ZK60A  

Why Choose ZK60A Magnesium Alloy

As a China-based manufacturer and exporter specializing in engineering-grade magnesium alloys, we supply ZK60A products that meet international aerospace and industrial standards for global customers.

Compared with conventional magnesium alloys, ZK60A delivers superior structural strength and reliability, making it especially suitable for strength-critical and fatigue-sensitive applications.

Key Performance Advantages:

• Exceptional specific strength among wrought magnesium alloys

• Significantly improved fatigue life compared with AZ-series alloys

• Better corrosion resistance than standard Mg–Zn alloys

• Well suited for aerospace-grade extrusions and forgings

• Proven performance in aerospace and military programs

ZK60A enables aggressive weight reduction without compromising structural integrity, making it an ideal material for advanced lightweight design.

Processing and Fabrication Characteristics

Forming and Bending

ZK60A can be hot formed after preheating to approximately 260 °C (500 °F). Under controlled conditions, minimum bend radii of approximately 2× material thickness can typically be achieved, depending on section geometry and forming rate.

This makes the alloy suitable for aerospace brackets, frames, and precision-formed structural components.

Welding Behavior

• Recommended method: Resistance welding

• Fusion welding: Challenging due to high zinc content, which increases the risk of hot cracking. Fusion welding is only recommended when specialized filler materials and tightly controlled procedures are employed.

For load-bearing or fatigue-critical structures, mechanical fastening or qualified welding processes are generally preferred.

Heat Treatment Conditions

• ZK60A-T5 is the most common commercial temper

• ZK60A-T6 provides higher strength but typically requires customized heat treatment procedures

For aerospace and defense programs, we offer tailored heat treatment schedules to achieve specific mechanical property targets.

Hot Working Temperature Range

ZK60A is suitable for extrusion, forging, and rolling at temperatures around 260 °C (500 °F). Processing parameters should be optimized based on section thickness, deformation rate, and final performance requirements to ensure refined grain structure and maximized fatigue performance.

Typical Applications

Aerospace and Defense

Used in UAV airframes, rotor components, satellite structures, and missile hardware. ZK60A’s high strength and fatigue resistance meet stringent reliability requirements under extreme operating conditions.

Automotive and Motorsports

Applied in transmission housings, suspension brackets, and engine mounts for racing and high-performance vehicles. Due to corrosion protection requirements, ZK60A is typically reserved for premium or competition-focused platforms.
