Magnesium az31b price

Magnesium AZ31B is a wrought magnesium base alloy with good room-temperature strength and corrosion resistance. When sourcing, you must verify the chemical composition, specifically ensuring Aluminum (2.5-3.5%) and Zinc (0.6-1.4%) levels meet ASTM B90 standards. Additionally, check the temper condition (e.g., H24, H26, or O temper) as this significantly impacts the material's tensile strength and elongation properties.

The price varies significantly based on whether you require sheets, plates, bars, or tooling blocks. For aerospace and automotive components, high precision and surface flatness are critical, often requiring CNC-machined finishes. For vibration damping applications or electronic housings, the focus shifts to lightweight properties and electromagnetic shielding effectiveness. Always specify the dimensional tolerances required, as tighter tolerances will increase the unit price.

Suppliers should provide a Material Test Report (MTR) or a Mill Test Certificate (MTC) according to EN 10204 3.1. Ensure the product complies with RoHS and REACH regulations, especially if exporting to the EU. For high-end manufacturing, look for suppliers with ISO 9001 or AS9100 (aerospace) certifications to ensure consistent metallurgical quality and traceability.

To achieve the best price, consider bulk purchasing; orders exceeding 500kg to 1 ton usually trigger significant volume discounts. Since magnesium prices fluctuate with the global metal market (LME), it is wise to negotiate long-term supply contracts to hedge against price volatility. Additionally, sourcing from verified manufacturers on Made-in-China.com can reduce middleman markups and provide access to factory-direct pricing.

Magnesium in certain forms (like powder or thin turnings) is classified as a Class 4.1 Flammable Solid. While solid plates and bars are more stable, they still require specialized packaging to prevent oxidation and moisture damage. Ensure the supplier uses vacuum sealing or anti-rust oil and provides the correct Material Safety Data Sheet (MSDS) for customs clearance to avoid shipment seizures.

Always use Secured Trading Services provided by platforms like Made-in-China.com to protect your payment until the goods are verified. Negotiate a payment term such as 30% deposit and 70% against the Bill of Lading (B/L). Request a pre-shipment inspection by a third party (like SGS or Intertek) to verify the alloy grade and quantity before the final balance is paid.

For large volumes of AZ31B, Sea Freight (FCL or LCL) is the most economical method. Ensure the supplier is familiar with Incoterms 2020 (FOB or CIF are standard). For urgent prototypes, Air Freight is possible but expensive due to weight. Always confirm if your country imposes anti-dumping duties on magnesium products from China to accurately calculate your Total Cost of Ownership (TCO).
