Products

Alloys
With over 50 years of valuable experience in the production of master alloys, AMG has become one of the leaders in this sophisticated business worldwide.

Through stringent testing (e.g. visual, black light, and X-ray inspections) AMG is able to provide world-class quality products that meet the highest technical requirements.

AMG offers a wide range of high-quality products for a number of specialized sectors including the following:

  • Aerospace industry
  • Leisure industry
  • Automotive industry
  • Power plants
  • Chemical plant construction
  • Ship-building
  • Off-shore technology and other applications

AMG’s master alloys, e.g., vanadium aluminum (VAl), molybdenum aluminum (MoAl), and ferroniobium (FeNb), are used in the titanium and super alloy industries as alloying elements to improve the mechanical properties of final Titanium or Ni-based super -alloys such as anti-corrosion and heat resistance. The hydrogen storage alloy Hydralloy C5, capable of chemically storing hydrogen, rounds off this product range.

The hydrogen storage alloy Hydralloy CTM, which is used as storage end alloy rounds off this product range.

Titanium Aluminides
Light, strong and high temperature resistant – these are the requirements on high performance engine materials for both aircraft and automotive applications. The major objective is to increase efficiency and decrease fuel consumption. Due to their low density of about 4 g/cm³ and high strength level up to 800 °C, intermetallic Titanium Aluminide (TiAl) materials are the most promising candidates to meet today´s and future challenges.

Since the early 90’s, AMG has developed and industrialized both TiAl based alloys and corresponding manufacturing technologies for ingot materials and semi-finished products. Based on outstanding materials expertise, vacuum-based metallurgical melting technologies of the Ti industry have been successfully adjusted to the specific needs of this novel materials class.

Materials science meets Technology. This formula sums up AMG’s market leadership. AMG sets worldwide standards in terms of the purity, dimensional and alloy variety, materials homogeneity and reproducibility of industrially manufactured TiAl semi-finished products for subsequent processing to components via casting, wrought processing or mechanical machining.

As a reliable supplier of TiAl to all advanced civil aircraft engine programs, AMG makes a vital contribution to the idea of green mobility: less fuel consumption, less noise, and increased overall efficiency. Ultra-light weight TiAl valves are back in racing engines (Formula 1, Moto GP) again – thanks to renewed technical regulations. This is the best opportunity for AMG to test TiAl materials under extreme thermo-mechanical stresses and will help us to further improve materials properties and manufacturing technologies for new TiAl-based products with outstanding performance.

AMG’s core competencies for TiAl include:

  • Development and production of adjusted master alloys for the manufacturing of TiAl-based alloys
  • Production of TiAl ingots via vacuum arc remelting (VAR) processing
  • Production of homogeneous TiAl semi-finished products via VAR skull melting and subsequent centrifugal casting into permanent molds
  • Recycling of qualified TiAl scrap materials into semi-finished products via vacuum induction skull melting (VIM) and subsequent centrifugal casting into permanent molds
  • Production of extruded TiAl rods and profiles
  • Production of rolled TiAl sheets based on homogenized cast parts
  • Extended materials diagnostics and chemical analyses

Coating Materials for thin film technology
PVD coating is now indispensable for modern surface optimization. In order to achieve high quality coatings, the quality of the starting materials is an important requirement.

AMG is one of the world´s leading manufacturers of sputter targets, arc cathodes and evaporation materials for the PVD thin film technology. AMG’s high-quality customized products made of pure metals, alloys, oxides and cermets are used for a wide range of applications. To produce special functional layers for architectural and automobile glass or in photovoltaics, you can use AMG’s products, e.g. ZnO/Al2O3 (AZOY®), chromium, titanium oxide or silicon.

AMG Coating Materials for wear resistance coatings, e.g. titanium aluminum, aluminum titanium, aluminum chromium or chromium significantly extend the life of tools and components and thus reduces production costs and environmental impact.

In optical applications, PVD layer systems such as hafnium oxide, zirconium oxide or tantalum oxide are used in the manufacture of e.g. laser mirrors, color filters, special filters and high-quality layer systems in ophthalmics.

During the production of AMG Coating Materials, environmental concerns are fully taken into account, a policy that is reflected in the outstanding environmentally friendly and energy-efficient production technologies and recycling programs for each product.

Recent Innovations

Reducing structural weight is one of the major ways to reduce carbon emissions and improve aircraft performance. Lighter and/or stronger materials allow greater range and speed and may also contribute to reducing operational costs. AMG has innovated a number of specialty alloys used to help reduce weight and improve the operational performance of aircraft.

Through extensive research beginning in the mid-1990s, AMG developed Titanium Aluminides (TiAl). Initial applications for this high strength, low weight material included valves for Formula 1 race cars and have evolved into alloys for aerospace applications. Titanium Aluminides offer superior high temperature performance with low weight for turbine blades and are as strong as nickel based alloys, but at only half the weight. These alloys will allow for smaller aerospace engines, reduced fuel consumption and less hazardous emissions, thus reducing the impact on the environment.
