Water jet cutting is a computerized cold cutting technology that can cut most materials into any two dimensional shape.  Water jet cleanly and efficiently cuts all metals including stainless steel, aluminum, copper, inconel along with other exotics and tool steels.  

The water jet cutting is a clear, cold process that does not heat, harden or distort the materials that it cuts.  This is an advantage especially with stainless steel and aluminum with a "no heat effected zone."
