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 Brasil (aluminum activities of LSM Brasil 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.
2. Alumina Production
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 smelter
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. Aluminium ingot
Primary aluminium is cast into ingots and shipped to customers or used in the production of aluminium.
5. Grain Refining and Master Alloys
9. End products
9.1 Aluminium billets
9.4 Engine block
Use of Aluminium
Aluminium has been used commercially for over 120 years and has established its use in many industries due to its diverse range of physical, chemical and mechanical properties such as:
- Low density- Aluminium is only one-third the weight of steel
- Aluminium is highly resistant to most forms of corrosion
- It is a superb conductor of electricity
- Aluminium is non-magnetic and non-combustible
- Aluminium is non-toxic and impervious
- Aluminium is strong and ductile, and it is easy recycled
- It is also has high reflectivity, heat barrier and heat conduction properties
Aluminium and its alloys make it an ideal material of choice for a wide range of applications in transport, building and construction, packaging and general engineering. Aluminium alloys are available in the wrought from, as rolled products, extrusions and forgings, as well as being cast by all of the congenital technologies such as pressure die casting, permanent mould and chill casting, sand casting and investment casting.
