At first choose type of alloys in the demonstration was in "Alloy on Cu base".
Then select the state, e.g. "Deutschland".
We will search alloy with contents 10 % Ni and 86 % Cu. In column for "Nickel" choose value "10"
from tables, which will display on the right. Similarly enter also contents of copper - "86".
Now you choose degree of accuracy of search. In demonstration was in "medium".
Now you choose degree of accuracy of search. In demonstration was in "medium".On the right down display labels
of alloys with setting chemical composition . After active one’s items, e.g . "2.0877"  on the left will show chemical composition this alloy. Top left you see precision searchings for setting element and circa in the centre is presented
