Usually. Different types for different materials but you could just broadly say “sand” or “abrasives” for the stuff in the water. Its insane what this shit does. Even when using a normal pressure washer, there are attachments that allow you to introduce abrasive media into the stream with incredible results. It’s essentially sandblasting without the nasty nasty and potentially deadly dust.
The process of waterjet cutting is essentially the same as natural water erosion, accelerated and concentrated. The cutter is connected to a high-pressure water pump and water is ejected out of the nozzle. The stream of high-speed water cuts through the material as it is blasted. Sometimes, additives such as suspended grit or other abrasives like garnet and aluminum oxide can assist in the process. The nature of the cutting stream can be very easily modified, meaning the tool can be used to cut a wide variety of materials.
Water alone can't do this. These water jet cutters use sand in the water stream to cut hard things like metals. Softer things like fabrics don't use any media. Industrial water jet cutters use pressures of around 60k PSI. The machine I used to operate was able to cut up to 9" thick steel. but cutting thicker hard materials is painfully slow. A bit advantage of water jet cutting is that there is no heat affected zone in the material. IN safety critical component heat affected zones from plasma or torched cutting needs to be machined off.
