Aluminium 1200 | 1200 Aluminum Plate

Introduction of Aluminium 1200:

Aluminium 1200 is industrial pure aluminum, with high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but low strength, heat treatment can not be strengthened, poor machinability; gas welding, hydrogen atom welding and contact welding, not easy to braze; Easy to withstand various pressure processing and extension and bending.

Advantages of Aluminium 1200:

Low density and enhanced

Pure aluminum has a density close to 2700 kg/m3, which is about 35% of the density of iron. Pure aluminum can double its strength by cold working. Moreover, it can be alloyed by adding elements such as magnesium, zinc, copper, manganese, silicon, lithium, and antimony, and further strengthened by heat treatment, and its specific strength is comparable to that of high-quality alloy steel.

Easy processing

Aluminium 1200 can be cast by any of the casting methods. The plasticity of aluminum is good, it can be rolled into thin plates and Aluminum foils; drawn into pipes and filaments; extruded into various civil profiles; can be machined by milling, milling, boring and planing at the speed that most machine tools can achieve.

Corrosion resistant and conductive and thermally conductive

The surface of aluminum and its alloys tends to form a dense, strong Al2O3 protective film. This protective film will be destroyed only by the intense action of halogen ions or alkali ions. Therefore, aluminum has a good resistance to corrosion and water corrosion in the atmosphere, including industrial atmospheres and marine vapors. It can resist the corrosion of most acids and organic substances, and it can resist the corrosion of weak alkali solution by using corrosion inhibitor. It can improve the corrosion resistance of aluminum alloy by protective measures. The electrical and thermal conductivity of aluminum is not less than silver, copper and gold.

No low temperature brittleness

Aluminum is below zero degrees Celsius, and as the temperature decreases, the strength and plasticity will not decrease, but will increase.

Beautiful and reflective

The polished surface of aluminum has a reflectance of more than 80% for white light, and the higher the purity, the higher the reflectance. At the same time, aluminum has good reflection properties for infrared rays, ultraviolet rays, electromagnetic waves, heat radiation, and the like. Aluminum and its alloys have a silver-white luster due to their strong reflective properties. After machining, it can reach a high degree of finish and brightness. Through anodizing and coloring, colorful, dazzling aluminum products can be obtained.
