KBM Affilips produces a complete range of alloys for the global aluminium industry, including the aluminium-manganese splatter master alloy. These master alloys are of superior quality and are used in aluminum wrought alloys and foundry alloys for composition adjustments and structure control.
By adding manganese to aluminium, strength and hardness increases and ductility reduces.The KBM Affilips AlMn60 splatter was originally developed for the aluminium industry for producing wrought alloys,the majority of which contained some manganese.
Typical levels are around 0.5% Mn for solid state grain growth control in the medium and high strength alloy range, and extend to 1.3% Mn for strengthening pure aluminium.
60% manganese-aluminium is a true alloy, which is created in the liquid state before rapid solidification by splat casting. The final product includes individual pieces of randomly shaped flake, with an average thickness between 2 and 5mm.
The splatter shatters on contact with hot molten metal due to high internal stress. This coupled with a considerable surface to volume ratio ensures a short dissolution time.
Unlike tablets or briquettes, AlMn60 splatter offers complete recovery of both the manganese and the aluminium contained. Reliability is also ensured by the absence of gravity segregation of undissolved manganese, which is a common cause of composition variations in different furnace charges.
The AlMn splatter master alloy is found in the following forms:
