Comparison of alloys 6060, 6063 and AD31
See. table 1 and figure below. Alloy 606035 – internal company HYDRO c alloy narrowed intervals of chemical elements in the alloy 6060. This alloy is often used in the production of aluminum profiles for walling – window, doors, facades.
- Thermally hardenable
- Partial analogues: alloys 6063 and AD31.
- Compared with 6063 AD31 and abortion 6060 It has an excessive content of Si relative to the magnesium. The silicon content is about the same, and the magnesium content is much lower: 0,35-0,6 instead 0,45-0,9 %.
- Maximum iron content: 0,30 compared with 0,35 % in 6063 and 0,5 % in AD31.
- The place of alloy 6060 among other 6xxx series alloys – look. picture below.
