CNC Machining Materials
Choose from 30+ CNC machining materials to match your project’s functional and aesthetic requirements. From aluminum, steel, and brass to advanced plastics, we provide high-quality materials for your custom CNC parts.

Metal Components
QBH offers precision CNC machining for a wide range of metal materials. Our portfolio includes Aluminium (lightweight and corrosion-resistant), Copper (excellent thermal and electrical conductivity), Bronze (wear-resistant and good for bushings), Steel and Stainless Steel (high strength and durability), Magnesium (ultra-lightweight for aerospace), and Titanium (superior strength-to-weight ratio and biocompatibility). Whether you need functional prototypes, end-use parts, or complex metal components with tight tolerances, our CNC machining services deliver high-quality results with fast lead times.

Plastic Components
QBH also offers precision CNC machining for a wide variety of plastic materials, including ABS, PC, PMMA (acrylic), PA (nylon), PEEK, PP, PE, HDPE, LDPE, PPS, PVC, PTFE (Teflon), UPE, Bakelite, and FR-4. These materials provide properties such as impact resistance, optical clarity, chemical resistance, high-temperature performance, and electrical insulation. Our CNC plastic machining delivers tight tolerances and smooth surface finishes for functional prototypes, custom fixtures, and end-use parts with fast lead times.
