The main die casting alloys are: zinc, aluminium, magnesium, copper, lead, and tin; although uncommon, ferrous die casting is also possible. [6] Specific die casting alloys include: zinc aluminium; aluminium to, e.g. The Aluminum Association (AA) standards: AA 380, AA 384, AA 386, AA 390; and AZ91D magnesium. [7]
Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in ...
6061 aluminium alloy (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. [ 2 ]
Aluminium–silicon alloys or Silumin is a general name for a group of lightweight, high-strength aluminium alloys based on an aluminum–silicon system (AlSi) that consist predominantly of aluminum - with silicon as the quantitatively most important alloying element.
The Giga Press program is a series of aluminium die casting machines manufactured for Tesla, initially by Idra Group in Italy. Idra presses were the largest high-pressure die casting machines in production as of 2020, with a clamping force of 55,000 to 61,000 kilonewtons (5,600 to 6,200 tf).
The Doehler Die Casting Co. of Toledo, Ohio were known for the production of Brastil, a high tensile corrosion resistant bronze alloy. [ 3 ] [ 4 ] Italy pioneered the use for coinage of an aluminium-bronze alloy called bronzital (literally "Italian bronze") in its 5- and 10-centesimi from 1939.
The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. [32] Aluminium is ductile , with a percent elongation of 50-70%, [ 33 ] and malleable allowing it to be easily drawn and extruded . [ 34 ]
Semi-solid metal casting (SSM) is a near net shape variant of die casting. [1] The process is used today with non-ferrous metals, such as aluminium , copper , [ 2 ] and magnesium . It can work with higher temperature alloys that lack suitable die materials.
