What type of aluminum alloy 6061?

2019-05-10 13:19:11 yx8 48


Belonging to 6061 genera and strengthens the alloy heat treatment, with good formability and weldability, processability, with moderate intensity at the same time, can still maintain a good operational after annealing.

6061 alloy magnesium and silicon are the main alloy elements, and formed Mg2Si phase. If contains a certain amount of manganese and chromium, can counteract the bad effect of iron; Sometimes add a small amount of copper or zinc, in order to improve the strength of the alloy, and don't make it have a significantly lower resistance to corrosion; Conductive material with a small amount of copper, in order to offset the bad influence of titanium and iron for electrical conductivity; Zirconium or titanium can refine grain and controlling recrystallization organization; In order to improve cutting performance, can be added to the lead and bismuth. In Mg2Si solid soluble in aluminum alloy artificial aging hardening function.

6061 - T651 is the main alloy, alloy 6061 is the pre-draft heat treatment process of high quality aluminum alloy products, its strength is not compared with 2 or 7 XXX XXX department system, but its more magnesium, silicon alloy properties, has the excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and processing after deformation, dense material without defects and easy polishing, coloring film easily, good features such as oxidation excellent results.

Typical application

Board tape applications are widely used in decoration, packaging, construction, transportation, electronic, aviation, spaceflight, weapons and so on all walks of life.

Aerospace aluminum used in making aircraft skin, body frame, truss, rotor, propeller, fuel tank, wall plate and the landing gear strut, and the rockets forging ring, spacecraft wall plate, etc.

With aluminum used in automobile transportation, subway, high-speed passenger vehicles, railway passenger car body structure of the material, car doors and Windows, shelves, automobile engine parts, air conditioner, radiator, panels, wheel hub and ship material.

Packing aluminum aluminum cans can all materials mainly in the form of sheet and foil as packaging materials, metal cans, lid, bottles, barrels, foil packing. Widely used in beverage, food, cosmetics, medicine, cigarette, industrial products such as packaging.

Made of aluminum is mainly used for printing PS version, aluminium base PS version is a kind of new materials, printing for automated plate making and printing.

Architectural decorative aluminum alloy because of its good corrosion resistance, sufficient strength, excellent process performance and welding performance, mainly is widely used in building architecture, such as doors and Windows, ceiling, decorative surface. Such as all kinds of building doors and Windows, curtain wall with aluminum, aluminum curtain wall plate, pressure plate, decorative pattern plate, colour coating sheets, etc.

Electronic appliances with aluminum is mainly used for various bus, wiring, conductor, hardware (C type clamp, C type clamp equipment, energy-saving clamp torque, torque lock connection device, ample clamp, wei ma clamp, torsion wire clip (terminal, connection tube), meter box clamp), electrical components, refrigerator, air conditioning, cable, etc. Specification: round rod, square rod
