Choosing the Right Material for Robotics Parts

Material selection drives weight, stiffness, wear resistance, thermal behavior, and cost. Robotics and automation components often combine multiple materials in one assembly — a lightweight aluminum arm link, a hardened steel shaft, a bronze bushing, and a POM gripper finger may all sit inside the same mechanism.

The guides below cover the materials RobotPartsCNC machines most often, including their typical grades, machining characteristics, finishing options, and the robotics applications where each performs best. If your drawing specifies a material we have not listed, send it over — we regularly source and machine specialty alloys and engineering plastics.

Metals

Aluminum, stainless steel, carbon and alloy steel, titanium, brass, copper, and bronze.

Engineering Plastics

POM, PEEK, nylon, PTFE, UHMW, ABS, and polycarbonate for insulation, low friction, and weight reduction.

Finishing & Treatment

Anodizing, hard anodizing, passivation, black oxide, plating, bead blasting, and laser marking.

Documentation

Material certificates, inspection reports, CMM data, and lot traceability on request.

Material Capability at a Glance

Every material guide is backed by the same machining, inspection, and finishing infrastructure. Tolerance and finish depend on material, geometry, and part size.

01

Machining Range

3-axis, 4-axis, and 5-axis milling, precision turning, and mill-turn machining for complex multi-setup parts.

02

Size Envelope

Milling up to 1000 × 600 × 600 mm and turning up to Ø400 × 800 mm, covering most robot joint and housing geometries.

03

Quality Control

CMM, optical measurement, bore and pin gauges, thread gauges, and surface roughness testers with documented reports.
