Alumina is properly called aluminum oxide, which is a chemical compound comprised of aluminum and oxygen molecules (Al2O3). After aluminum oxide refining from bauxite, alumina generally looks like a white powder similar to table salt or granular sugar. Aluminum oxide is typically referred to as alumina, but may also be called aloxide, aloxite or alundum, […]

A finer grain size promotes improved casting soundness by minimizing shrinkage, hot cracking, and hydrogen porosity. Under normal solidification conditions spanning the full range of commercial casting processes, aluminum alloys without grain refinement exhibit coarse columnar and/or coarse equiaxed structures. A fine grain structure also minimizes the effects on castability and properties associated with the […]

The basic process of aluminum alloy plate continuous casting and rolling process is: aluminum ingot → melting furnace → static furnace → degassing unit→ filtration unit→ casting nozzle → rolling mill → intermediate unit → coiling machine. It is characterized by casting and rolling molten aluminum into 6-10mm thick, 650-1400mm wide slab and rewinding. And […]

Honeycomb filter material has natural chemical adsorption (affinity) ability to oxides, and absorbs impurities (including particles smaller than the pore size) in the molten metal on the inner wall of the hole, which improves the filtering effect. The advanced extrusion production process makes the ceramic filter with a unique square and triangular design, which increases […]

Iron is the main impurity element in aluminum alloys. In the 6063 aluminum bar, the national standard stipulates that it is not more than 0.35. If a first-grade industrial aluminum ingot is used in production, the general iron content can be controlled below 0.25. However, if in order to reduce production costs, a large amount […]

Aluminum alloy smelting is one of the most important process links for the production of high-quality casting rods. Flux refining process for aluminum is an important process in aluminum alloy smelting. The main components of fluxes currently on the market are chlorides and fluorides. If the process is not properly controlled, slag, pores, coarse grains, […]

The aluminum liquid that 6061 aluminum rod sucks out from the electrolytic cell contains various impurities, so it needs to be purified before casting. In industry, casting purification methods such as clarification, flux, and gas are mainly used, and directional solidification and filtration methods are also used for purification. Flux Purification Non-sodium granulated flux purification […]

Aluminum rod and bar is produced by several different processes namely extrusion, rolling and coiling, or drawn directly from molten aluminum. These processes elongate the aluminum into circular or bar-shaped pieces that can be machined into all kinds of applications. Many machine and equipment parts, such as rivets, nails, screws and bolts, are made from […]

With the development of science and technology and industrial production, especially the rapid development of aerospace, missile, aviation and electronic technology, the quality requirements of aluminum alloys are increasingly strict, most deformed aluminum alloy materials. Molten Metal Purification Technology becomes an extremely important production process for aluminum alloys. Advanced purification technology is very important to […]

The aluminum can is often the subject of recycling success stories and statistics, but the recycling rates in the auto and building/construction industries are even higher. More than 90 percent of aluminum used in automotive and construction applications is recycled. Secondary Production is the process of recycling aluminum scrap into aluminum that can be used […]
