Materials Suitable for 5-Axis CNC Machining
As a project engineer at BERGEK, an ISO 9001 certified 5-axis CNC machining manufacturer, I am frequently asked by customers which materials can be effectively machined using 5-axis technology. Selecting the right material is critical for the performance, cost, and lead time of any precision part. With modern 5-axis CNC machining, we can deliver complex, tight-tolerance components in a broad range of high-performance metals and selected plastics—always under the strictest quality controls.
1. Aluminum Alloys
BERGEK is an ISO 9001 certified aluminum CNC machining manufacturer, specializing in alloys like 6061, 6082, 7075, and 2024.
Why aluminum?
- Lightweight, high strength-to-weight ratio
- Excellent machinability—ideal for prototyping and high-volume production
- Common in aerospace structures, automotive housings, and electronic enclosures
- Supports advanced finishes: anodizing, powder coating
2. Titanium Alloys
As an ISO 9001 certified titanium alloy CNC machining manufacturer, we regularly machine grades like Ti-6Al-4V (Grade 5) and Grade 2 titanium.
Why titanium?
- Outstanding strength, corrosion resistance, and biocompatibility
- Widely used in aerospace, medical implants, and performance automotive parts
- 5-axis machining enables the complex geometries titanium demands while keeping tolerances within ±0.01mm
3. Stainless Steels
Our team is a recognized ISO 9001 certified stainless steel CNC machining manufacturer, working with grades such as 303, 304, 316, and 17-4PH.
Why stainless steel?
- Superior corrosion resistance, high strength, excellent wear performance
- Used for medical instruments, precision mechanical parts, food-grade components
- Multi-axis CNC machining ensures flawless finishes and reliable assembly fit
4. High-Performance Superalloys (Inconel, etc.)
For clients in the energy, aerospace, and defense sectors, we also offer expertise as an ISO 9001 certified Inconel CNC machining specialist.
- Inconel 718, 625 and similar superalloys can withstand extreme heat, corrosion, and mechanical stress
- Demanding for machinists, but 5-axis equipment allows for accurate and consistent results in complex geometries
5. Brass, Copper, and Specialty Materials
Our multi-axis CNC machining capability extends to brass, copper, and select high-performance plastics (POM, PTFE, peek).
- Brass and copper offer high electrical conductivity, ideal for electronics and connectors
- Certain engineering plastics can be CNC machined for prototypes and low-stress components, though metal parts remain our core business
Industry Application Examples
- Aerospace CNC machining materials: Aluminum and titanium for structural and engine parts
- Automotive CNC machining materials: Aluminum, stainless steel, and titanium for drive, chassis, and engine systems
- Medical device CNC machining materials: Titanium and stainless steel for implants, surgical tools, and housings
Quality and Traceability
Every order at BERGEK is delivered with full ISO 9001 CNC machining manufacturer documentation, batch traceability, and dimensional inspection. As an ISO certified CNC supplier with global experience, we ensure every material is sourced and processed to meet the most demanding specifications in precision engineering.
If your next project requires custom CNC parts made from high-performance metals and complex alloys, BERGEK has the multi-axis equipment, material expertise, and process control to deliver results you can trust—on time and to spec.
