CNC Machining for Multiple Materials

HUANG LIANG PRECISION is a machining parts factory offering a choice of metals and engineering plastics to suit your component’s function and operating environment. Our material capabilities include:

  • Carbon steel and alloy steel machining
  • stainless steel cnc machining
  • aluminum alloy cnc machining
  • copper cnc machining
  • cnc titanium machining
  • Engineering plastics machining

Tool selection, cutting parameters, and operation sequences are adapted to each material. This approach helps control workpiece distortion, tool wear, and dimensional variation while maintaining consistent part quality throughout production.

Material Options for Your Machined Components

Hardness, toughness, thermal conductivity, and machinability all influence how a component is produced. HUANG LIANG PRECISION works with the materials below, matching machining conditions to the selected grade and your part requirements.

Carbon, Alloy, and Free-Cutting Steels
  • Machinable steel grades include S15C, S45C, SUM24L, and AISI 12L14, covering carbon steels and free-cutting steels. Alloy steels are also available for machining.
  • Depending on the grade and heat treatment, steels offer strength, wear resistance, and mechanical properties suited to shafts, structural components, fasteners, and general machinery parts.
Stainless Steels
  • Common stainless steel grades include SUS303, SUS304, SUS316, SUS420, and SUS440C.
  • Grade selection allows buyers to balance corrosion resistance, elevated-temperature performance, strength, and hardness for medical equipment, food-processing machinery, electronics, fluid-control components, and precision mechanisms.
Aluminum Alloys
  • Available aluminum alloy grades include A2011, A6061, A7075, and A5056.
  • Low weight, machinability, and grade-dependent corrosion resistance make aluminum alloys suitable for automotive and motorcycle parts, electronic equipment, automation machinery, and lightweight structural components.
Copper and Copper Alloys
  • Material options cover copper, brass, beryllium copper, and phosphor bronze, including C1100, C3600, C3602, C3604, C6802, C17200, C5191, and C5210.
  • These materials offer different combinations of electrical conductivity, wear resistance, spring properties, and machinability. Typical applications include electrical terminals, connectors, hardware, bearings, and precision mechanical parts.
Commercially Pure Titanium and Titanium Alloys
  • Titanium machining options include commercially pure titanium grades CP1 through CP4 and alloys such as Ti-6Al-4V.
  • Titanium combines low density and corrosion resistance, while alloy grades such as Ti-6Al-4V provide high strength-to-weight ratios. Applications include aerospace components, medical devices, performance-critical equipment, and precision parts exposed to demanding environments.
Engineering Plastics
  • Machinable engineering plastics include POM, PTFE, and PEEK.
  • Depending on the polymer, useful properties include low weight, chemical resistance, low friction, and elevated-temperature capability. Typical parts include seals, power-transmission components, electrical insulators, and components for medical and electronic equipment.
