Aluminum master alloys are based on aluminum with high relatively percentage, and combined with other elements. Master alloys are produced in various shapes, for example, ingot, piglet, waffle, coiled rod, conticast, and splatter. The reasons for adding master alloys to melt are composition adjustment and structure control. Such properties include mechanical strength, electrical conductivity, ductility, castability, and surface appearance.
According to the publication of The Aluminum Association Inc., add master alloys to melting with specific proportion is available for composition adjustment and structure control, reducing slag and hydrogen so as to achieve the standard of ASTM. Using master alloys instead of pure metals can be an economical, technical, and efficient way for cost down and time saving. |
