Beschreibung
Zusammenfassung:	The invention discloses an acid etching treatment solution and a treatment method for aluminum and aluminum alloy products. The acid etching treatment solution has density of between 1.60 and 1.70kg/L; and 100L of acid etching treatment solution comprises the following raw materials: 130 to 150kg of phosphoric acid with mass fraction of between 80 percent and 90 percent, 8 to 12kg of nitric acid with mass fraction of between 60 percent and 70 percent, 1 to 3kg of Al, 2 to 4kg of stabilizer and 10 to 20L of water. The acid etching treatment solution is acidic and does not react with stainless steel (SUS-316L), titanium and alloy, so that the acid etching treatment solution can be applied to an automatic production line, comprises simple components, and is easy to detect and analyze and convenient to control.
