MPI Faculty and Members Present at the 2011 Die Casting Congress & Tabletop
By Author September 27, 2011
On September 19, the second session of the 2011 Die Casting Congress & Tabletop, Cast Materials I, featured the following presentations by MPI faculty and members:
Aluminum Alloy Development – Libo Wang, Diran Apelian, and Makhlouf Makhlouf – ACRC, Metal Processing Institute
The chemistry limits specified for die casting alloys are generally wide, which can cause large variations in the mechanical properties of die cast components. The objective of this work is twofold: (1) to tighten the chemistry specification of 380 alloy in order to minimize variation in its mechanical properties, and (2) to develop new premium grade aluminum-based die casting alloys that have enhanced mechanical properties. In this paper we report on the initial stages of the work, which involved the use of i-Select Al software to optimize the chemical composition of four aluminum-based die casting alloys.
Proposed “Environmentally Green” High Pressure Die Casting Alloys with Low Iron for Improved Mechanical Properties and Strontium for Die Soldering Resistance – Ray Donahue, Mercury Marine
This paper describes a new die cast alloy technology that relies on strontium instead of iron for die soldering resistance and provides specific compositions that can replace all current conventional die cast alloys. It is estimated the annual CO2 emission savings from the complete conversation of the die cast industry to these “low iron – high strontium” die cast alloys amount to approximately 23 million tons [i.e., 46,000,000,000 pounds] CO2 emissions annually. Similarly, the energy savings are estimated as 21,800,000,000 kWh – the environmental equivalent of providing enough energy to power 2 million households for a year.
Calculation of Aluminum Alloy Properties – Libo Wang, Diran Apelian, and Makhlouf Mahlouf – ACRC, Metal Processing Institute
The chemistry limits specified for die casting alloys are generally wide, which can cause large variations in the mechanical properties of die cast components. In many cases, there is a strong need to minimize these variations in properties in order to enable casting conversions to meet the demands of the application. In many other cases, the requirement of the application necessitates the use of a premium grade high performance alloy. Therefore, the objective of this work is twofold: (1) to tighten the chemistry specification of 380 alloy in order to minimize variation in its mechanical properties, and (2) to develop new premium grade aluminum-based die casting alloys that have enhanced mechanical properties.
