1060 aluminum, with an aluminum content of 99.6%, is also known as pure aluminum. It is the most commonly used series. The production process is relatively simple, the technology is relatively mature, and the price has a huge advantage over alloy aluminum. Can 1070 aluminum welding wire be used for pure aluminum 1060 welding? The answer is yes, let's understand the characteristics of pure aluminum:
●Low density
The density of pure aluminum is close to 2700 kg/m3, which is about 35% of the density of iron.
●Can be strengthened
Although the strength of pure aluminum is not high, it can be more than doubled by cold working. Moreover, it can be alloyed by adding elements such as magnesium, zinc, copper, manganese, silicon, lithium, resistance, etc., and then further strengthened by heat treatment, and its specific strength is comparable to that of high-quality alloy steel.
●Easy to process
Aluminum can be cast by any casting method. Aluminum has good plasticity and can be rolled into thin plates and foils; drawn into tubes and filaments; extruded into various civil profiles; it can be machined, milled, bored, and planed at the maximum speed that most machine tools can reach.
●Preservative
The surface of aluminum and its alloys is easy to form a dense and strong protective film. This protective film will only be destroyed under the intense action of halogen ions or alkali ions. Therefore, aluminum has good resistance to atmospheric (including industrial atmosphere and marine atmosphere) corrosion and water corrosion. It can resist the corrosion of most acids and organics, adopts corrosion inhibitors, can resist weak alkali corrosion; adopts protective measures, can improve the corrosion resistance of aluminum alloy.
●No low temperature brittleness
Aluminum is below zero degrees Celsius. As the temperature decreases, the strength and plasticity will not decrease, but will increase.
●Good electrical and thermal conductivity
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold. At room temperature, the equal volume conductivity of electrical aluminum can reach 62% IACS. If calculated according to the conductivity per unit mass, its conductivity is twice that of copper.
●Highly reflective
The reflectivity of the polished aluminum surface to white light is more than 80%. The higher the purity, the higher the reflectivity. At the same time, aluminum has good reflection properties for infrared, ultraviolet, electromagnetic waves, and heat radiation.
●Non-magnetic, no sparks from impact
This is very valuable for some special purposes, such as instrument materials, shielding materials for electrical equipment, and production equipment for flammable and explosive materials.
Sound absorption is beneficial to interior decoration, and it can also be formulated into damping alloys.
●Resistance to nuclear radiation
For high-energy neutrons, aluminum has the same degree of neutron absorption cross-section as other metals. For neutrons in the low-energy range, its absorption cross-section is small, second only to metals such as plating, magnesium, and aluminum. The biggest advantage of aluminum's resistance to nuclear radiation is that the induced radiant energy generated by irradiation decays quickly.
●Beautiful
Aluminum and aluminum alloys have a silver-white luster on the surface due to their strong reflective ability. After machining, it can achieve a high degree of finish and brightness. If anodized and colored, not only can the corrosion resistance be improved, but also colorful and dazzling products can be obtained. Aluminum is also an excellent substrate for the production of painted materials.
