About die casting alloys with Pace Industries

Zinc-aluminum (ZA) alloys have a slightly higher melting range of 800F to 900F (426C to 482C). Aluminum and magnesium alloys are considered to be moderate melting point alloys, being cast in the 1150F to 1300F (621C to 704C) range. Copper alloys are considered to be high melting point alloys, over 1650F (899C).

The Difference Between Aluminum, Magnesium and Zinc

The greater tendency of the zirconium-containing alloys to oxidize is overcome by the use of specially developed melting processes. The two magnesium-zinc-zirconium alloys originally developed, ZK51A and ZK61A, exhibit high mechanical properties, but suffer from hot-shortness cracking and are nonweldable.

The effects of holding time and concentration of SF6 on the protection of AZ91D magnesium alloy were investigated in a sealed furnace with a cover gas mixture of N2 and SF6. The morphology, thickness, composition and structure of the surface films were also studied. The results show that the surface film is compact with a thickness of 0.6 to 1.4 μm, containing F and Mg elements with an atomic

Welding of Magnesium Alloys

To date magnesium alloys have not usually been welded except for some repaired structures because of the occurrence of defects such as oxide films, cracks, and cavities (Haferkamp et al., 2000). However, the broader application of magnesium alloys requires reliable welding processes. Magnesium alloy components may be joined using mechanical

Melting Point of Metals Alloys

What is a melting point? The melting point of a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure; at the melting point, the solid and liquid phases exist in equilibrium. A substance's melting point depends on pressure and is usually specified at standard pressure in reference materials.
