CNC Machining Materials Guide
Use this CNC machining materials guide to compare metal and plastic options for custom machined parts. Material choice affects strength, peso, resistenza alla corrosione, conduttività, resistenza al calore, tolerance stability, finitura superficiale, e requisiti di ispezione.
Common CNC Machining Materials Used by JADE-CNC
JADE-CNC manufactures prototype and production parts from commercially available metal CNC machining materials and plastic CNC machining materials, and can also review customer-supplied materials when required. This material guide helps buyers compare CNC material properties, machining behavior, finishing impact, tolerance stability, and inspection needs before sending an RFQ.
Lavorazione CNC dei metalli
Metal CNC machined parts are commonly made from aluminum, acciaio inossidabile, rame, ottone, titanio, and alloy steel when strength, rigidità, conduttività, resistenza al calore, resistenza alla corrosione, or dimensional stability is required. JADE-CNC can review aluminum CNC machining, stainless steel machining, copper machining, lavorazione del titanio, alloy machining, and related finishing or inspection requirements according to the drawing.
Lavorazione CNC di superleghe
High-temperature and corrosion-resistant alloys may be selected for demanding industrial parts when strength, resistenza al calore, and inspection requirements justify the machining difficulty. JADE-CNC reviews tooling, cutting strategy, and quality requirements before quotation.
Lavorazione CNC del dissipatore di calore
Heat sink materials and geometry affect thermal performance, machining cost, finitura superficiale, e assemblaggio. JADE-CNC reviews fins, channels, planarità, materiale, and finish requirements before machining heat sink components.
Lavorazione CNC in lega Kovar
Kovar alloy is used when controlled thermal expansion is important for glass, ceramic, or semiconductor-related assemblies. Drawing requirements, controllo della tolleranza, and inspection should be reviewed before machining.
Lavorazione CNC della plastica
Engineering plastics such as ABS, acrilico, policarbonato, nylon, SBIRCIARE, PTFE, and acetal can be used for plastic machining when lightweight, isolante, trasparente, chemically resistant, or low-friction parts are required. Stabilità del materiale, moisture absorption, controllo delle bave, finitura superficiale, and tolerance behavior should be reviewed early.
Soluzione di lavorazione CNC completa
For projects that need machining, finitura, ispezione, and assembly support, JADE-CNC coordinates the manufacturing workflow so drawings, requisiti materiali, finitura superficiale, quality checks, and delivery expectations stay aligned.
Guida alla selezione dei materiali per la lavorazione CNC
Material selection affects machining cost, stabilità dimensionale, finitura superficiale, forza, peso, resistenza alla corrosione, conduttività, e ispezione finale. JADE-CNC can review material options based on the drawing, funzione della parte, quantità di produzione, requisito di finitura, and application environment.
| Materiale | Categoria | Proprietà chiave | Lavorabilità | Typical CNC Applications | Opzioni di finitura superficiale |
|---|---|---|---|---|---|
| Alluminio 6061-T6 | Alluminio | General-purpose, leggero, resistente alla corrosione | Eccellente | Alloggiamenti, parentesi, infissi, communication parts | Anodizzazione, sabbiatura, verniciatura a polvere |
| Aluminum 7075-T6 | Alluminio | High strength-to-weight ratio | Bene | Structural brackets, componenti della robotica, precision frames | Anodizzazione dura, sabbiatura |
| Acciaio inossidabile 304 | Acciaio inossidabile | Corrosion resistant, widely available | Medio | Industrial parts, medical device components, infissi | Passivazione, lucidatura, sabbiatura |
| Acciaio inossidabile 316 | Acciaio inossidabile | Better corrosion resistance in harsh environments | Medio | Medico, marino, chemical-exposure components | Passivazione, electropolishing |
| Acciaio al carbonio 1018 | Acciaio al carbonio | Low carbon, conveniente, facile da lavorare | Eccellente | General machinery parts, piatti, alberi | Black oxide, zinc plating, pittura |

What JADE-CNC Reviews Before CNC Material Selection
Choosing a CNC machining material is not only about selecting a grade from a list. The right material should match the part function, metodo di lavorazione, tolerance requirement, finitura superficiale, application environment, e le esigenze di ispezione.
Material Function
JADE-CNC reviews whether the part needs strength, peso ridotto, resistenza alla corrosione, conduttività elettrica, resistenza al calore, resistenza all'usura, isolamento, or dimensional stability.
Lavorabilità
Different metals and plastics affect tool wear, velocità di taglio, controllo delle bave, surface quality, and machining cost. The machining route should match the material behavior.
Tolerance Stability
Material stress, spessore della parete, trattamento termico, moisture absorption, and part geometry can affect dimensional stability during and after machining.
Surface Finish Compatibility
Anodizzazione, placcatura, passivazione, lucidatura, sabbiatura, pittura, and coating requirements should be checked against the selected material and functional surfaces.
Inspection and Traceability
For projects that need reports or material records, JADE-CNC can coordinate dimensional checks, selected feature inspection, material confirmation, e requisiti di documentazione.
Common CNC machining materials include aluminum, acciaio inossidabile, carbon steel, acciaio legato, rame, ottone, titanio, POM, SBIRCIARE, PTFE, computer, ABS, acrilico, nylon, e altri tecnopolimeri.
Start from the part function. Forza, peso, resistenza alla corrosione, conduttività, resistenza al calore, tolerance stability, finitura superficiale, and inspection requirements should be considered together.
Common aluminum grades include 6061, 7075, 2024, 5052, 6063, and MIC-6 tooling plate. Each grade has different strength, lavorabilità, resistenza alla corrosione, and finishing behavior.
Stainless steel is often selected when corrosion resistance, forza, resistenza all'usura, or appearance is important. 304 E 316 are common options for CNC machined stainless steel parts.
Copper and brass are often used when electrical conductivity, conduttività termica, or stable machining of small turned features is important.
SÌ. POM, SBIRCIARE, PTFE, computer, ABS, acrilico, nylon, and other plastics can be CNC machined, but material movement, controllo delle bave, moisture absorption, and tolerance behavior should be reviewed.
SÌ. Costo del materiale, lavorabilità, usura degli utensili, setup difficulty, requisiti di finitura, and inspection needs all affect CNC machining cost.
SÌ. Anodizzazione, placcatura, passivazione, lucidatura, sabbiatura, pittura, and coating results depend on material grade, condizione della superficie, geometria, e requisiti di mascheramento.
Customer-supplied materials can be reviewed when material grade, modulo di riserva, certification needs, sovrametallo di lavorazione, and handling requirements are clear.
Please send 3D CAD files, 2disegni D, material grade or preferred options, application environment, note di tolleranza, surface finish requirements, quantità, e le esigenze di ispezione.
