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, resistência à corrosão, condutividade, resistência ao calor, tolerance stability, acabamento superficial, e requisitos de inspeção.
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, impacto final, tolerance stability, and inspection needs before sending an RFQ.
Usinagem CNC de metais
Metal CNC machined parts are commonly made from aluminum, aço inoxidável, cobre, latão, titânio, and alloy steel when strength, rigidez, condutividade, resistência ao calor, resistência à corrosão, or dimensional stability is required. JADE-CNC can review aluminum CNC machining, stainless steel machining, copper machining, usinagem de titânio, alloy machining, and related finishing or inspection requirements according to the drawing.
Usinagem CNC de Superliga
High-temperature and corrosion-resistant alloys may be selected for demanding industrial parts when strength, resistência ao calor, and inspection requirements justify the machining difficulty. JADE-CNC reviews tooling, cutting strategy, and quality requirements before quotation.
Usinagem CNC de dissipador de calor
Heat sink materials and geometry affect thermal performance, machining cost, acabamento superficial, e montagem. JADE-CNC reviews fins, channels, planicidade, material, and finish requirements before machining heat sink components.
Usinagem CNC de liga Kovar
Kovar alloy is used when controlled thermal expansion is important for glass, ceramic, or semiconductor-related assemblies. Drawing requirements, controle de tolerância, and inspection should be reviewed before machining.
Usinagem CNC de plástico
Engineering plastics such as ABS, acrylic, polycarbonate, nylon, ESPIAR, PTFE, and acetal can be used for plastic machining when lightweight, isolante, transparente, chemically resistant, or low-friction parts are required. Material stability, moisture absorption, controle de rebarbas, acabamento superficial, and tolerance behavior should be reviewed early.
One-Stop CNC Machining Solution
For projects that need machining, acabamento, inspeção, and assembly support, JADE-CNC coordinates the manufacturing workflow so drawings, requisitos de materiais, acabamento superficial, quality checks, and delivery expectations stay aligned.
CNC Machining Material Selection Guide
Material selection affects machining cost, estabilidade dimensional, acabamento superficial, força, peso, resistência à corrosão, condutividade, e inspeção final. JADE-CNC can review material options based on the drawing, part function, production quantity, requisito de acabamento, and application environment.

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, machining method, tolerance requirement, acabamento superficial, application environment, e necessidades de inspeção.
Material Function
JADE-CNC reviews whether the part needs strength, baixo peso, resistência à corrosão, condutividade elétrica, resistência ao calor, resistência ao desgaste, isolamento, or dimensional stability.
Usinabilidade
Different metals and plastics affect tool wear, velocidade de corte, controle de rebarbas, surface quality, and machining cost. The machining route should match the material behavior.
Tolerance Stability
Material stress, espessura da parede, tratamento térmico, moisture absorption, and part geometry can affect dimensional stability during and after machining.
Surface Finish Compatibility
Anodização, chapeamento, passivação, polimento, jateamento de contas, pintura, 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, confirmação de materiais, and documentation requirements.
Common CNC machining materials include aluminum, aço inoxidável, carbon steel, liga de aço, cobre, latão, titânio, POM, ESPIAR, PTFE, PC, ABS, acrylic, nylon, e outros plásticos de engenharia.
Start from the part function. Força, peso, resistência à corrosão, condutividade, resistência ao calor, tolerance stability, acabamento superficial, 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, usinabilidade, resistência à corrosão, and finishing behavior.
Stainless steel is often selected when corrosion resistance, força, resistência ao desgaste, 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, thermal conductivity, or stable machining of small turned features is important.
Sim. POM, ESPIAR, PTFE, PC, ABS, acrylic, nylon, and other plastics can be CNC machined, but material movement, controle de rebarbas, moisture absorption, and tolerance behavior should be reviewed.
Sim. Material cost, usinabilidade, desgaste da ferramenta, setup difficulty, finishing requirements, and inspection needs all affect CNC machining cost.
Sim. Anodização, chapeamento, passivação, polimento, jateamento de contas, pintura, and coating results depend on material grade, condição da superfície, geometria, e requisitos de mascaramento.
Customer-supplied materials can be reviewed when material grade, formulário de estoque, necessidades de certificação, subsídio de usinagem, and handling requirements are clear.
Please send 3D CAD files, 2Desenhos D, material grade or preferred options, application environment, notas de tolerância, requisitos de acabamento superficial, quantidade, e necessidades de inspeção.
