FAQ
Q: Is AZ31B safe to machine given magnesium's flammability?
A: Yes, but with strict rules. You must never dry-machine it. Use sharp tools, high feed rates, and a dedicated water-based or oil-based coolant to suppress sparks. Keep the work area completely clear of fine magnesium dust to eliminate fire hazards.
Q: Does AZ31B rust or corrode easily compared to aluminum?
A: It corrodes more easily than aluminum. AZ31B is highly susceptible to galvanic corrosion and saltwater. If your part will be exposed to the elements, you must apply a surface treatment like micro-arc oxidation (MAO), powder coating, or anodizing.
Q: What is the advantage of AZ31B over aluminum 6061?
A: AZ31B is about 35% lighter than aluminum, offering superior specific strength. It also has much better vibration damping and impact resistance, making it the preferred material for aerospace brackets, portable electronics, and high-end drone frames.
Q: Do you supply AZ31B in forged or extruded bar form?
A: We primarily supply extruded round bars and forged blocks from our production base. We also have die-casting capabilities (up to 2500 tons) if you need finished or semi-finished castings rather than raw bars.
Q: Can you provide samples for a prototype?
A: Yes, we can cut short trial bars from stock. Since magnesium requires careful packing, you will only bear the freight and material cost. Sample costs can be deducted against a bulk order exceeding 1 ton within 90 days.
