Metal 3D printing

Additive manufacturing, also called 3D printing, is a process used to create three-dimensional parts from a digital file. It usually involves building up, or solidifying, thin layers of material to create complete parts. The technology is able to produce complex shapes which cannot be produced by 'traditional' techniques such as casting, forging and machining.

Different Types of Aluminum Grades

2021/5/4Cast alloys of aluminum are named using four numbers, with a decimal between the third and fourth digit. The first three numbers indicate the alloy, and the fourth number indicates the form the product is in. Below, in Table 1, is shown the different types of cast

aluminium (US: aluminum)

resists corrosion because of the strong thin layer of aluminium oxide on its surface. This layer can be strengthened further by anodising the aluminium. Anodising essentially involves etching the aluminium with sodium hydroxide solution to remove the existing oxide layer, and then making the aluminium article the anode in an electrolysis of dilute sulphuric acid.

Aluminium Oxide: Properties, Production, and

Aluminium oxide is an inert, odourless, white amorphous material that is used in various industries owing to its exquisite thermal, mechanical, and chemical properties. It is also known as alumina, and exists naturally as corundum or bauxite.

One downside of passivation is that the oxide layer can inhibit electrical conduction. Consequently, stainless steels are not known for good electrical conductivity. Aluminum's high conductivity, along with thermal conductivity three times greater than that of steel, has led to its use in power transmission lines.

Extraction of aluminium from bauxite ore

Top layer consist of molten pure aluminum in which a number of carbon electrodes are suspended. These carbon electrodes act as the cathode. When electric current is passed, the aluminium ions from the middle layer move to the top layer and are discharged at the cathode as pure aluminium.

Aluminum Alloys 101

An aluminum alloy is a chemical composition where other elements are added to pure aluminum in order to enhance its properties, primarily to increase its strength. These other elements include iron, silicon, copper, magnesium, manganese and zinc at levels that combined may make up as much as 15 percent of the alloy by weight.

3D printing of Aluminium alloys: Additive Manufacturing of

2019/12/1Additive Manufacturing (AM) processes are sometimes termed Layered Manufacturing in reference to the nature of the process, where a part is fabricated layer-by-layer from three-dimensional (3D) data. Industry is now benefiting from fabricating geometrically-complex structures using a range of available AM technologies.

How and why alloying elements are added to aluminum

Q: I have been informed that pure aluminum is not usually used for structural applications and that in order to produce aluminum that is of adequate strength for the manufacture of structural components, it is necessary to add other elements to the aluminum.

Chemistry for Kids: Elements

Pure aluminum is a very reactive element and is rarely found on Earth in its free form. Aluminum acts as an excellent conductor of electricity and heat, but is non-magnetic. When it is exposed to the air, a thin layer of aluminum oxide is formed on the surface of the metal.

Why Are Alloys Used Instead of Pure Metals?

2020/3/24Pure metals have a more uniform layer of atoms, which also makes the atom layers more vulnerable to movement. Most pure metals are not used in manufacturing due to their softness when compared to alloys. Some alloys also enhances the properties of the

The 7 categories of Additive Manufacturing

2021/5/4Although media likes to use the term "3D Printing" as a synonym for all Additive Manufacturing processes, there are actually lots of individual processes which vary in their method of layer manufacturing. Individual processes will differ depending on

How aluminium is produced

The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.

Niobium

Niobium belongs to the group of refractory metals. Refractory metals are metals that have a higher melting point than platinum (1,772 C).In refractory metals, the energy binding the individual atoms together is particularly high. Refractory metals have a high melting point coupled with a low vapor pressure, high modulus of elasticity and high thermal stability.

PEX Information

PEX Tubing The terms PEX pipe and PEX tube have been used interchangeably, however some manufacturers distinguish beween the two by manufacturing to different inside/outside diameters. For example, PEX pipe may be manufactured to IPS-ID (iron pipe size, inside diameter controlled) sizes with varying thickness to meet pressure requirements, while PEX tube may be manufactured to CTS-OD

Metallography and Microstructure of Aluminum and Alloys

Compared to many other metals and alloys and many other materials, such as carbides, ceramics and sintered carbides, aluminum and its alloys are low in strength and hardness. Aluminum is a soft, silvery metal with a face-centered cubic crystal structure, a hallmark of ductile metals. Its softness makes it somewhat difficult to prepare but the alloy is not sensitive to problems that plague

PCB Manufacturing Process

Circuit boards should be rigorously compatible with, a PCB layout created by the designer using PCB design software.Commonly-used PCB design software includes Altium Designer, OrCAD, Pads, KiCad, Eagle etc. NOTE: Before PCB fabrication, designers should inform their contract manufacturer about the PCB design software version used to design the circuit since it helps avoid issues caused by

ANODIZING of ALUMINUM Intro FAQs

Aluminum alloys may contain copper, silicon, zinc, magnesium, and other alloying ingredients, but only the aluminum portion can be converted to aluminum oxide. So alloys that are closer to pure aluminum will offer a clearer look when thin coatings are applied, and can generally accept a thicker anodized layer with less unsightly discoloration.
