Product Description
Hot Rolled Magnesium Alloy Plate AZ31B - CNC Machining & Stamping Grade
The Hot Rolled AZ31B Magnesium Alloy Plate is engineered for precision CNC machining and metal stamping applications. Featuring an oil-free bright silver surface finish and complete annealing process, this plate delivers exceptional formability, consistent mechanical properties, and a clean surface ready for immediate fabrication.
Key Features
- CNC Process Optimized: Complete annealing treatment ensures uniform grain structure and stress relief, providing superior machinability for CNC milling, turning, and drilling operations with minimized tool wear and excellent chip formation.
- Hot Rolled Quality: Produced through controlled hot rolling process, achieving uniform thickness tolerance and consistent through-thickness mechanical properties ideal for demanding precision fabrication.
- Oil-Free Bright Silver Surface: Clean, degreased surface with bright silver metallic appearance eliminates pre-cleaning requirements before CNC machining or stamping, reducing processing time and ensuring contamination-free finished parts.
- Stamping Ready: Fully annealed microstructure provides excellent ductility and formability for deep drawing, blanking, and progressive die stamping operations without cracking or surface defects.
- Complete Annealing Process: Each plate undergoes full annealing at controlled temperature with gradual cooling, ensuring complete stress relief, uniform hardness, and optimal elongation properties for consistent fabrication results.

Why Choose Our Hot Rolled Magnesium Plates?
Unlike standard magnesium sheets that arrive with rolling oil residue requiring degreasing, our plates feature an oil-free bright silver surface ready for immediate CNC machining or stamping. The complete annealing process—not just stress relief—ensures fully recrystallized grain structure for maximum formability and consistent dimensional stability. With tight thickness tolerance control from hot rolling and a proven supply chain for global customers, our AZ31B plates are the reliable choice for precision manufacturing.
