Contribution presents results of study tribological characteristics Fe-Zn coated steel sheets. Experimental research was done using coatings with different alloying – under alloyed, optimal and slightly pre alloyed. The optimally alloyed the prealloyed ones were annealed in order to reach level. Alloying level evaluated by phase composition % Fe coating. Tribological properties such as surface microgeometry, abrasion, friction coefficient analysed from view formability. strip drawn test used for verification strip-drawn numerical simulation. Based on simulation results, contact pressure drawing die radius observed.
