Aluminium or aluminum is a chemical element with syol Al and atomic nuer 13. It is a silvery-white, soft, nonmagnetic and ductile metal in the boron group. By mass, aluminium comprises about 8% of the Earth''s crust; it is the 3rd most abundant component after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle listed below.

Aluminum dip brazing is a process in which two pieces of metal are joined together with a filler metal when heated to the melting point of the filler metal in the molten chemical salt bath. Dip brazing allows pieces to be joined when there is no access to the joint, because the joining material is drawn into the joint through capillary action.
Aerospace Alloys, Inc. undertook this project to manufacture prototype through production quantities of custom beer tap handles. Because the relative volume of the order was small, we were able to eliminate the associated tooling costs by using abrasive waterjet cutting machines. Using a customer supplied print, we waterjet cut custom architectural metal fabriion beer taps […]

Aluminum forgings are frequently used in industries where weight is a concern, such as aerospace, because of their strength-to-weight ratio, low production cost, low density, and its ability to handle the harsh conditions of space.
2016/7/3· Dye Penetrant Inspection Called DPI, liquid penetrant inspection (LPI), or penetrant testing (PT), this is a low-cost inspection method widely used to loe surface-breaking defects in non-porous materials (metals, plastics, ceramics). LPI is used to detect casting, forging, and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in

Following the invention of the electrochemical method of aluminium production, the scope of aluminium production and appliion began expanding almost exponentially. In the 10 years that followed, from 1890 until 1899, global aluminium production amounted to 28 thousand tonnes.
To that end, nondestructive testing is a critical part of aerospace manufacturing, and neutron imaging is a powerful, albeit underutilized testing method. Using a directed stream of neutron radiation to see through complex materials can ch many flaws and defects that would go completely unnoticed through other means of testing, such as structural weaknesses in 3D-printed components.

Unsurprisingly, since welding is one of the most effective methods of fusing metal, the aerospace industry has plenty of use for it. In fact, aerospace engineers employed welding to make the very first commercial aircraft.Gas welding was once the standard production method – it’s still used now for aircraft repairs – but it has been supplanted by electrical arc welding.
Prevention Methods: Mould should be fully preheat, the granularity of coatings (graphite) shoulds not be too thin, permeability needs to be good. Using tilt pouring way when casting. Raw materials should be stored in ventilated, dry place, and should be preheated
