What is ZK60?

ZK60 is a high strength heat treatable magnesium alloy belonging to the Mg-Zn-Zr series, which is mainly used in applications requiring light weight, high strength and good heat resistance.

ZK60 Chemical composition:

Zn (Zinc) : 4.8-6.2%

Zr (Zirconium) : 0.45-0.9%

Mg (magnesium) : allowance

Impurity content: such as Fe, Cu, etc., are strictly limited (usually below 0.01%).

Performance characteristics:

High specific strength: ZK60 has high strength and stiffness among similar magnesium alloys.

Good heat treatment performance: Through T5, T6 heat treatment, can further improve its mechanical properties.

Corrosion resistance: Compared with the AZ series, the ZK60 has relatively poor corrosion resistance, so surface treatment is often required.

Good processing performance: suitable for forging, extrusion and other deformation processing technology.

Mechanical properties (typical data, T5/T6 processing) :

Tensile strength: about 290-340 MPa

Yield strength: about 220-280 MPa

Elongation: 6-12%

Density: about 1.83 g/cm3

Application field:

Aerospace: Lightweight structural components, such as fuselage frames, landing gear components, etc.

Automotive industry: high-performance wheels, drivetrain components.

Military field: Used for high-performance weapon parts and lightweight structures.

Sports equipment: such as bicycle frames, tennis rackets and other high-end products.

Problem and solution:

Is magnesium alloy better than aluminum?

Magnesium alloy is lightweight and environmentally friendly.

What is the strongest magnesium alloy?

ZK60 WE43 WE54 VW63 and so on.

Does magnesium alloy tarnish?

Yes, it needs a surface treatment to keep it bright.
