Information profile @ a Glance
- A master alloy is a base metal such as aluminum, copper or nickel
combined with a relatively high percentage of one or two other elements
- Master alloys are produced in various shapes. Examples are: ingot,
waffle plate, rod in coils
- A master alloy is sometimes also referred to as "hardener", "grain
refiner" or "modifier" depending on its application.
- Aluminum master Alloys are often added to strengthen the alloy and
are therefore often referred to as "hardeners".
Another group is the "grain refiners", alloys that are added for
structure control.
- A grain refiner influences the aluminum alloy during the
solidification stage. Its role is to prevent cracking, combat shrinkage
porosity and increase the casting speed
- Aluminum-Boron or AlB or Boral is added to increase the electrical
conductivity of EC grade aluminium
- Aluminium Master Alloys and Compacted Alloying Products. Competition
in the markets for aluminium master alloys and compacted alloying
products is global, because of the relatively small number
of master alloy and alloying tablet manufacturers and the worldwide
operations of producers in the
aluminium industry. In most markets, the Company faces competition to
varying degrees from KBM Affilips B.V., KBAlloys, Inc. (and its UK
subsidiary, Anglo Blackwells, Ltd.), Aleastur (Asturiana de Aleaciones,
S.A.), Eramet S.A. and Hoesch-Metallurgie GmbH. Competition from
low-cost producers has
in the past pushed prices down and could do so again in the future.
