What are the recommendations for materials suitable for the semiconductor industry?
Advantages of using this material



  • Aluminum
  • Stainless steel
  • Brass
  • Bronze
  • Copper
  • Cast iron
  • Titanium


Aluminum is one of the most commonly used metals in the world because of its excellent strength-to-weight ratio, low cost, and recyclability. Jinming offers multiple aluminum alloys such as 2024, 5052, 6061, 6063, 7050, 7075 and so on, as a high-quality silver metal that’s soft, lightweight and durable, it is commonly used for 5-axis CNC machining in military and aerospace applications.

Stainless steel

Stainless steel is highly resistant to corrosion and rust, making it a popular industrial alloy used in a wide variety of industries. Stainless steel is used to manufacture handles, medical devices, lab instruments, automotive parts, weld ferrules, and more. Jinming offers multiple stainless steel such as 303,304, 316,17-4PH, 4130, 4140 and so on.


Brass is a metal alloy made of copper and zinc, brass has decent strength, electrical conductivity, and minimal tool wear. It is commonly used for a variety of parts such as gears, lock components, pipe fittings, and ornamental applications.


Bronze is an alloy comprised of copper and tin, and it offers a wide range of properties such as good wear and corrosion resistance, high ductility, hardness, thermal conductivity and strength. Bronze is often used to manufacture nuts, bolts, threaded parts, bearings, bushings, screws, and more.


Copper is a common metal offering excellent thermal and electrical conductivity, which make them natural choices for wiring, motors and other electrical applications.

Cast iron

Cast iron is a dependable wear-resistant material which machines faster than many steel varieties. This is an ideal material for absorbing vibrations. Parts commonly made with cast iron include gears, bases, pulleys and bushings.


Titanium is an element alloyed with iron, aluminum, vanadium, and molybdenum, with good corrosion resistance and the ability to be welded. Common use cases include aerospace fasteners, turbine blades, engine components, sports equipment and marine applications.

  • ABS
  • PMMA
  • PC
  • PPS
  • Delrin
  • PEEK
  • Garolite


ABS is a low-cost engineering plastic, widely used for pre-injection molding prototypes. CNC machined ABS is a great option for production-like parts, where detail and mechanical properties are important.


Acrylic is known as PMMA, an abbreviation of its full chemical name, polymethyl methacrylate. It is a scratch-resistant plastic, available optically clear or opaque. It is often used for tanks, panels, and optical applications.  It can be somewhat brittle in thin walled areas, so it is not recommended for delicate or complex geometries.


Polycarbonate (known also by the abbreviation PC) is one of the most common plastics used in manufacturing.
It is heat-resistant, impact-resistant, flame-retardant, and one of the most recycled plastics in the world. Famous examples of the material are first-generation MacBook laptops, safety goggles, and optical disks.


Polyphenylene Sulfide (PPS) is a high-performance engineering plastic with excellent temperature resistance, dimensional stability, and electrical insulation properties. With exceptional mechanical strength, chemical resistance, and flame resistance, PPS is commonly found in high temperature applications such as automotive parts, appliances, electronics, medical devices, and industrial applications.


Delrin (generic: acetal) is a low-friction, high-stiffness material, with a relatively high toughness and minimal elongation, Delrin boasts excellent dimensional accuracy. It is used in applications ranging from auto parts to musical instruments.


In high-stress/high-temperature applications, PEEK is a great lightweight substitute for most soft metals. Additionally, PEEK is resistant to moisture, wear, and chemicals. Glass-filled PEEK is a high performance plastic with excellent rigidity, strength and toughness. The addition of glass fibers enhances its ability to maintain dimensional stability even in harsh thermal and chemical environments. This material is often used in the following industries: aircraft, automotive, medical, chemical, semiconductor and microwave.


Garolite(also known as phenolic and epoxy-grade industrial laminate) is a composite material with a low coefficient of thermal expansion. Additionally, it does not absorb water and is an excellent insulator, which makes it really useful for electronics applications.
