Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.

A hermetic sealing approach involves welding an Aluminum cover onto a low-cost Aluminum housing. According to an example embodiment of the present invention, a metal housing having a base and sidewalls extending upward therefrom is adapted to receive and couple to an HDD arrangement. The metal housing is formed using material and processing (e.g., cold formed or die cast Aluminum) that are relatively inexpensive. A feedthrough arrangement including a plurality of communication pins extends through an opening in the base and is coupled thereto, with the communication pins adapted to pass signals between the inside and the outside of the metal housing. A metal cover is welded to an upper portion of the sidewalls and, with the feedthrough arrangement, hermetically seals the metal housing.

Aluminum-silicon alloy having reduced microporosity
An aluminum silicon die cast alloy having a very low iron content and relatively high strontium content that prevents soldering to dies into die casting process. The alloys of the present invention also have a modified eutectic silicon and modified iron morphology, when iron is present, resulting in low microporosity and high impact properties. The alloy comprises 6-22% by weight silicon, 0.05 to 0.20% by weight strontium and the balance aluminum. Preferably, the alloy of the present invention contains in weight percent: 6-20% silicon, 0.05-0.10% strontium, 0.40% maximum iron and most preferably 0.20% maximum iron, 4.5% maximum copper, 0.50% maximum manganese, 0.60% maximum magnesium, 3.0% maximum zinc, balance aluminum. On cooling from the solution temperature, the strontium serves to modify the eutectic silicon structure as well as create an iron phase morphology change if iron is present, facilitating feeding through the aluminum interdendritic matrix. This, in turn, creates a finished die cast product with extremely low levels of microporosity defects. The strontium content also appears to create a non-wetting monolayer of strontium atoms on the surface of a molten casting, preventing die soldering, even at very low iron contents. The alloy may be used to cast any type of object and is particularly suited for casting outboard marine propellers, driveshaft housings, gear case housings, Gimbel rings and engine blocks.
