Six-series aluminum alloy template and production process thereof

Abstract

The invention belongs to the technical field of aluminum alloy production process, and relates to a six-series aluminum alloy template and a production process thereof. The six-series aluminum alloy template is prepared from the following elementary compositions in percentage by weight: 0.50-0.55 % of Si, 0.10-0.15 % of Fe, 0.05-0.10 % of Cu, 0.05-0.10 % of Mn, 0.55-0.60 % of Mg, less than or equal to 0.05 % of Cr, less than or equal to 0.05 % of Zn, less than or equal to 0.05 % of Ti, less than or equal to 0.25 % of La, less than or equal to 0.05 % of other single impurity content, less thanor equal to 0.15 % of total impurity, and the balance of Al. Through the improvement of alloy composition and production process, the final six-series aluminum alloy template has tensile strength of 280 Mpa, yield strength of 255 Mpa and elongation after fracture of 12.5 %, the mechanical properties are significantly improved, and the production needs of customers can be met.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy production technology, and relates to a 6-series aluminum alloy template and a production technology thereof. Background technique [0002] Aluminum is one of the most abundant elements in the earth's crust, with a content of 8.8%, ranking first among the four major metal elements and accounting for 1 / 3 of the entire mass of metal elements. Due to the improvement of aluminum technology, the aluminum industry is developing at an astonishing speed. By 2004, the world's aluminum output reached 29.8 million tons, of which my country's output was 6.8 million tons, ranking third in the world, and there were more than a thousand kinds of aluminum alloys. Due to the development of aluminum materials, the processing technology of aluminum has also been advanced by leaps and bounds. Due to its light weight, high specific strength, good low temperature performance, good plasticity, easy processing, ...
