Abstract: Disclosed herein are magnesium alloys and methods of making and use thereof. For example, disclosed herein are magnesium alloys comprising: from 0 to 1.5 wt. % Zn; from 0 to 1.5 wt. % Al; less than 0.2 wt. % Ca; from 0.2 to 0.4 wt. % Ce; from 0.1 to 0.8 wt. % Mn; and the balance comprising Mg. In some examples, the magnesium alloy comprises less than 1 wt. % Zn. In some examples, the magnesium alloy comprises less than 1 wt. % Al. In some examples, the magnesium alloy exhibits substantially no incipient melting when extruded with a ram speed of from 1.00 to 10.00 ipm. In some examples, the magnesium alloy is substantially free of a Mg2Ca phase, an AlCaMg phase, an Al2Ca phase, a Ca2Mg6Zn3 phase, or a combination thereof. In some examples, the magnesium alloy is substantially free of a Mg2Ca phase.

Abstract: The present invention provides a high thermal conductivity aluminum alloy, which comprises the following components in percentage by weight: Al: 80%-90%; Si: 6.5%-8.5%; Fe: 0.2%-0.5%; Zn: 0.8%-3%; V: 0.03%-0.05%; Sr: 0.01%-1%; graphene: 0.02%-0.08%. In the high thermal conductivity aluminum alloy of the present invention, alloying elements including Si, Fe, and Zn are optimized; Sr, V, graphene, among others are added. The amount of each component is controlled so that they coordinate to ALLOW high thermal conductivity, good casting performance and excellent semi-solid die-casting property. Graphene is introduced to the high thermal conductivity aluminum alloy of the present invention to exploit the good thermal conductivity of graphene, allowing the formation of a high thermal conductivity aluminium alloy.
