CNC & Sheet Metal Materials Guide

Welcome to our comprehensive material resource center. Whether you need high-precision CNC machining or custom sheet metal fabrication, selecting the right material is critical for part performance, cost, and lead time. Below you’ll find detailed information on the materials we commonly work with, along with their key properties and typical applications.

CNC Machining Materials

CNC machining (milling, turning, EDM) supports a wide range of metals and engineering plastics. Our capabilities include 3‑axis, 4‑axis, and full 5‑axis machining with tolerances down to ±0.005mm.

Sheet Metal Fabrication Materials

Our sheet metal capabilities include laser cutting, bending, punching, and welding. We work with a variety of materials in thicknesses from 0.5mm to 6mm.

• Aluminum 5052 – excellent formability and corrosion resistance, ideal for marine and chemical applications.
• Stainless Steel 304/201 – durable, easy to clean, used in kitchen equipment, enclosures, and automotive trim.
• Cold Rolled Steel – tight tolerances, smooth surface, suitable for precision sheet metal parts.
• Galvanized Steel Sheet – zinc-coated for superior corrosion resistance, widely used in outdoor enclosures and construction.
