Frequently asked questions about precision fits & aluminum materials
What is ISO 286 tolerance standard?
ISO 286 defines the international system for tolerances of holes and shafts. It helps engineers calculate clearance, transition, and interference fits. Our calculator follows ISO 286 to ensure results match global engineering practices.
How do I choose the right aluminum tube or rod for my project?
The choice depends on your tolerance requirements, strength, and application. For CNC machining, precision ground bars with ±0.02 mm tolerance are ideal. For lightweight structures, thin wall tubes provide strength with reduced weight. Our team can recommend the right grade and size based on ISO standards.
Can you supply custom sizes of aluminum rods and tubes?
Yes. We manufacture customized aluminum tubes and bars according to drawings or project requirements. Large diameter tubes, rectangular profiles, and small capillaries are available with ISO-certified tolerances.
What certifications and quality standards do your products meet?
All products comply with ISO 9001 quality management and international standards such as ASTM, EN, and AMS. We also provide 3.1 material certificates and testing reports to ensure full traceability for aerospace, automotive, and industrial clients.
How fast can I get a quote and delivery?
