The manufacturing method for 6061 T6 aluminum square tubing


This is a common manufacturing method, involving the heated 6061 aluminum alloy billet being extruded into a die with a square cross-sectional shape using high pressure. The raw material is shaped into the form of a square tube and then cut and trimmed to the desired dimensions after cooling.


This method uses 6061 aluminum sheets or coils, which are joined together using various welding techniques to form square tubing. Common welding methods include TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and electron beam welding. After welding, the tubing requires trimming and quality inspection.


The casting method is suitable for manufacturing square tubing with larger sizes and special requirements. In this method, aluminum alloy is melted and then poured into a square mold. After cooling, it takes on the structure of square tubing.


This method involves stretching a 6061 aluminum alloy billet through a square die to gradually form the cross-section of the square tubing. It is typically used for manufacturing smaller-sized square tubing, achieving the desired dimensions and shape through multiple extrusion passes.
