2. Aluminum industry in the United States - Wikipedia

   en.wikipedia.org/wiki/Aluminum_industry_in_the...

   Data from USGS. The aluminum industry in the United States in 2023 produced 860 thousand metric tons of aluminum from refined metal ore (primary production), at six smelters. In addition, US industry recycled 3.4 million tons of aluminum (so-called secondary production aluminum). [ 1] Total annual imports of metal and alloy for use in secondary ...

3. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation. This process starts by feeding plastic ...

4. Continuous casting - Wikipedia

   en.wikipedia.org/wiki/Continuous_casting

   Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has ...

6. Extrusion - Wikipedia

   en.wikipedia.org/wiki/Extrusion

   Extrusion. Extruded aluminium with several hollow cavities; T slots allow bars to be joined with special connectors. Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create ...

7. 6063 aluminium alloy - Wikipedia

   en.wikipedia.org/wiki/6063_aluminium_alloy

   6063 is the most common alloy used for aluminium extrusion. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames. [ 3] Applications requiring higher strength typically use 6061 or 6082 instead.
