CNC machining works on hard metals such as stainless steel and titanium, soft metals like aluminum, copper, and brass, and plastics including ABS, polycarbonate, nylon, acrylic, etc.
Aluminum is a highly ductile metal, making it easy to machine. The material has a good strength-to-weight ratio and is available in many types for a range of applications.
Aluminum ADC12 (A380)
Copper displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.
- Copper 101
- Copper for EDM
- Beryllium copper
- Chromium zirconium copper
- Tungsten copper
- Antimony copper
Brass / Bronze
Brass has desirable properties for a number of applications. It is low friction, has excellent electrical conductivity and has a golden (brass) appearance.
- Brass 2680
- Brass H59

RapidDirect provides surface finishes on all CNC parts, including anodizing, electroplating, bead blasting, polishing, brushing, powder coating, and painting.
Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.
Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.
Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.
Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.
Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. Most commonly applied to aluminum.
Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.
Our standard tolerances for CNC machining of metals is DIN-2768-1-fine and for plastics is DIN-2768-1-medium. Tolerances are greatly affected by part geometry and type of material. Our project managers will consult with you on every part of your project and will seek to provide the highest degree of precision possible.
Our CNC machining service is ideal for rapid tooling and can be used with almost any material. At RapidDirect, we specialize in the production of high quality tools used in injection molding and other tooling applications.
CNC Machining is ideal for prototyping applications for a number of reasons: it is compatible with a broad range of cost-effective materials, it produces precise parts and prototype turnaround times are rapid. We work with our customers to design and produce prototypes that meet their manufacturing requirements and quality standards.
CNC Machining is commonly used for end-use production because of its precision, high-quality finishes and broad material compatibility. At RapidDirect, we offer customers a range of end-use materials, including plastics, aluminum and brass. We also provide the option to work with custom raw materials.
Quality Reports & Certifications
Full dimensional report
Details of all required part dimensions accompany the part, giving you peace of mind that the part will function and fit as designed.
We provide material certification with our products, providing traceability to material characteristics.
First part verification
We can ship two sets of parts to the customer for verification on your request. Once the parts have been validated, we can move into full production.
