Aluminum alloy door and window extrusion

In just a few decades, the industry has used advanced technology to promote industry structure adjustment, promoted product renewal, structural optimization, grasped cutting-edge science and technology, and narrowed the gap with the international advanced level. my country's aluminum door and window building curtain wall industry has experienced a glorious development. Aluminum alloy doors and windows are the product of the development of modern new building materials. They have been developed in developed countries such as Germany, the United States, and the United Kingdom as early as the 1930s. Because aluminum alloy profiles are light in material, they can extrude profiles with complex cross-sectional shapes, especially aluminum The beautiful appearance of alloy doors and windows and their excellent building physical properties have made them affirmed by architects.

Aluminum profile features

Aluminum profile corrosion resistance: The density of aluminum profile is only 2.7g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). Under most environmental conditions, including air, water (or salt water), petrochemical and many chemical systems, aluminum can show excellent corrosion resistance.

Aluminum profile conductivity: Aluminum profile is often selected because of its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is close to 1/2 of copper.

Thermal conductivity: The thermal conductivity of aluminum alloy is about 50-60% of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.

Non-ferromagnetic: Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not spontaneously combustible, which is important for applications involving handling or contact with flammable and explosive materials.

Workability: The workability of aluminum profiles is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in the various states these alloys have after being produced, the machining characteristics vary considerably, which requires special machine tools or technology.

Formability: The specific tensile strength, yield strength, ductility and corresponding work hardening rate dominate the change in allowable deformation.

Recyclability: Aluminum is highly recyclable, and the characteristics of recycled aluminum are almost indistinguishable from primary aluminum.

Surface treatment

As aluminum alloy parts may be in a humid working environment or assembled with other parts of different materials, in order to improve and ensure the wear resistance, corrosion resistance and visibility of the parts, magnesium alloy parts must be surface treated. The pretreatment will affect the subsequent spraying. During the manufacturing process, the parts may be contaminated by some contaminants such as grease, oxides, lubricants and foreign matter, and these residual impurities must be removed.
Generally, the pretreatment of aluminum alloy parts can be divided into four categories: mechanical cleaning, solvent cleaning, lye cleaning, and acid cleaning. These methods can be used alone or in combination. Pay attention to the supply of abrasive powder and water during the polishing process, and the polishing should be very bright!
