Abstract

The invention discloses high-thermal-conductivity Ge-containing magnesium alloy suitable for cold chamber die casting and a processing technology thereof. The alloy is prepared from the following components in percentage by weight: 0.5-1.2wt.% of Ca, 2.4-3.5wt.% of Ge, 1.0-2.5wt.% of Mn, 2.4-3.8wt.% of Ni, 0.5-1.2wt.% of Y, 0.2-0.6wt.% of Nb and the balance of magnesium. The magnesium-calcium alloy has excellent die casting properties and excellent thermal conductivity and is expected to have a promotion effect of enabling fine new materials independently researched and developed in China to occupy the market of international fine new materials.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a magnesium-calcium alloy. Background technique [0002] Magnesium alloy is an alloy composed of magnesium and other elements. It is the lightest metal structure material used in aircraft, spacecraft and rocket missile manufacturing industries. Magnesium is lighter in weight and lower in strength than aluminum, and is mainly used in the manufacture of low-load parts. Magnesium alloy has high anti-vibration ability, can absorb large energy when subjected to impact load, and has good heat absorption performance, so it is an ideal material for manufacturing aircraft hubs. Magnesium alloy is very stable in gasoline, kerosene and lubricating oil, suitable for manufacturing engine gear casings, oil pumps and oil pipes, and is used to manufacture rocker arms, flaps, Moving parts such as doors and rudder surfaces. Magnesium alloy products are widely used in civil aircraft and military ...
