Frequently Asked Questions
Q: How do these bars handle galvanic corrosion when coupled with other aircraft metals?
A: We recommend surface treatments like Tagnite or Keronite (PEO coating). Use compatible fasteners and isolation methods to prevent galvanic couples with noble metals like titanium or steel. Our technical team provides specific guidance for your assembly design.
Q: Can I use these bars in commercial aircraft interiors?
A: Absolutely. Specific alloys like WE43 are engineered to pass stringent FAA flammability tests required for commercial aircraft cabin components. We provide test documentation with material certifications.
Q: What machining tolerances can you achieve?
A: Standard extrusions meet ASTM B107 tolerances. For high-precision CNC requirements, we offer precision grinding to achieve ±0.02mm dimensional accuracy. Tighter tolerances are available for critical applications.
Q: Is there ignition risk during high-speed machining?
A: When following industry-standard safety protocols, ignition risk is virtually eliminated. Use proper tool geometry with sharp edges, maintain appropriate cutting speeds, and apply mineral oil-based coolants. We provide detailed machining parameter recommendations with every order.
Q: How does corrosion resistance compare to aluminum in marine or humid environments?
A: Untreated magnesium requires protective measures in corrosive environments. However, modern surface treatments (anodizing, conversion coatings, PEO) provide excellent corrosion protection comparable to treated aluminum. We help specify appropriate treatments for your operating environment.
Q: Can you supply material certificates for aerospace quality requirements?
A: Yes. Every shipment includes complete material traceability documentation: COA, COC, chemical analysis reports, mechanical test results, and heat treatment records. Our CNAS-accredited lab ensures all certifications meet aerospace audit standards.
