Product Description

Product Overview

Magnesium alloy rods and bars in grades AZ31B, AZ61A, and AZ91D are engineered for anti-corrosion cathodic protection applications. These high-performance alloys combine low density with excellent machinability, making them a reliable choice for demanding industrial environments.

Key Features

High work-hardening rate. Compared with aluminum alloy and mild steel, magnesium alloys exhibit superior resistance to denting when objects collide, making them ideal for small home appliances, mobile phones, and digital cameras.
Excellent machinability. Low cutting resistance reduces power consumption, shortens processing time, and extends tool life.
High recycling value. Regenerating magnesium alloy requires only about 5% of the energy used in initial material manufacturing — a significant advantage for meeting environmental regulations.
Low specific heat. Magnesium alloys heat and cool quickly and offer excellent dimensional stability, with a change of only 6×10⁻⁶ over 150–100 hours of heating.

Product Advantages

Lightweight. Magnesium is the lightest structural metal material in the world.
High specific strength. Magnesium alloy offers high strength-to-weight ratio and reliable bearing capacity.
Small modulus of elasticity. Provides better strength and anti-seismic performance with minimal distortion.
Good anti-electromagnetic interference and shielding.
Non-polluting and fully recyclable.
Dimensionally stable and easy to process.
