). A few advanced ceramics are so hard that it’s not economical to cut them. Some composite materials (layers of different materials sandwiched together) can’t be cut because the water can seep between the layers and “delaminate” the material. However, there are some techniques we have acquired over the years that allow us to attempt to cut some laminated materials. Many composite materials cut just fine.
