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.
