Elektron® 21

Elektron® MAP+21 is a high-performance, gas-atomized, magnesium-alloy powder specifically designed and optimized for additive manufacturing applications.

Elektron® MAP+21 is based on a rare-earth-containing magnesium casting alloy, Elektron® 21 (ASTM: EV31A), a lightweight, high-performance alloy designed for motorsport and aerospace applications, with superior mechanical properties and improved corrosion resistance.

Elektron® MAP+21 powders are available in particle size distributions of 20 to 63 µm and 44 to 160 µm. Custom particle size distributions are also available.
