3. Material Forms, Processing & Technical Specifications
Aikerly provides a comprehensive ecosystem for AZ31B implementation, ensuring that the material is not only delivered in the correct form but also processed under optimal engineering conditions.
I. Available Delivery Forms
I. Available Delivery Forms
Beyond our signature High-Density Round Ingots (Billets), we offer a full range of standardized and customized material forms:
Extrusions: Hot-extruded rods and customized profiles (precision-engineered).
Flat Products: Hot-rolled/Cold-rolled thin plates and strips.
Consumables: High-purity welding wires and electrodes.
Specialty Forms: Alloy powders, spherical particles, and complex forgings.
Applications: Specifically optimized for medium-load structural components and complex-shaped die forgings.
II. Precision Machining & Safety Protocol
II. Precision Machining & Safety Protocol
While AZ31B offers exceptional machinability, its high-speed processing requires strict adherence to magnesium-specific safety standards:
Verdict: Excellent chip formation and surface finish.
Risk Mitigation: To prevent the combustion of fine magnesium powder, continuous use of compatible cutting fluids and high-volume ventilation is mandatory.
Operator Safety: Mechanics must utilize spark-resistant tools and appropriate PPE, maintaining active monitoring of chip accumulation.
III. Advanced Fabrication Techniques
III. Advanced Fabrication Techniques
Forming: Optimal plastic deformation is achieved via preheating to approximately 260°C (500°F).
Welding Integrity: Exceptional weldability via Gas Shielded Arc (GMAW/GTAW). We recommend Gas Tungsten Arc Welding for high-precision joints requiring maximum structural density.
Heat Treatment (Annealing):
Stress Relief: 149°C (300°F) for 30-60 minutes, followed by air cooling.
Full Anneal: 344°C (650°F) with slow furnace cooling.
Atmosphere Control: Furnaces must maintain a neutral or protective gas atmosphere to ensure material purity and prevent oxidation.
IV. Certified Surface Protection
IV. Certified Surface Protection
To extend the service life of AZ31B in aggressive environments, Aikerly supports a wide array of coating technologies:
Primary Coatings: Chromizing, Anodizing, Electroplating, and Electronic Coating (E-coat).
Advanced Protection: Plasma Electrolytic Oxidation (PEO/MAO).
Expert Verdict: We highly recommend PEO for components exposed to high-salinity or high-wear environments to ensure long-term dimensional and chemical stability.
