The Magnesium & Manganese Content in Aluminum Alloy

Basic Aluminum Casting Co.

For over half a century The Basic Aluminum Casting Company has been a privately held, financially solid die casting company with a professional integrity matched by few in today’s industry.diecasting

At The Basic Aluminum Casting Company, we bring quality die casting with delivery and pricing achieved through a sound business organization. Centrally located in Cleveland, Ohio, we’re easily accessible across the Midwest and the entire United States. Occupying over 55,000 square feet at our plant, Basic has serves the transportation and general manufacturing industries and beyond! The Basic Aluminum Casting Company can be best described as an engineering company with one simple trait – creating die cast products  from listening and understanding our customer’s needs.  A strong commitment to that and a focus on quality has enabled us to continue to be one of the best and oldest names in the industry.


Alumunum die cast alloys are typically comprised of various constituents which effect the overall characteristics of the alloy

Magnesium- is usually controlled at a low level (.1%) in many of the popular die cast alloys in order to minimize brittleness and loss of ductility.

Manganese- is a desirable alloying element in increasing strength and ductility of aluminum alloys. In small additions, manganese combines with iron to change the iron-rich phases in the microstructure from needle-like, brittle precipitates to more ductile plates or “broken needles” in random orientation. Manganese must be carefully balanced with iron content (necessary to prevent soldering) to avoid sludge formation, the latter being a complex containing iron, manganese, and chromium.
