Metal Materials for CNC Machining
High-strength metals for functional prototypes and production parts
Aluminum6061 · 7075 · 5052 · 2024
The most popular CNC machining material — lightweight, corrosion-resistant, and easy to machine. Excellent strength-to-weight ratio for aerospace, automotive, and consumer products.
Stainless Steel304 · 316 · 303 · 17-4PH
Superior corrosion resistance and strength for medical devices, food processing equipment, marine components, and chemical handling. 316 offers enhanced resistance to chlorides.
TitaniumGrade 2 · Grade 5 (Ti-6Al-4V)
Exceptional strength-to-weight ratio and biocompatibility. The material of choice for aerospace structural parts, medical implants, and high-performance sporting goods.
BrassC360 · C260
Outstanding machinability, natural corrosion resistance, and attractive gold-like appearance. Widely used for electrical connectors, valves, fittings, and decorative hardware.
CopperC110 · C101
Best-in-class thermal and electrical conductivity. Used for heat sinks, bus bars, electrodes, and RF shielding components requiring maximum conductivity.
Mild & Carbon Steel1018 · 1045 · 4140 · A36
Cost-effective and readily available with good machinability. Ideal for structural parts, jigs, fixtures, and components requiring case hardening or heat treatment.
Plastic Materials for CNC Machining
Engineering-grade thermoplastics for functional testing and end-use applications
ABSAcrylonitrile Butadiene Styrene
Impact-resistant, easy to machine, and cost-effective. The go-to plastic for consumer product prototypes, enclosures, and snap-fit assemblies.
Acrylic (PMMA)Polymethyl Methacrylate
Excellent optical clarity (92% light transmission) and UV stability. Perfect for light guides, lenses, display windows, and automotive lighting prototypes.
Delrin (POM)Polyoxymethylene / Acetal
Low friction, high stiffness, and excellent dimensional stability. Ideal for gears, bearings, bushings, and precision mechanical components.
Polycarbonate (PC)Lexan · Makrolon
Exceptional impact strength (250× glass) with good optical clarity. Used for protective covers, safety shields, transparent housings, and lighting components.
Nylon (PA)PA6 · PA66 · PA6+GF30
High wear resistance and mechanical strength with self-lubricating properties. Used for gears, cable ties, structural brackets, and wear-resistant components.
PEEKPolyetheretherketone
The highest-performance engineering plastic — extreme heat resistance, chemical inertness, and biocompatibility. Used in aerospace, medical implants, and semiconductor tooling.
