Industrial aluminum profiles are also called: industrial aluminum extrusions, industrial aluminum alloy profiles, industrial aluminum profiles are an alloy material with aluminum as the main component, aluminum rods are hot-melted and extruded to obtain aluminum materials with different cross-sectional shapes, but The proportion of the added alloy is different, and the mechanical properties and application fields of the produced industrial aluminum profiles are also different. Fields of application Generally speaking, industrial aluminum profiles refer to all aluminum profiles except for building doors and windows, curtain walls, interior and exterior decoration, and aluminum profiles for building structures.

Features of aluminum profiles

1. Non-ferromagnetic

Aluminum profiles are non-ferromagnetic, which is an important property for the electrical and electronics industries. Aluminum profiles are not self-igniting, which is important for applications involving handling or contact with flammable and explosive materials.

2. Machinability

The machinability of aluminum profiles is excellent. In various wrought aluminum alloys and cast aluminum alloys, and in the various states these alloys have after they are produced, the machining characteristics vary considerably, requiring special machine tools or techniques.

3. Formability

Aluminum has strong tensile strength, yield strength and plasticity, and has good ductility

4. Recyclability

The chemical properties of aluminum are stable, non-magnetic, and can be recycled repeatedly. The characteristics of recycled aluminum are almost the same as those of primary aluminum, and it is a benign and recyclable metal material.

5. Corrosion resistance

The density of the aluminum profile is only 2.7g/cm3. It has been treated by hot and cold processes. It has strong corrosion resistance, and aluminum can show excellent corrosion resistance.

6, Good thermal and electrical conductivity

Aluminum alloy has good thermal conductivity and electrical conductivity. The electrical conductivity of aluminum is close to 1/2 that of copper, and the thermal conductivity is about 50-60% of copper.

Production Process

Aluminum profiles are process materials that place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment.

1. Melting and casting is the first process of aluminum production, the main process is: batching, melting, casting

2. Extrusion is the means of profile forming. First, design and manufacture the mold according to the cross-section of the profile product, and use the extruder to extrude the heated round cast rod from the mold.

3. Coloring and oxidation: Extruded aluminum alloy profiles have poor surface corrosion resistance, so surface treatment must be carried out through anodic oxidation to increase the corrosion resistance, wear resistance and aesthetic appearance of the aluminum material. The main process is: surface pretreatment, anodic oxidation, sealing

4. Titanium plating process, aluminum profile titanium plating process, including material selection, polishing, chemical degreasing, water rinsing, activation, vacuum titanium plating process steps.
