1.Company Introduction

2.Features:

1.Corrosion resistance

Under most environmental conditions, aluminum can display excellent corrosion resistance, including air, water (or brine), petrochemistry and many chemical systems.

2.Conductivity

On the basis of equal weight, the conductivity of aluminum is nearly two times that of copper.

3.Thermal conductivity rate

The thermal conductivity of the aluminum alloy is about 50-60% of the copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and the cylinder head and radiator of the car.

4.Nonferromagnetism

Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical industry and the electronics industry. Aluminum profiles are not self ignition, which is important for the application of loading and unloading or contact with flammable and explosive materials.

5.Machinability

The machinability of aluminum profiles is excellent. In all kinds of deformed aluminum alloys and cast aluminum alloys, and in the various states after these alloys are produced, the change of machining characteristics is quite large, which requires special machine tools or technology.

6.Formability

The specific tensile strength, yield strength, ductility and the corresponding work hardening rate govern the variation of allowable deformation.

7.Recovery

Aluminum has very high recyclability, and the properties of recycled aluminum are almost the same as that of native aluminum.

3.Introduction

    The principle of the heat insulation broken bridge aluminum alloy is to penetrate the heat insulation strip in the middle of the aluminum profile, and break the aluminum profile to form a broken bridge, thus effectively preventing the heat conduction. The thermal conductivity of insulated aluminum alloy doors and windows is 40 to 70% less than that of non heat insulated aluminum alloy doors and windows.

    There are two main ways of producing heat insulation sections. One is to use insulation material and aluminum profiles to form a "heat insulation bridge" through mechanical opening, wearing and rolling. The other is to pour heat insulation material into the heat insulation cavity of the aluminum alloy section and remove the broken bridge metal after curing. And other processes to form "insulated bridge", known as "cast" heat insulation profiles. The inside and outside sides of the thermal insulation profiles can be profiles with different sections, or different color profiles with different surface treatments. However, due to the geographical and climatic effects, the gap between thermal insulation materials and the linear expansion coefficient of aluminum profiles is very large. In the heat expansion and contraction, there is greater stress and gap between the two. At the same time, the heat insulation material and the aluminum profile are combined into one. In the windows and curtain wall structure, the same is the same as the aluminum material. Therefore, the insulation material must also have the tensile strength, bending strength, expansion coefficient and modulus of elasticity that are close to the aluminum alloy profiles, otherwise the heat insulation bridge will be broken and destroyed. Therefore, the selection of heat insulation materials is very important.
