CNC Machining Materials

Material Selection for Precision Machining

Selecting the optimal alloy or polymer requires balancing mechanical yield strength, thermal expansion, corrosion resistance, machinability, and post-machining surface treatments.

Metals & Superalloys

Our metal machining capabilities range from high-grade engineering aluminiums (6061-T6, 7075-T6) to high-temperature nickel superalloys and controlled-expansion metals. Stainless steels such as 316L and 17-4 PH provide corrosion resistance and high tensile strength. Titanium Ti-6Al-4V offers high strength-to-weight performance for lightweight structural frames and biocompatible medical instruments. For optical laser benches and metrology fixtures requiring sub-micron dimensional stability across temperature swings, we machine Invar 36. For extreme downhole and turbine applications, we run Inconel 718 and 625 with rigid tooling setups.

Engineering Plastics & Polymers

For applications demanding electrical insulation, chemical inertness, or low weight, we machine high-performance engineering thermoplastics. PEEK provides high continuous operating temperatures and chemical resistance in semiconductor wafer chucks and autoclavable medical components. Delrin (POM) is ideal for low-friction precision bushings and gears. Ultem (PEI) offers high dielectric strength and flame retardance. Transparent optical components and fluidic manifolds are machined from Polycarbonate and Acrylic (PMMA) with post-machining optical polishing.

Every material batch is logged with incoming mill test certificates and heat numbers, ensuring full traceability from raw bar stock to delivered components.
