This rigidity, while excellent for maintaining tolerances during CNC machining, comes at the cost of brittleness. The material has a relatively low elongation at break, meaning it does not stretch or deform significantly before failing. Consequently, when internal or external stresses exceed the material’s tensile strength, the failure mode is almost exclusively brittle fracture—manifesting as cracks.
