Embodiment Construction

[0032] A semi-softened high-copper low-manganese aluminum alloy material is characterized in that: the mass percentage of each component in the material is as follows:

[0033] Silicon Si: 0.03-0.08wt%;

[0034] Iron Fe: 0.10-0.20wt%;

[0035] Copper Cu: 0.4-0.6wt%;

[0036] Manganese Mn: 0.05-0.2wt%;

[0037] Yttrium Y: 0.005-0.1wt%;

[0038] The rest is aluminum; the mass percentages of all the above components add up to 100%.

[0039] A production process of a semi-softened high-copper low-manganese aluminum alloy material: Pre-preparing aluminum liquid according to the composition ratio of the aluminum alloy material to ensure that the main components of the aluminum liquid are silicon Si: 0.03-0.08wt%, iron Fe: 0.10- 0.20wt%, copper Cu: 0.4-0.6wt%, manganese Mn: 0.05-0.2wt%, yttrium Y: 0.005-0.1wt%, the rest is aluminum; after that, the high-efficiency powder spraying refining agent is passed into the holding furnace with aluminum liquid Refining is carried out in th...

Abstract

The invention provides a semi-softened high-copper low-manganese alloy material. No hole is produced in the extrusion process, an extrusion thin pipe is not likely to be broken, and extrusion fluidityis good. The material is prepared from, by mass, 0.03-0.08wt% of Si, 0.10-0.20wt% of Fe, 0.4-0.6wt% of Cu, 0.05-0.2wt% of Mn, 0.005-0.1wt% of Y and the balance Al. The sum of the mass percents of thecomponents is 100%.

Description

technical field [0001] The invention relates to the technical field of metallurgy, specifically a semi-softened high-copper and low-manganese aluminum alloy material, and the invention also provides a manufacturing process of the aluminum alloy material. Background technique [0002] When the existing aluminum alloy material is extruded to form a condensing thin tube, pores are likely to produce holes, impurities are likely to be damaged, and its extruding fluidity is poor, so that the aluminum alloy material is not suitable for extrusion forming a condensing thin tube. Contents of the invention [0003] In view of the above problems, the present invention provides a semi-softened high-copper and low-manganese aluminum alloy material, which does not produce leaks during the extrusion process; and the extruded thin tube is not easily broken and has good extrusion fluidity. [0004] A semi-softened high-copper low-manganese aluminum alloy material is characterized in that: t...
