Brass

Brass workpiece brass is recognized as one of the simplest and most cost-effective materials in CNC milling. It is an alloy of copper and zinc, which is stable but not strong enough. Common uses include medical equipment, consumer goods, and electrical hardware and contacts. Because brass also has a low friction coefficient and high corrosion resistance, they are also used in engineering, piping, steam engineering, and even musical instruments. Because its material is soft and easy to process, it is used in plumbing accessories, home decoration, musical instruments, etc.

With good machinability and excellent conductivity, it is very suitable for applications requiring low friction. It is also commonly used in architecture to produce a golden appearance with an aesthetic appearance.

Brass c36000 is a material with high tensile strength and natural corrosion resistance. It is one of the easiest materials to process, so it is usually used in mass applications.

Copper

In terms of brass CNC milling materials, few metals can provide copper conductivity. High corrosion resistance helps this material prevent rust, while thermal conductivity makes the forming process easier during CNC milling. Usually used in the automotive industry, applications include cooling systems and heat exchangers, as well as various engineering applications, such as valves and radiators. However, it is important to know that copper is weak against certain chemicals such as acids, sulfide halogens, and ammonia solutions.

Plastic

In addition to metal materials, sans high-precision CNC processing services are also compatible with a variety of plastics. The following are some of the most widely used plastics for CNC milling technology.

ABS

ABS is one of the most common thermoplastic materials with good mechanical properties, excellent impact strength, high heat resistance, and good machinability.

ABS has a low density, making it ideal for lightweight applications. CNC machined milled ABS parts are often used as prototypes before mass production via injection molding.

Nylon CNC machining and milling

Nylon, also known as polyamide (PA), is a thermoplastic. Due to its excellent mechanical properties, good impact strength, high chemical and abrasion resistance, and also moderate flame retardancy, common uses include insulators, bearings, and short-run products that will be used for injection molding. The disadvantage is that it is easy to absorb water and moisture.

POM

POM is also known as Delrin. It is an engineering thermoplastic with the highest processability among plastics.

POM (Delrin) is usually the best choice for CNC machining and milling of plastic parts that require high precision, high stiffness, low friction, excellent dimensional stability at high temperature, and very low water absorption.

Teflon

PTFE, commonly known as polytetrafluoroethylene (Teflon), is an engineering thermoplastic with excellent chemical and thermal resistance and the lowest coefficient of friction of any known solid. It is an excellent electrical insulator. However, it has purely mechanical properties and is often used as a lining or insert for components.

High-density polyethylene

High-density polyethylene (HDPE) is a thermoplastic with a high strength-to-weight ratio, high impact strength, and good weather resistance.

HDPE is a lightweight thermoplastic suitable for outdoor use and pipe transport. Like ABS, it is often used to create prototypes before injection molding.
