Aluminum materials. The following mainly uses 6061 aluminum alloy as an example to introduce:
6061 Aluminum Alloy
6061 aluminum alloy is a heat-treatable alloy with good formability, weldability, machinability, and medium strength, and can still maintain good operability after annealing.
6061 aluminum alloy chemical composition (%):
Cu: 0.15~0.4 Mn:0.15 Mg:0.8~1.2Zn: 0.25 Cr: 0.04~0.35 Ti: 0.15 Si:0.4~0.8 Fe: 0.7 Al: balance
Main application: Widely used in various industrial structural parts that require a certain strength and high corrosion resistance, such as manufacturing trucks, tower buildings, ships, trams, and railway vehicles. 6061 aluminum alloy properties:
The ultimate tensile strength of 6061 aluminum alloy is 124MPa, the tensile yield strength is 5.2MPa, the elongation rate is 25.0%, the modulus of elasticity is 68.9 GPa, and the bending ultimate strength is 28MPa.
6061 is commonly used in aerospace fixtures, trucks, tower structures, pipelines, ships, aircraft, aerospace, defense and other architectural applications requiring strength, weldability and corrosion resistance.
6061 aluminum alloy has the following advantages: 1. High-strength heat-treatable alloy. 2. Good mechanical properties. 3. Good usability. 4. Easy to process, good wear resistance. 5. Good corrosion resistance and oxidation resistance
6061 aluminum alloy is commonly used in aerospace fixtures, trucks, tower buildings, pipelines, ships, aircraft, aviation, defense and other architectural applications that require strength, weldability and corrosion resistance field. Such as: aircraft parts, gears and shafts, fuse parts, instrument shafts and gears, safety parts jump valve parts, turbines, keys, etc.
It is an A-Mg-Si alloy with medium strength, good plasticity and excellent corrosion resistance. In particular, there is no tendency of stress corrosion cracking, its weldability is excellent, corrosion resistance and cold workability are good, it is a kind of Wide range of use. Very promising alloy. It can be anodized and colored, and can also be painted with enamel, which is suitable for building decoration materials. It contains a small amount of Cu, so its strength is higher than that of 6063, but it is sensitive to quenching.
3, Characteristics and Improvement Trends of Rail Sections:
It is also higher than 6063. Air quenching cannot be achieved after extrusion, and it needs to be re-solutionized and quenched to obtain higher strength.
The main alloying elements of 6061 Taiwan gold are magnesium and silicon, and form Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; sometimes a small amount of copper or zinc is added to improve the hardness of the alloy.
Strength without significantly reducing its corrosion resistance; there is a small amount of copper in the conductive material to offset the adverse effects of titanium and iron on conductivity; aluminum or titanium can refine the grain and control the recrystallization structure;
In order to improve machinability, lead and bismuth can be added. The solid solution of Mg2Si in aluminum makes the alloy have the function of artificial aging hardening.
6061-T651 is the main alloy of 6061 alloy. It is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. Although its strength cannot be compared with 2XXX series or 7XXX series, its magnesium and silicon alloys are special.
It has many properties, excellent processing performance, excellent welding characteristics and electroplating properties, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, easy to apply color film,excellent oxidation effect and other excellent features.
4, Rail production flow chart:
Melting → casting → sawing rods → homogenizing aluminum rods → cooling, washing rods → aluminum rods into the warehouse.
