The titanium gold plating process for aluminum profiles is a coating technology. It is based on the conventional titanium plating process and adds pre-plating and electroplating process steps. The pre-plating process is to place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment. The plating solution components of the electroplating process include nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brightener. This process has the advantages of simplicity, practicality, and good effects. The film layer of the titanium-gold aluminum profile is The hardness HV≈1500 is 150 times more wear-resistant than 22K gold plating under the same conditions. It can be processed into various series of gold, color, black and other bright aluminum profile products. my country is the world's largest aluminum profile production base and consumer market.
