>FAQ: Aluminum Machining
6061 vs. 7075: Which aluminum alloy is best for my project?
Choose 6061-T6 for general-purpose applications, welding, and superior anodizing results. Opt for 7075-T6 for aerospace or high-stress components requiring maximum strength-to-weight ratios and fatigue resistance.
How do you prevent warpage and deformation in aluminum?
We utilize a "Stress-Free" process: roughing, followed by stress-relief annealing, and final precision finishing. This sequence releases internal material tension, ensuring your thin-walled parts remain flat and within tolerance.
Can you guarantee a scratch-free finish for cosmetic parts?
Yes. Beyond high-speed mirror milling to eliminate tool marks, we use custom-designed trays and specialized handling protocols to prevent metal-to-metal contact, ensuring a flawless surface for decorative anodizing.
What tolerances can ProtoBatch achieve for aluminum milling?
Our standard precision tolerance is ±0.01mm. For critical applications, we utilize CMM verification and digital thread gages to ensure every bore, flange, and thread meets your exact aerospace or medical specifications.
What anodizing options are available for CNC aluminum?
We provide Type II decorative anodizing in multiple colors (Black, Blue, Red, Gold), Type III Hardcoat for wear resistance, and Chromate Conversion (Alodine) for conductive, corrosion-resistant coatings.
How do you manage thin-wall geometries and heat dissipation?
We specialize in CNC machining fins and walls as thin as 0.5mm by optimizing chip evacuation and using high-pressure coolant to prevent heat-induced distortion and tool-clogging (Built-up Edge).
