Magnesium Alloy Rectangular Bar: Precision-Engineered Lightweight Solutions
When you're searching for a reliable source of Magnesium alloy rectangular bar, you need more than just material—you need engineering consistency. Shaanxi Hagrien delivers enterprise-grade rectangular bars with extrusion diameters up to Ø300 mm, strict dimensional tolerances (h9-h11), and full batch traceability. Our closed-loop manufacturing controls everything from alloy melting to final inspection, ensuring uniform microstructure and repeatable mechanical properties. With lead times of 2–4 weeks for standard sizes and 4–8 weeks for custom profiles, we support both prototype validation and volume production. Every shipment includes COA/COC documentation, CNAS-accredited test reports, and compliance with ASTM B107/B107M standards.

What Makes Our Rectangular Bars Different?
Engineered for Real-World Performance
You do not fair purchase bars—you contribute in downstream victory. Our rectangular profiles adjust three basic variables: machinability, auxiliary judgment, and weight diminishment. Each bunch experiences ICP-OES chemical examination and ultrasonic testing to kill inside absconds some time recently it comes to your facility.
Size Consistency You Can Measure
Dimensional variety murders productivity. Our expulsion handle keeps up tight resistances over the whole length, decreasing your scrap rates and setup time. Whether you require 20 mm × 40 mm cross-sections or custom geometries, you'll get bars with uniform grain structure and negligible surface oxidation.
From Test to Scale Without Surprises
We bridge the hole between model and generation. Our designing group makes a difference you select the right amalgam review (AZ31B, AZ61, AZ80, ZK60) based on your application requirements—temperature introduction, erosion environment, and mechanical loads. At that point we keep up the same prepare parameters when you scale to volume orders.

Why Rectangular Bars Matter in Your Industry?
Aerospace & Defense Applications
Every gram counts when you're designing aircraft components or satellite frames. Our Magnesium alloy rectangular bars deliver 33% weight savings versus aluminum and 75% versus steel—without sacrificing structural performance. You gain fuel efficiency and increased payload capacity while meeting strict dimensional requirements.
Automotive Powertrain Solutions
Engine-adjacent components confront warm cycling and vibration. Rectangular bars offer prevalent damping capacity compared to aluminum or steel, amplifying component life in gearbox lodgings, brackets, and chassis underpins. The tall warm conductivity makes a difference oversee warm in electric vehicle battery enclosures.
Industrial Mechanization & Robotics
High-speed apparatus requests moo inactivity. Rectangular profiles diminish responding mass in mechanical arms and actuator outlines, permitting quicker cycle times without over-burdening engines. Your hardware runs cooler and keeps going longer.
Electronics Enclosures
EMI/RFI protecting requires conductivity and weight productivity. Magnesium rectangular bars machine effortlessly into complex walled in area geometries whereas giving common electromagnetic security for touchy hardware.
