Aluminum alloys combine lightweight properties, high specific strength, excellent machinability, and superior corrosion resistance, making them the most commonly used metal material in CNC machining and small-batch manufacturing.

Stainless steel combines high strength, excellent corrosion resistance, and broad surface finish compatibility, making it one of the most specified metals in precision CNC machining. With grades ranging from free-cutting 303 to marine-grade 316L and high-strength 17-4PH, stainless covers demanding environments from food processing and medical devices to offshore hardware — where bare aluminum or carbon steel would fail without coating.

Brass offers the best machinability of any common metal alongside natural corrosion resistance and excellent thread quality, making it the go-to material for precision fittings, valves, and threaded connectors. Compatible with nickel, chrome, and gold plating for both functional and decorative finishes.

Titanium delivers the highest strength-to-weight ratio of any structural metal at roughly half the density of steel, with a corrosion resistance that exceeds 316L stainless in chloride and acidic environments. Biocompatible and radiolucent, Ti-6Al-4V ELI is the standard for orthopedic implants and surgical instruments — making titanium the material of choice where strength, weight, and corrosion resistance must all be met simultaneously.

Carbon steel delivers reliable structural strength at the lowest material and machining cost of any metal, with a grade range spanning from free-cutting 1018 for general structural parts to heat-treatable 4140 and 4340 for high-load shafts, gears, and machine components — the default choice wherever corrosion protection is manageable and cost per part matters.

Alloy steel combines high strength, heat treatability, and wear resistance that carbon steel alone cannot achieve — through-hardenable to 50–65 HRC for demanding structural, tooling, and die applications. We provide and machine different types of alloy and tool steel grades , covering gears, shafts, mold inserts and dies.

Zinc alloys offer the lowest die casting cost of any common metal, with excellent fluidity for thin walls and complex near-net-shape geometry that reduces machining stock. We supply zinc alloy parts as die cast billets with post-machining to ±0.005 mm on precision features, and coordinate electroplating — chrome, nickel, and copper — which adheres to zinc substrates better than any other die casting metal.

Inconel and nickel superalloys retain mechanical strength at temperatures up to 1,090°C and resist corrosion in oxidizing, acidic, and seawater environments where stainless steel and titanium cannot perform. We machine the full range of superalloy grades for turbine components, exhaust systems, chemical reactor internals, and subsea hardware using CBN tooling and high-pressure coolant strategies specific to each alloy.

Invar 36 is a nickel-iron alloy with a coefficient of thermal expansion of approximately 1.2 ppm/°C — roughly 10× lower than carbon steel — maintaining dimensional stability from cryogenic temperatures to 230°C. We machine Invar 36 for aerospace composite tooling, optical mounts, laser cavity components, and precision measurement equipment where dimensional change due to temperature variation cannot be tolerated.

ABS combines good impact resistance, easy machinability, and broad finishing compatibility — accepting paint, adhesives, solvent bonding, and direct electroplating. We machine ABS for housings, enclosures, and appearance parts where low per-part cost and surface finish flexibility matter more than high mechanical strength.

POM combines low friction, excellent dimensional stability, and good fatigue resistance — gears, bushings, and sliding components run without lubrication and hold tight tolerances in humid environments due to minimal moisture absorption. We machine POM for precision mechanical parts where dimensional consistency in service is the primary requirement.

Polycarbonate combines optical clarity with the highest impact resistance of any transparent plastic and heat resistance to 130°C continuous — outperforming both ABS and acrylic where transparency, toughness, and thermal performance must be met simultaneously. We machine PC for transparent windows, safety shields and structural housings.

Nylon combines good mechanical strength, self-lubricating wear resistance, and broad chemical compatibility — with continuous use temperature to 120°C that exceeds POM, ABS, and PC. We machine PA6, PA66, glass-filled, and specialty nylon grades for gears, bearings, structural brackets, and fluid handling components where temperature and chemical resistance matter more than dimensional stability in humid conditions.

PVC offers broad chemical resistance to acids, alkalis, and salts alongside inherent flame retardancy and good electrical insulation — without surface coating or additives. We machine rigid PVC for chemical handling equipment, electrical components, and fluid system fitting.

Acrylic delivers 92% light transmission, superior UV stability, and better scratch resistance than polycarbonate — maintaining optical clarity outdoors without yellowing or coating. We machine PMMA for display covers, light guides, optical components, and decorative panels where clarity and surface quality take priority over impact resistance.

PEEK delivers continuous use temperature to 250°C, tensile strength rivaling aluminum alloys, and chemical resistance comparable to PTFE — the only common thermoplastic that combines all three simultaneously. We machine PEEK for medical implants, aerospace components, semiconductor equipment, and chemical processing parts where no lower-cost plastic can meet the combined performance requirements.

PTFE resists virtually all chemicals, has the lowest coefficient of friction of any solid material, and operates continuously from -200°C to +260°C — the widest temperature range of any common plastic. We machine virgin and filled PTFE grades for seals, gaskets, bearings, and chemical handling components.
