| Material | Common grades | Machinability | Used in | Finishes |
|---|---|---|---|---|
| AluminiumHigh machinability and ductility, good strength-to-weight ratio. | 6061-T6, 7075-T6, 5052, Other grades on request | Aluminium is the fastest metal to machine well: it cuts at high spindle speeds and feeds, evacuates chips cleanly, and puts little wear on tooling. | Automotive, Semiconductor, Optics | Anodizing (Type II), Hardcoat anodizing (Type III), Chemical film (chromate conversion) |
| Stainless steelHigh tensile strength, corrosion and temperature resistant. | 303, 304, 316L, 17-4 PH | Stainless steels work-harden: if a cutting edge rubs instead of cutting, the surface hardens ahead of the tool and finishes deteriorate. | Medical, Oil & Gas, Semiconductor | Passivation, Electropolishing, Bead blasting |
| Mild steelHigh machinability and weldability, high stiffness. | 1018 / S20C, 1045 / S45C, 12L14, S355 / A36 plate | Mild steel is the economical workhorse: low material cost, predictable cutting, good weldability. | Automotive, Oil & Gas | Zinc plating, Black oxide, Phosphate coating |
| BrassLow friction, excellent electrical conductivity, golden appearance. | C360 (free-machining), C260 (cartridge brass), Naval brass / dezincification-resistant grades | C360 free-machining brass is the benchmark other metals are measured against; it machines faster than any common engineering metal, producing fine ch… | Oil & Gas, Automotive | Polishing, Nickel or chrome plating, Tin plating |
| CopperExcellent thermal and electrical conductivity. | C110 (ETP), C101 (OFHC), C145 (tellurium copper) | Pure copper is gummy to machine: it is soft, ductile, and wants to form long stringy chips and built-up edge on the tool. | Semiconductor, Automotive | Tin plating, Nickel plating, Silver plating |
| Alloy steelHigh strength and toughness, fatigue resistant. | 4140 / EN19 (chromoly), 4340 / EN24, 8620, Other grades on request | Alloy steels machine predictably in the annealed or normalized condition, and pre-hardened grades such as 4140HT (around 28–32 HRC) can be milled and… | Oil & Gas, Semiconductor, Automotive | Black oxide, Zinc or nickel plating, Phosphate coating |
| Tool steelHigh hardness and stiffness, abrasion resistant. | O1, A2, D2, H13 | Tool steels are machined in the annealed state, heat treated to working hardness, then finish-ground on critical features; sequencing that discipline… | Automotive, Semiconductor | Heat treatment, Precision grinding, Black oxide |
| TitaniumExcellent strength to weight ratio, used in medical, automotive and precision engineering industries. | Grade 2 (commercially pure), Ti-6Al-4V (Grade 5), Ti-6Al-4V ELI (Grade 23) | Titanium demands respect at the machine: it conducts heat poorly, so cutting heat concentrates in the tool edge instead of the chip, and it springs b… | Automotive, Medical | Bead blasting, Titanium anodizing, Passivation |
| InconelHigh-strength and corrosion-resistant nickel alloy. | Inconel 625, Inconel 718 | Inconel is among the hardest materials to machine commercially: it work-hardens aggressively, keeps its strength at cutting temperatures, and abrades… | Automotive, Oil & Gas | Precision grinding, Bead blasting, Passivation / pickling |
| InvarNickel alloy with a very low coefficient of thermal expansion. | Invar 36, Super Invar | Invar exists for one property: a coefficient of thermal expansion close to one-tenth of steel's. | Optics, Semiconductor | Stress-relief / stabilization cycles, Nickel plating, Black oxide |
Metal Machining Capabilities & Material Families
Our multi-axis CNC milling and turning centers process a comprehensive range of non-ferrous alloys, stainless steels, and high-temperature superalloys:
Aluminium Alloys (6061-T6, 7075-T6, 5052, 6082, 2024)
Aluminium provides excellent strength-to-weight ratios, rapid machining cycle times, and compatibility with anodizing and chemical film coatings. 6061-T6 is the industry standard for electronic enclosures, brackets, and semiconductor tooling. 7075-T6 offers high yield strength approaching structural steel, making it ideal for high-stress robotic fittings, automotive components, and high-load structural members.
Stainless Steels (303, 304/304L, 316/316L, 17-4 PH, 440C)
Austenitic grades (304, 316L) deliver high corrosion resistance for marine, food processing, and medical device applications. Precipitation-hardening stainless steel (17-4 PH) combines high mechanical strength with moderate corrosion resistance, frequently specified for precision actuator shafts, automotive gears, and high-pressure valve components.
Titanium (Ti-6Al-4V Grade 5, Grade 2)
Titanium alloys combine high tensile strength, low density, superior fatigue resistance, and biocompatibility. We utilize dedicated rigid tooling and through-spindle coolant to machine titanium components for structural fasteners, lightweight robotics, and medical implants.
Nickel Superalloys (Inconel 718, Inconel 625, Hastelloy, Monel)
Engineered for extreme operating environments, Inconel alloys retain tensile strength and oxidation resistance at temperatures exceeding 650°C. We maintain proven toolpath parameters and carbide tooling to machine high-pressure oilfield valve bodies, downhole sensors, and high-temperature power components.
Controlled-Expansion Alloys (Invar 36)
Invar 36 features a near-zero coefficient of thermal expansion, making it essential for laser cavities, optomechanical benches, and dimensional metrology standards that must not drift under fluctuating ambient temperatures.
Tool Steels & Alloy Steels (4140, 4340, D2, A2, O1, H13)
Heat-treatable alloy and tool steels provide high surface hardness, fatigue resistance, and toughness for stamping dies, forming punches, shafts, and heavy-duty drivetrain parts.
Quality Assurance & Material Traceability
Every metal order is tracked against incoming mill test certificates (EN 10204 3.1) confirming chemical composition and mechanical properties. Dimensional features are verified on Zeiss coordinate measuring machines and optical SmartScopes.
