1050 Precision Aluminum Tube, is a kind of aluminum alloy profile with the advantages of good ductility, strong hardness, smooth surface, corrosion resistance, oxidation resistance, etc. 1060, 1070, 1080 are all belong to the high-precision duraluminum, of which 1060 is pure aluminum material, 1070 and 1080 are added a certain amount of manganese, silicon alloy, so the hardness is higher, the strength is better, but the toughness has been reduced.
1, 1050-1075 series: belongs to the high-precision hard aluminum alloy, its mechanical properties are much higher than the soft high-pressure cast steel, forging of ordinary industrial aluminum alloy. After quenching in the extrusion molding process, its yield strength can exceed 1000MPa, tensile strength of 1500MPa or more.
2, 1100-1150: for the super-hard high-strength deformed aluminum alloy. It is in the 1XXX system (such as 1100) on the basis of artificial addition of a small amount of carbon, boron, sulfur, nitrogen and trace elements (such as lead or zinc), so that the solid solution strengthening, and eliminate the tendency of grain growth. Therefore, its room temperature plasticity is low and tensile strength, yield limit is high.
3, 1115-1200: for the medium strength of the full tensile hardening aluminum alloy, in the recrystallization temperature range, has good machinability. Heat treatment at 840-853°C is preferred.
4,1210-1245:1200 series alloy contains martensitic organization that can form dense oxide film. Due to the existence of work hardening phenomenon. Therefore, it is used for the complex force, high requirements of the parts is quite suitable. The higher the silicon content, the greater the degree of work hardening. White spots are easily produced when cooling in air. It works well when sufficient lubricant is added. In 1803 ~ 1820 ° C aging, can get the highest hardness of the martensitic organization. Particularly effective for the reinforcement of impregnated fabrics consisting of nitrocellulose, nitrocellulose or viscose fibers. Should not be used less than 1763 ° C temperature long-term storage.
5, 1305-1350: 1300 series is a more commonly used models, with good wear resistance. Ferritic stainless steel because of the addition of chromium to reduce the resistivity, there is also a great improvement in the oxidation resistance, but the price is relatively high.
6, 1400-1435: 1400 series belongs to the cold rolled conventional products, the current application of more widely used products, mainly characterized by low density, corrosion resistance, not easy to rust, easy to polish and grind; drawbacks are poor welding performance, post-weld plasticity and corrosion resistance is poor.
7, 1505-1605: 1555 --> 1655, is a precipitation hardening stainless steel, the so-called stainless steel, in fact, part of the copper, part of the zinc and manganese alloy.
