SEN Alloy Properties

SEN Alloy

Stainless, Environment-friendly, Non-flammable

With the high corrosion resistance flame retardant alloy (SEN alloy) technology owned by the Korea Material Research Institute, the complex addition of Ca and Y and the formation of a dense oxide layer with a multi-layer structure, improved ignition temperature by 150°C compared to commercial Mg, and minimizing or eliminating the use of SF6 gas, a protective gas It is possible to simultaneously improve corrosion resistance and flame retardancy without reducing mechanical properties.

Strengths of Mg Alloy

Lowest Density	High Specific Strength
Lightweight material	Excellent material application scalability

Weaknesses of Commercial Mg alloy

Ignition Hazard	Reduced Corrosion Resistance	Poor Machinability and Castability	Raw material Manufacturing
Limits on application of transport parts	Restrictions on the application of parts	Cost increase	CO2 Emissions Issues

Improved properties of SEN Alloy

Improved Corrosion Resistance	Improved Fame Retardant	Improved Mechanical properties
Expansion of part application	Reduced risk of fire from ignition	Similar and increased compared to commercial Mg

Fire resistance, corrosion resistance and mechanical properties satisfied through the complex addition of calcium (Ca) and yttrium (Y)

Eco-friendly process by suppressing and excluding the use of SF6 gas in the melting/casting process with flame retardancy
