Method for distinguishing aluminum alloy and titan

  • Detail

Here is a simple comparison method:

(1) specific hardness, one is aluminum and the other is titanium alloy, as long as the two materials are drawn with each other. The scratched piece is aluminum. Because titanium is harder than aluminum

(2) compared with acid resistance, aluminum reacts immediately with acid, and titanium has good acid resistance

(3) specific strength, it is very labor-saving to destroy aluminum with pliers and scissors, and titanium is very laborious

(4) compare the color. Draw a few strokes on a piece of white paper. Aluminum immediately leaves black scratches. Titanium can't see the scratches
