Alloys

  • 1070,2011,2012,2014,2017,2024,3003,5052,5083,6061,6063,7003,7075,6262A ~

Characteristics

2xxx alloys

Merit
  • High strength
  • Superior free cutting property
Demerit
  • Poor corrosion resistance (High Cu%)
  • Poor weldability (High Cu%)

6xxx alloys

Merit
  • Good extrudability, weldability and resistance to corrosion
  • Good for complex shape extrusion
Demerit
  • Relatively lower strength

Specification

  • Rod : Ф 4.5 ~ Ф 45
  • Pipe : Ф9 ~ Ф80
  • Straightness : Under 0.2mm / 1000 mm
  • Inner/Outter diameter tolerance : +0 ~ -0.04 mm
  • Thickness eccentricity : ± 0.1mm

Remark

  • Pb-free 2011 alloy (2012 & 2111 etc) replacing as-leaded alloy exporting to US and Europe is in production
  • 6262 can be used as alternative alloy to A2011 with high strength & good free-cutting characteristics. When higher levels of corrosion resistance are required, 6262 may be a suitable replacement.
