What is the basic knowledge of aluminum profile?

The aluminum profile titanium plating process used the coating technology. It is a step of adding pre-plating and electroplating processes on the basis of the conventional aluminum extrusion process. The aluminum profile is to chemically treat the activated plated parts in an aqueous solution of salt and hydrochloric acid.
The bath composition of the electroplating process includes nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brightener. The process has the advantages of simplicity, practicability and good effect. The aluminum products made by aluminum section manufacturer obtained by the process has a film hardness of HV ≈ 1500, and is 150 times more wearable than 22K gold under the same conditions, and they can be processed into various forms of aluminum profile in gold, color and black and other bright colors.
Corrosion resistance
The aluminum profile has a density of only 2.7 g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83 g/cm3, 8.93 g/cm3, respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including air, water (or brine), petrochemicals, and many chemical systems.
Conductivity
Aluminum profiles are often chosen for their excellent electrical conductivity. On the basis of equal weight, the electrical conductivity of aluminum is nearly twice that of copper.
Thermal conductivity rate
The thermal conductivity of structural aluminum is about 50-60% of that of copper, which is advantageous for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils and cylinder heads and radiators for automobiles by aluminum profile manufacturers.
Non-ferromagnetic
Aluminum profile extrusions are non-ferromagnetic, which is an important feature for the electrical and electronics industries. Aluminum profile are not self-ignitable, which is important for applications involving handling or contact with flammable and explosive materials.
Machinability
The machinability of aluminum profile is excellent. In various deformed aluminum alloys and cast aluminum alloys, and in various states after the production of these alloys, the machining characteristics vary considerably, which requires special machine tools or techniques.
Formability
The specific tensile strength, yield strength, ductility, and corresponding work hardening rate govern the variation in allowable deformation.
Recyclability
Aluminum extruded products are extremely recyclable, and the properties of recycled aluminum are almost indistinguishable from that of primary aluminum.
