Materials

Yonglihao Machinery helps you choose materials that fit real manufacturing results. We do not just list generic properties. We focus on what matters for your part. This includes its function, tolerance risk, surface needs, and cost. Browse the categories below. If you share your drawing and requirements, we will confirm the best material and process route during our DFM review.

CNC Machining Materials

CNC machining works best when the material matches your part’s function and tolerance needs. Below are the most common CNC materials we support. We group them into metals and plastics so you can choose faster. We confirm the final grade and machining approach during the DFM review.

Metal CNC Machining

We provide common metal options for CNC machining. These materials support prototypes and production parts. They suit everything from structural brackets to precision interfaces. A material’s grade and condition can affect machinability, finish, and tolerance. We confirm your needs during our DFM review before production.

Plastic CNC Machining

We also offer engineering plastics for CNC machining. These are good for lightweight designs or when you need insulation, corrosion resistance, or low friction. Plastics can be sensitive to heat, moisture, and clamping forces. We review your drawing, tolerances, and operating environment to select the most stable option.

Metal Stamping Materials

We provide metal stamping services using common sheet and coil materials. This works for functional parts and cost-sensitive volume production. Our material options focus on stable forming, consistent tolerances, and clean assembly. Results depend on thickness, temper, and springback. Before tooling, we will confirm the material condition, burr direction, surface protection, and any coating needs.

FAQ

Start with the part’s function, load, and environment. Consider factors like corrosion, temperature, and chemicals. Also, think about your tolerance needs. If you share your drawing, we can recommend the best material and process during our DFM review.

We can do both, depending on the material and project. For production orders, we confirm availability, lead time, and preferred grades before we start.

Yes, in many cases. Please provide the grade information and any needed certificates. We will review the material’s condition and suitability before we begin.

Grade and condition can change how a material machines or forms. They also affect surface finish and dimensional stability. We confirm the exact grade, temper, or condition during our review, especially for tight tolerances.

Tolerance capability depends on the specific feature. It is also affected by material behavior and part geometry. We confirm achievable tolerances after our DFM review. We then define inspection methods for critical dimensions.

Often, yes. Some plastics are sensitive to heat, moisture, and clamping force. This can affect stability. We will recommend the most stable plastic and machining approach for your application.

We can provide material certificates when required and available. Please tell us your documentation needs when you request a quote. This allows us to align sourcing and records.

This page groups materials by process, like CNC machining and metal stamping. If your project needs casting, welding, bending, laser cutting, or wire EDM, send us your details. We will confirm the best material and process for you.

Yes. If a certain grade is unavailable or too costly, we can suggest alternatives. These will still meet your functional needs. We will also confirm any impact on performance and finishing.

Send your 2D and 3D files. Include the target material, quantity, and critical tolerances. Also, provide surface finish needs and the operating environment. This helps us give you a reliable recommendation quickly.
