Summary:Mechanical properties and structure of a thin aluminum coating were investigated. Experimental methods of measuring yield stress, strength and fracture strain of ultrathin coatings were developed. Yield stress, strength and fracture strain of aluminum increase with decrease in the coating thickness. The increase of yield stress and strength was explained by reduction of the crystal size and by strain-hardening of metal. •We describe an estimating method of thin coatings strength-strain properties.•We perform the study of characteristics of coating deposited on polymer substrate.•We estimated mechanical properties of Alumina layers deposited onto the polymer.•Aluminum is amorphous if the coating thickness is lower than 5–10nm.
