Abstract

The invention discloses magnesium alloy which mainly comprises the following elements in percent by weight: 7.2% to 8.5% of aluminum, 0.007% to 0.01% of nickel, 0.30% to 0.70% of manganese, 0.20% to 0.30% of zinc and the balance of magnesium. The manufacturing technology comprises the following: step 1, all elements are added into a smelting furnace according to weight percentages, heated to 665 plus or minus 5 DEG C and stirred for 3 to 5 minutes; step 2, the time interval is 4 hours; a refining agent of 2 kg is taken per time and placed in a slag removing machine; the nitrogen gas of about 4.5 kg is introduced for pressurization and injected into melting liquid through a steel tube and the melting liquid is boiling for 3 to 5 minutes; the steel tube is taken out and rested for 5 to 10 minutes; and then the surface residual slag is removed; step 3, mould pouring is conducted; step 4, cooling and demoulding are performed; and step 5, forming is achieved.

Description

technical field [0001] The invention belongs to the technical field of magnesium alloys, and in particular relates to a magnesium alloy specially used in the field of automobile magnesium alloy wheel manufacturing, a manufacturing process and a wheel hub made thereof. Background technique [0002] As the lightest engineering metal material, magnesium alloy has a series of unique features such as light specific gravity, high specific strength and specific stiffness, good damping and machinability, good thermal conductivity, strong electromagnetic shielding ability, good vibration damping and easy recycling. It has become the material of choice for modern automobiles and 3C industries, and is known as "the green engineering material of the 21st century". [0003] With the increasing demands of domestic and international markets after my country's accession to WTO and the implementation of the country's western development strategy, the magnesium industry is facing great opport...
