AMG Aluminum is a customer-focused, technology-driven organization dedicated to innovation, quality, technical expertise, and rapid response to customer needs.
For more than 80 years, AMG Aluminum has earned a trusted reputation for reliable delivery of consistently dependable aluminum grain refiners and master alloys anywhere in the world. Headquartered in Wayne, PA, AMG Aluminum, a business unit of AMG Advanced Metallurgical Group N.V., is the combination of AMG Aluminum North America, LLC, AMG Aluminum UK Limited, AMG Aluminum Brazil (aluminum activities of LSM Brazil S.A.), AMG Aluminum Mexico, S.A. de C.V., and AMG Aluminum China Limited.
With over 350 employees and five ISO 9001 manufacturing plants in the United States, Brazil, England, and China, AMG Aluminum is a world-leading provider of grain refiners and master alloys for the aluminum industry. AMG Aluminum offers a wide range of products including grain refiners, master alloys, compacted additives (ALTAB™), chemicals and fluxes and rod feeders.
What We Do
The success of the aluminum industry is dependent on alloys that, for example, reduce automobile weight, promote forming for various products such as aluminum beverage cans, and increase the performance of electric transmission cables. AMG Aluminum’s development of grain refiners and master alloys has helped to facilitate these innovations.
From the earth’s crust to a red slurry and then white powder to a shiny piece of commercially pure metal, aluminum’s journey finds its way into our daily lives, from the car we drive to the electricity that enters our homes and businesses. From beverage cans to sports and leisure equipment to aircraft and electronic equipment, the life-cycle restarts with the recycling back to the shiny metal.
AMG Aluminum’s products are used in several stages of the life cycle of aluminum. We provide grain refiners and master alloys used during melting and casting of aluminum and its alloys.
1. Bauxite Mining
The aluminium production process starts with the mining of bauxites, an aluminium rich mineral in in the form of aluminium hydroxide. About 90% of global bauxite supply is found in tropical areas.
Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites.
3. Primary Aluminum
At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950℃. Electric currents are then induced in the mixture at 400 kA or above; this current breaks the bond between the aluminium and oxygen atoms resulting in liquid aluminium settling at the bottom of the reduction cell.
4. Grain Refiners & Master Alloys
Grain refiners are produced using primary aluminium, titanium and boron salts. A master alloy is a pre-alloyed concentrate or mixture of alloying elements. They are used to add all the major alloying elements in one form to the base metal.
The casting process to produce rolling slab or extrusion billet is the vertical Direct Chill (DC) process.
The malleability of aluminium means it can be easily rolled into thin sheets. To that end, aluminium alloys are cast into rectangular beams up to 9 metres in length, these are then rolled into sheets from which aluminium foil and beverage cans are made, as well as parts of automobile bodies and a vast array of other products.
The process where the aluminium is shaped to its required form. This process is used for making the vast majority of aluminium products from spectacle frames, telephone bodies, aeroplane fuselages or spaceship bodies.
