What is Polyamide (PA)?
Polyamide (PA), commonly known as Nylon (Nylon), is a class of high-performance synthetic engineering plastics, with its high strength, wear resistance, chemical corrosion resistance and other characteristics, become a popular choice for non-standard mechanical parts. Common types include PA6, PA66, PA12 and glass fiber reinforced (such as PA66-GF30), which can meet the needs of different working conditions.
PA Grades for Precision Machining
| Grade | Key Advantages | Applications |
| PA6 | High impact strength, easy to machine | Gears, couplings, brackets |
| PA66 | Higher heat resistance, dimensional stability | Automotive components, electrical parts |
| PA12 | Low moisture absorption, flexible | Hoses, connectors, sports equipment |
| PA46 | High stiffness at elevated temperatures | Engine parts, power tools |
| PA6/6T | Flame retardant, halogen-free | Electrical enclosures, medical devices |
Why Choose CNC Polyamide (PA) Material?
If you are looking for a reliable, durable and easy to process material to manufacture your precision parts, then PA material is definitely the right material for you!
