Metals
-
Aluminum Alloys – 6061, 7075, 5052; lightweight, corrosion-resistant.
-
Stainless Steel – 304, 316; excellent corrosion resistance.
-
Carbon Steel – Strong and cost-effective.
-
Titanium Alloys – Aerospace-grade strength and corrosion resistance.
-
Copper & Brass – Conductive and easy to machine.
-
Magnesium – Ultra-lightweight, good strength-to-weight ratio.
Plastics
-
POM (Delrin) – Low friction, high stiffness.
-
PEEK – High temperature resistance, biocompatible.
-
PTFE (Teflon) – Excellent chemical resistance.
-
Nylon, ABS, Polycarbonate, Acrylic – Common engineering plastics.
Tip: Material selection affects machining speed, tool wear, cost, and finish quality. For example, titanium requires slower feed rates, while plastics need low heat buildup to prevent deformation.
