MATERIALS & CERTIFICATIONS

Metallic materials for WAAM

Industrial alloys for manufacturing, repairing, and optimizing components

Sindri Industries' WAAM technology, developed with the technological support of MX3D, is based on industrial welding principles and allows working with a wide range of metal wires.

From carbon steels, stainless steels and duplex steels to Inconel, aluminum, bronze and copper: we select the alloy according to the operating conditions of each component.
